NONLINEAR HUNTING STABILITY OF HIGH-SPEED RAILWAY VEHICLE ON A CURVED TRACK UNDER STEADY AERODYNAMIC LOAD

Han Wu et al

Vehicle System Dynamics Vol 58, No. 2, 2020, p175-197 https://doi.org/10.1080/00423114.2019.1572202

ABSTRACT: This paper investigates the nonlinear hunting stability of a high-speed vehicle on a curved track under steady aerodynamic load. We fi rst established a nonlinear dynamic model of high-speed vehicle on a curved track while considering the eff ect of aerodynamic load. Then, we wrote a numerical simulation programme and verifi ed the validity. The following two types of aerodynamic conditions were concerned in this study: considering only the aerodynamic lift and considering the crosswind loads. The infl uence of aerodynamic load on the creep force, the restoring force and moment generated by gravity, and the equilibrium position of the vehicle on the curved track can all change the hunting stability.

Han Wu et al


ABSTRACT: This paper investigates the nonlinear hunting stability of a high-speed vehicle on a curved track under steady aerodynamic load. We fi rst established a nonlinear dynamic model of high-speed vehicle on a curved track while considering the eff ect of aerodynamic load. Then, we wrote a numerical simulation programme and verifi ed the validity. The following two types of aerodynamic conditions were concerned in this study: considering only the aerodynamic lift and considering the crosswind loads. The infl uence of aerodynamic load on the creep force, the restoring force and moment generated by gravity, and the equilibrium position of the vehicle on the curved track can all change the hunting stability. We calculated bifurcation diagrams, limit cycle motions, nonlinear critical speeds, and frequency spectrum considering those two types of aerodynamic conditions, then compared with those without considering the aerodynamic eff ects. The results show that multiple frequencies including double frequency, triple frequency, quadruple frequency, and high frequencies will appear in addition to the fundamental frequency when hunting motion occurs. The higher frequencies which are even times of fundamental frequency are caused by the deviation of equilibrium position from track centre, while the deviation of equilibrium position is generated by curve track or crosswind load. Additionally, a positive aerodynamic lift and a crosswind load in the centrifugal direction will decrease the vehicle’s motion stability, while a negative aerodynamic lift and a crosswind load in the centripetal direction can improve the stability.

Thomas Wolf

Part D: Journal of Automobile EngineeringVol 234, Issue 2-3, 2020, p390-408https://doi.org/10.1177/0954407019843004

ABSTRACT: With signifi cantly enhanced performance, the third generation of the Porsche Cayenne is even more closely oriented towards the principles of sports cars. In addition to improving the driving-dynamic characteristics, the aim of the development was to lower the drag as a contribution towards the reduction of fuel consumption and emissions. Increasing performance and a simultaneous reduction of drag are confl icting objectives, which led to a number of aerodynamic challenges during the development of the new Cayenne. In addition to detailed aerodynamic optimisations, the solution for the new Cayenne consisted of an extended adaptive aerodynamic concept, which enables a compromise between fuel consumption, performance, and comfort depending on the driving condition. The fi rst part of the concept comprises an extended air fl ap system that, for the fi rst time, enables complete closing of all cooling air inlets in the front end. The second part of the concept is reserved for the top-of-the-range V8 Turbo model and consists of a multifunctional deployable roof spoiler that adapts to the aerodynamic characteristics of the relevant driving condition and features an air-brake function as a highlight.

SLIDING-MODE CONTROL OF AUTOMOTIVE SELECTIVE CATALYTIC REDUCTION SYSTEMS WITH STATE ESTIMATION

Yao Ma et al

Part D: Journal of Automobile Engineering Vol 234, Issue 2-3, 2020, p630-644 https://doi.org/10.1177/0954407019853968

ABSTRACT: A sliding-mode controller for an automotive selective catalytic reduction system is designed to drive its ammonia surface coverage ratio to the target level. The proposed controller only requires NOx, temperature and air fl ow sensor measurement installed on most mass production

vehicles. Selective catalytic reduction systems have been widely equipped on diesel-powered ground vehicles to remove excessive NOx emissions. The tradeoff between NOx removal effi ciency and ammonia slip poses a control challenge on regulating the ammonia surface coverage ratio to a proper level in the presence of disturbance. In this study, a sliding-mode controller is designed with explicit consideration of measurement noise and actuator saturation. The fi nite time convergence of tracking error is proved by a Lyapunov approach. For implementation purpose, an observer of ammonia surface coverage ratio and ammonia slip is also designed to provide states feedback and fault diagnostic information. The closed-loop controller performance is evaluated under an urban driving scenario based on an experimentally validated model. Results demonstrate the robust tracking performance and estimation accuracy against bounded uncertainties. The overall NOx effi ciency is maintained with an acceptable ammonia slip level during the transient test cycle FTP75. (AUTH)

FROM FUNDAMENTAL STUDY TO PRACTICAL APPLICATION OF KEROSENE IN COMPRESSION IGNITION ENGINES: AN EXPERIMENTAL AND MODELING REVIEW

Kun Lin Tay et al


ABSTRACT: The use of kerosene in direct injection compression ignition engines is fundamentally due to the introduction of the Single Fuel Concept. As conventional direct injection compression ignition diesel engines are made specifi cally to use diesel fuel, the usage of kerosene will aff ect engine emissions and performance due to diff erences between the fuel properties of kerosene and diesel. As a result, in order for kerosene to be properly and effi ciently used in diesel engines, it is needful for the scientifi c community to know the properties of kerosene, its autoignition and combustion characteristics, as well as its emissions formation behavior under diesel engine operating conditions. Moreover, it is desirable to know the progress made in the development of suitable kerosene surrogates for engine applications as it is a crucial step

toward the development of reliable chemical reaction mechanisms for numerical simulations. Therefore, in this work, a comprehensive review is carried out systematically to better understand the characteristics and behavior of kerosene under direct injection compression ignition engine relevant conditions. In this review work, the fuel properties of kerosene are summarized and discussed. In addition, fundamental autoignition studies of kerosene in shock tube, rapid compression machine, fuel ignition tester, ignition quality tester, constant volume combustion chamber, and engine are compiled and evaluated. Furthermore, experimental studies of kerosene spray and combustion in constant volume combustion chambers are examined. Also, the experimental investigations of kerosene combustion and emissions in direct injection compression ignition engines are discussed. Moreover, the development of kerosene surrogates, their chemical reaction mechanisms, and the modeling of kerosene combustion in direct injection compression ignition engines are summarized and talked about. Finally, recommendations are also given to help researchers focus on the areas which are still severely lacking. (AUTH)

International Journal of Electric and Hybrid Vehicles Vol.12, No.2, 2020, p168-183 DOI: 10.1504/IJEHV.2020.106354

ABSTRACT: Phase change materials (PCM) are of attractive interest in electricity storage and power management applications. In this paper, PCMs are used for thermal management of an electric battery pack. Paraffi n with a melting temperature of 58°C, OM35 with melting temperature of 35°C, two PCMs (paraffi n and OM 35) were used for the study, as mixtures at two diff erent ratios (50 : 50 and 60 : 40). Computations and experiments were allotted to estimate the heat transfer, solidifying and melting characteristics of the PCM utilised in the Li-ion cell battery module. Since PCM has low thermal conduction, thermal

improvement techniques were investigated by inserting the copper plate into the PCM mixtures to boost the thermal conduction. PCM combination 50 : 50 is capable of holding battery running temperature compared to PCM combination 60 : 40. PCM combination 50 : 50 evidences to be ideal and lowered the operating temperature of the battery pack to 47°C. (AUTH)

BRAKE BLENDING AND TORQUE VECTORING OF ROAD ELECTRIC VEHICLES: A FLEXIBLE APPROACH BASED ON SMART TORQUE ALLOCATION

Luca Pugi et al


ABSTRACT: Application of regenerative braking on electric vehicles has a large impact on several aspects of design, implemented functionalities and overall performances of road vehicles. In particular, multi-quadrant capabilities and improved control performances of modern electric drives can be fully exploited to improve vehicle effi ciency, stability and overall environmental impact. Conventional, mechanical friction brakes are currently devoted not only to stop the vehicle but also to the actuation of safety related mechatronics systems such as electronic braking distribution (EBD), AntiBlockierSystem (ABS) and electronic stability control/program (ESC/ESP). The result is an over-actuated system of electrical (electric motors) and mechanical actuators (friction brakes), whose mixed, blended application has to be carefully optimised. In this work a simplifi ed approach is proposed in which concepts transferred from previous studies on high speed trains and autonomous vehicles are re-purposed and adapted in an innovative way to electric road vehicles.

MECHANISM ANALYSIS OF VEHICLE START-UP JUDDER BASED ON GRADIENT CHARACTERISTIC OF STRIBECK EFFECT

Renfei Yuan et al


ABSTRACT: This paper presents a profound mechanism investigation for vehicle start-up judder phenomenon using a combination of experiment and simulation. First, from the experimental analysis, the characteristic frequency of start-up judder is mainly concentrated at about 9 Hz. A 13-degree-of-freedom powertrain branched model is established to numerically reproduce experimental phenomenon. The validity and accuracy of simulation model in refl ecting the characteristics of start-up judder are verifi ed by the experimental results in time–frequency domain. Second, through analyzing clutch friction torque, it can be concluded that the closed-loop positive feedback mechanism caused by the negative gradient characteristic of Stribeck eff ect is the determining factor for the start-up judder. It promotes aggravated fl uctuation in rotational speed of clutch driven plate. The introduction process of negative damping that makes powertrain system divergent is explained in detail. Finally, two theoretical measures are proposed to suppress the vehicle start-up judder. One of the measures is to diminish the absolute value of the negative gradient. It weakens the aggravation eff ect of the closed-loop positive feedback and hence attenuates the start-up judder. Another measure is to change to positive gradient. It forms a closed-loop negative feedback process that causes the almost disappearance of start-up judder. The eff ectiveness of the two suppression measures verifi es the correctness of the start-up judder mechanism proposed in this paper. (AUTH)

OPTIMAL CONTROL OF REGENERATIVE HYDRAULIC COMPOSITE BRAKING SYSTEM BASED ON A VOLTAGE VARIABLE CHARGING CONTROL SCHEME

Jun-Cheng Wang et al


ABSTRACT: A double-loop optimal control strategy combined with a voltage variable charging control scheme is developed to enhance the effi ciency of energy recovery and improve control precision for a regenerative hydraulic composite braking system. The proposed voltage variable charging control scheme structure aims to regulate a regenerative braking torque using a charging voltage variation based on an existing battery management system. In addition, an experimental test was conducted to verify the eff ectiveness of the charging voltage control, and a fi rst loop optimal control was developed to evaluate the ideal ground braking force accurately by transforming several state variables into diff erential equations. A second optimal control loop was subsequently developed to track an ideal slip ratio using a full-information optimal sliding mode control method under the all-braking conditions. Simulation results corroborate that a composite braking system controlled by the proposed control strategy can implement the regenerative braking behavior precisely with a considerable high-energy recovery effi ciency.

ANALYTICAL MODEL AND MATERIAL EQUIVALENT METHODS FOR STEADY STATE HEAT PARTITION COEFFICIENT BETWEEN TWO CONTACT DISCS IN MULTI-DISC CLUTCH

Cenbo Xiong et al


ABSTRACT: The heat partition coeffi cient between two fi nite thickness contact discs during long-time sliding is studied with a coupled fi nite element method. Results show that the heat partition coeffi cient varies from its initial value to another steady state value rapidly instead of being a constant all the time. An analytical solution of the temperature fi eld under invariant heat fl ux input is deduced, which tells that there exists a unique critical thickness ratio between the contact discs that keeps the heat partition coeffi cient a constant. An equivalent method for single-material contact bodies is proposed that is capable of calculating the steady state heat partition coeffi cient for any thickness ratio. It reveals that the steady state heat partition coeffi cient only has relationship with the mass density and the heat capacity of

The temperature increase ahead of the second spray plays a more important role in promoting the overall ignition process regardless of the initial oxygen concentration. Moreover, the eff ect of species addition on the fi rst- and second-stage ignition processes is also analysed in detail. Diff erent from the results with other species addition, the presence of H2O2 and CH2O in the initial gas leads to the monotonical decrease with the increase in the initial gas temperature, T0.

ADAPTIVE FUZZY RADIAL BASIS FUNCTION NEURAL NETWORK INTEGRAL SLIDING MODE TRACKING CONTROL FOR HEAVY VEHICLE ELECTRO-HYDRAULIC POWER STEERING SYSTEMS

Heng Du et al


ABSTRACT: Due to parametric uncertainties, unknown nonlinearities, and dynamic external disturbances, it is a challenging and valuable task for heavy vehicle electro-hydraulic power steering systems to realize high-precision tracking control. To cope with this complex nonlinear tracking control problem, the integral sliding mode control is an extremely potential control method, which has strong robustness to model uncertainties and unknown disturbances, and can eff ectively reduce the steady-state error in tracking control process. However, the inherent chattering phenomenon of integral sliding mode control seriously aff ects its control performance. In order to suppress the chattering while ensuring robustness, adaptive fuzzy technique is adopted as an eff ective auxiliary means, which can not only deal with the inherent chattering problem of integral sliding mode control and a priori knowledge of the disturbance upper bound in controller design but also dynamically adjust the parameters in the fuzzy rules. Moreover, the designed adaptive fuzzy–integral sliding mode control scheme still needs the precise mathematical models of the control systems. But it is diffi cult to obtain the model for heavy vehicle electro-hydraulic power steering systems with highly complex and coupling properties. Therefore, to further improve the method, this paper presents a novel adaptive fuzzy–radial basis function

the materials and the thickness ratio. Based on this method, a two-step material equivalent method is further proposed for the contact discs that have friction linings on them. The solution shows that the steady state heat partition coeffi cient in this situation is also only determined by the material properties and the layer thicknesses. A test bench of multi-disc clutch is set up and a series of sliding experiments are conducted to validate the proposed equivalent methods and solutions of steady state heat partition coeffi cient. The measured experimental temperature variations show that the temperature level of the separator disc in the clutch is overestimated with the constant heat partition coeffi cient of semi-infi nite model, while it is close to those calculated results with steady state heat partition coeffi cient. Therefore, the temperature fi elds of the contact discs during long-time sliding with constant speed can be fi gured out effi ciently using the steady state heat partition coeffi cient with only small error, and these equivalent methods benefi t the multi-disc clutch design and temperature estimation in practical applications.

THE INFLUENCE OF INTERMEDIATE SPECIES ON THE COMBUSTION PROCESS OF N-DODECANE FLAME

Wanhui Zhao et al


ABSTRACT: Split-injection strategy is of great potential to reduce the pollutant emissions without deterioration of engine performance. The combustion of the previously injected fuel has great infl uence on the ignition of the subsequent second injection. In this study, the main infl uence of species formed in the fi rst injection on the ignition of the second injection is analysed in detail. Diff erent species are added into the fuel/air mixture to study the infl uence of the species formed in the fi rst injection on the combustion process of the second injection. Results show that the infl uence of species addition on the ignition delay is dependent on the initial temperature and oxygen concentration. The presence of acetylene (C2H2) and methane (CH4) prolongs the ignition delay regardless of initial temperatures or oxygen concentrations. However, ethylene (C2H4), hydrogen peroxide (H2O2), hydrogen (H2) and formaldehyde (CH2O)

TWO-LAYER MASS-ADAPTIVE HILL START ASSIST CONTROL METHOD FOR COMMERCIAL VEHICLES

Pai Peng et al


ABSTRACT: This study aims to develop a two-layer mass-adaptive control framework to improve the hill start assist performance of commercial vehicles equipped with an electronic parking brake system. In the fi rst layer, the desired pressure of the hill start assist control is proposed, then a logic threshold control method is employed to track the time-varying desired pressure. Due to the frequently changing load of the commercial vehicles, the second layer is utilized to estimate the vehicle mass online. The proposed mass-adaptive control method is evaluated via a co-simulation platform involving MATLAB/Simulink, TruckSim and AMESim, and is compared with a one-layer scheme without mass estimation. Finally, we further demonstrate the feasibility and robustness of the two-layer mass-adaptive hill start assist framework in vehicle experiments. (AUTH)

TWO-LAYER STRUCTURE ALGORITHM FOR ESTIMATION OF COMMERCIAL VEHICLE MASS

Liuliu Cai et al


ABSTRACT: Aiming at the problem of mass estimation for

commercial vehicle, a two-layer structure mass estimation algorithm was proposed. The fi rst layer was the grade estimation algorithm based on recursive least squares method and the second layer was a mass estimation algorithm using the extended Kalman fi lter. The estimated grade was introduced as the observation quantity of the second layer. The infl uence of the suspension deformation on grade estimation was considered in the fi rst layer algorithm, which was corrected in real time according to the mass and road grade estimated by the second layer algorithm. The proposed estimation algorithm was validated via a co-simulation platform involving TruckSim and MATLAB/Simulink. Finally, a road test was carried out, and the evaluation method using the root mean square error was proposed.

SMARTPHONE LOCALIZATION INSIDE A MOVING CAR FOR PREVENTION OF DISTRACTED DRIVING

Gregory Johnson and Rajesh Rajamani


ABSTRACT: This paper discusses a novel algorithm to automatically identify the position of a smartphone inside a moving vehicle, so as to detect whether it is being used by the driver or just a passenger of the car. This detection has applications to the prevention of distracted driving and can be used to automatically disable phone features such as texting when the phone is located in the driver’s seat. The challenges in the smartphone localisation problem come from the need to entirely use only accelerometers and gyroscopes already available on a typical phone, and the need to allow for any unknown 3-dimensional orientation of the phone while being carried by the driver or passenger of the car. First, the phone’s real-time orientation is determined by identifying the vehicle’s longitudinal and vertical axes in the phone reference frame. This provides the rotational matrix for conversion of accelerations and angular velocities measured on the phone to accelerations and angular velocities about the car axes. Next, the front-

to-back pitching dynamics of the car during deceleration and the side-to-side roll dynamics during turning are characterised to detect whether the phone is in the driver’s seat. The characterisation of the roll and pitch dynamics are formalised using cross-covariances of sensor signals and a machine learning algorithm. Both simulations and extensive experiments are used to show that the developed system can accurately determine if the phone is being carried by the driver. The developed technology can be extremely useful for iPhones and other smartphones which can currently only detect whether the phone is on a moving car, but cannot detect whether it is being used by a driver or a passenger.

PRESSURE CONTROL OF ELECTRO-HYDRAULIC SERVO LOADING SYSTEM IN HEAVY VEHICLE STEERING TESTBOARD BASED ON INTEGRAL SLIDING MODE CONTROL

Heng Du et al


ABSTRACT: Heavy vehicle steering testboard has a key role to play in the fundamental research of heavy vehicle steering performance, and pressure control of electro-hydraulic servo loading system is the precondition and foundation for achieving accurate dynamic loading of heavy vehicle steering testboard. Commonly used proportional–integral–diff erential control easily fails to track target pressure signal with high amplitude and frequency, while integral sliding mode control is capable of realizing pressure tracking with high accuracy in engineering for its strong robustness and simplicity. A nonlinear mathematical model of electro-hydraulic servo loading system is established, including the nonlinear characteristics of valve-controlled cylinder system and tire elastic force, and an integral sliding mode controller is also designed in this paper. For further comparison and analyses, based on particle swarm optimization and integral of the time absolute error criterion, a proportional–integral–diff erential self-tuning controller of electro-hydraulic servo loading system is proposed as well, and the corresponding optimal proportional–integral–diff erential control gains

are obtained. Both numerical simulation and experiment results confi rm that, compared with proportional–integral–diff erential self-tuning control, integral sliding mode control can eff ectively suppress the disturbance of external loads and reach a better pressure tracking performance. (AUTH)

VEHICLE LANE KEEPING SYSTEM BASED ON TSK FUZZY EXTENSION CONTROL

Hongbo Wang et al


ABSTRACT: In the traditional lane keeping system, a single control algorithm is used for global-region control, which often results in poor control eff ect in some control areas. In view of this problem, a control method combining the extension control and Takagi-Sugeno-Kang fuzzy control is proposed for lane keeping system control. The extension control strategy based on the idea of control with area division divides diff erent control regions according to the states of the system, and adopts diff erent control algorithms in diff erent control areas to address the limitation of a single control algorithm. For the randomness and inaccuracy of artifi cial experience in control domain division, a method for control domain division based on the density distribution of characteristic plane is proposed in this article. In order to further improve and explore the performance of extension control, Takagi-Sugeno-Kang extension controller is designed with Takagi-Sugeno-Kang fuzzy control theory, and the extension control performance is improved when switching among diff erent control algorithms. The proposed control strategy is simulated and tested on the CarSim/Simulink joint simulation platform and the CarSim/LabVIEW hardware-in-loop test bench, respectively. The results show that the proposed control strategy can eff ectively keep the vehicle near the center line of the lane, and both the lane keeping control accuracy and vehicle stability are improved, which guarantees driving safety and comfort.

TRAJECTORY PLANNING AND COMBINED CONTROL DESIGN FOR CRITICAL HIGH-SPEED LANE CHANGE MANOEUVRES

Hadi Sazgar et al


ABSTRACT: The purpose of this research is to develop an advanced driver assistance system for the integrated longitudinal and lateral guidance of vehicles in critical high-speed lane change manoeuvres. The system consists of two parts: trajectory planning and combined control. At the fi rst, by considering the TV position and the available range of longitudinal acceleration, several trajectories with diff erent accelerations are generated. Then, by taking into account the vehicle and tyre dynamics, the most appropriate trajectory is selected. Therefore, the chosen trajectory is collision free and dynamically feasible. Because the trajectory planning is carried out algebraically, it has low computational cost. This is especially valuable in the experimental implementations. At the second part of the study, using a robust combined longitudinal-lateral controller, the control inputs are determined and transmitted to the brake/throttle and steering actuators. Both in the trajectory planning and combined control design, the nonlinear tyre dynamics and the dynamics of throttle and brake actuators are considered. To evaluate the performance of the proposed guidance algorithm, a full CarSim dynamic model is utilized. The simulation results for critical high-speed lane change manoeuvres confi rm that the proposed trajectory planning method works eff ectively. The tracking error is also very small and the yaw stability is guaranteed. (AUTH)

A DRIVING CYCLE CONSTRUCTION METHODOLOGY COMBINING K-MEANS CLUSTERING AND MARKOV MODEL FOR URBAN MIXED ROADS

Yuhui Peng et al


ABSTRACT: With the rapid urban expansion in China, there is considerable development of road networks, mainly comprising arterial roads, expressways, and loop-lines in urban regions. In addition to typical short trips, certain number of long trips are also included in the driving behavior for urban areas. In view of the new characteristics of urban mixed roads, a driving cycle construction methodology combining k-means clustering and Markov model method is proposed based on about 2.4 million seconds of driving data collected from seven passenger cars without route planning. In order to cluster micro trips into appropriate categories corresponding to diff erent types of roads, the Silhouette equation is introduced to determine the appropriate clustering strategy and the error of artifi cial factors is restrained. The constructed driving cycle, comprising a 1200 s speed-time series, is developed based on the assessment of speed–acceleration frequency distribution and estimation of six characteristic parameters. According to the results, the average diff erence rate of six characteristic parameters is only 4.31%, which demonstrates the eff ectiveness of the proposed method. (AUTH)

Ramesh Pandiyarajan and Lenin Natesan Chokkalingam


ABSTRACT: The key challenges faced by many of the industries in the present scenario is to develop a high power density electrical machine. The advancements in material technology help the industries to enhance the power density as well as the effi ciency of an electrical machine to a greater

extent. Conductors play a major role in improving the machine’s performance. In this paper, the role of conducting materials in high power density electrical machines are discussed. Graphene is an advanced nanomaterial that exhibits excellent conductivities with low mass density. Using graphene coated windings, the weight and volume of the machine can be reduced signifi cantly. In order to understand the prominent features of the nanomaterial based conductors, a case study has been carried out in diff erent electric vehicles such as Toyota Prius (2017), Nissan LEAF and BMW i3. Moreover, a major constraint in high power density machine is the temperature rise, which is discussed at the end. (AUTH)

Chao Zhang

International Journal of Vehicle Noise and Vibration Vol.15, No.2/3, 2019, p154-167 DOI: 10.1504/IJVNV.2019.106377

ABSTRACT: Bispectrum analysis is able to suppress the Gaussian noise and analyse quadratic phase coupling in the signals more accurately. However, traditional bispectrum has the problem of losing fault information at low frequency, and may not comprehensively refl ect nonlinear information of the fault, which leads to weak diagnostic ability, especially for local rub-impact fault. For this reason, a new feature extraction method called vector-bispectrum energy operator is presented in this paper, which adopts vector-bispectrum based on Teager energy operator and is used to obtain the fault feature of local rubbing rotor. The results of the experiment show that the feature of the local rubbing fault extracted by Teager energy operator based vector-bispectrum is very noticeable, and the fault classifi cation through SVM has a high recognition rate.

OIL-TREATED PLEATED FIBROUS AIR FILTERS FOR MOTOR VEHICLE ENGINE INTAKE APPLICATION

Ajay Kumar Maddineni et al


ABSTRACT: In this work, oil-treated pleated fi brous air fi lters were developed, characterized, and evaluated for motorcycle engine intake application. The eff ect of pleat geometry on the fi ltration performance was examined. Pleat pitch and pleat height were found to play important roles in determining the fi ltration effi ciency, pressure drop, and dust holding capacity. A pleated fi brous fi lter prepared with optimum levels of pleat pitch and pleat height showed the best fi ltration performance. The treatment to the pleated fi lter by viscous oil yielded remarkably higher dust holding capacity and fi ltration effi ciency, both at cleaned and clogged conditions. A statistical analysis revealed that the weight of oil played a signifi cant role in deciding the fi ltration performance. The oil-treated pleated fi lter was installed in a commercial air intake system and its fi ltration performance was assessed. The fi lter element displayed a signifi cant delay in evolution of pressure drop during dust loading as compared to the untreated one. However, the diff erence in fi ltration effi ciency between the oil-treated and untreated fi lter elements was not found to be too high. Nevertheless, both of them met the standard fi ltration performance as per the best practices followed by the automotive industry. Overall, the oil treatment to cellulosic fi lters was found to be highly advantageous for motorcycle application. Practical implications of such air fi lter system were discussed in terms of service life, fuel consumption, and CO2 emission during fi lter life time. (AUTH)

OPTIMAL DESIGN OF PASSENGER VEHICLE SEAT WITH THE USE OF NEGATIVE STIFFNESS ELEMENTS

Georgios Papaioannou et al


ABSTRACT: A seat that provides good vibration isolation is of prime importance for passenger’s safety and health. The main confl ict in seat suspensions implies that the increasing initial deformation of the system (increase in “static discomfort”) leads to better isolation of accelerations (increase in “dynamic comfort”). Many researchers have focused on overcoming or at least suppressing this confl ict between load support capacity and vibration isolation by modeling new suspension systems, such as the so-called negative suspension systems. However, apart from the modeling of new suspension systems, optimization is an important part in designing a seat and fi nding the best compromise between these two objectives. Thus, in this work, four types of seat suspension systems with embedded negative stiff ness elements are implemented and optimized in order to be benchmarked. Three of them have already been tested either in passenger or in an off -road vehicle seat. All the vibration isolators are optimized with genetic algorithms in respect to static and dynamic factors of ride comfort by applying constraints oriented to the objectives and the design of the structure. The optimization is implemented for two excitations, which correspond to a vehicle driving over road profi les of Classes A and B, and the common solutions are outlined. (AUTH)

A FULL EXPLICIT FINITE ELEMENT SIMULATION FOR THE STUDY OF INTERACTION BETWEEN WHEELSET AND SWITCH PANEL

C. Lu, et al


ABSTRACT: A full explicit FEM simulation of wheelset passing through switch panel is presented. The real 3D geometry of the switch panel is used, both vertical and lateral response are taken into consideration. The dynamic interaction is analysed and it is found that the damage mechanism on the switch blade and stock rail is a complex interaction of wear, fatigue and impact, which can be well described by explicit FEM simulation. Parametric analysis of running speed, traction coeffi cient and the friction coeffi cient between switch blade gauge surface and wheel fl ange indicate that decreasing running speed can help to reduce the damage on switch panel. The traction coeffi cient has little infl uence on the maximum impact response, but a higher traction coeffi cient is benefi cial for eliminating the dynamic response after the maximum impact response point. The infl uence of the friction coeffi cient on the dynamic impact response is not signifi cant, but a lower friction coeffi cient is favourable for decreasing the wear damage on the switch blade and increasing running safety. This work can provide a good understanding of the interaction on switch panel and give theoretical support for maintenance and improving the design. (AUTH)

International Journal of Crashworthiness Vol.25, No.1, 2020, p1-8 https://doi.org/10.1080/13588265.2018.1511232

ABSTRACT: Road accidents between cars and trucks have the highest fatal accidents ratio because of cars under running beneath trucks which leads to serious and fatal injuries for car’s occupants. The improper design of the underride guard system for trucks fails to prevent passengers of small vehicles from fatal injuries in collision with rear of heavy trucks. This research developed a new rear underride protection device for heavy trucks. Five design concepts are developed for the basic part of the underride guard device. Complex proportional assessment method was used to select the best design concept, while fi nite element analyses software ABAQUS was used to simulate and examine the structural behaviour of the underride guard (design A) comparing with the basic underride guard (design C). The simulation is specifi ed a termination time 0.2 sec, where simple rigid plate is used as impactor with speed of 63 km/h before hitting the underride guard assembly in the truck. The FMVSS 223/224 regulations were utilised to validate the developed underride guard. The results showed that design (A) achieved the goal of decreasing the acceleration to (15.83 g) beyond the limits (60 g), enhanced the energy absorption by 88.32%, and accomplished minimal passenger compartment intrusion.

CORRELATION ANALYSIS OF ROAD LOAD FUEL ECONOMY VARIATIONS BY ENERGY DIFFERENCE FOR GASOLINE DIRECT INJECTION AND DIESEL-POWERED VEHICLES

Jeonghun Son et al


TECHNICAL ABSTRACTS


ABSTRACT: Test fl exibilities, such as the tire pressure, adjustment of brakes, vehicle preconditioning, test mass, and running-in period, are multiple factors that can confound vehicle emissions and fuel economy tests. The road load force is the most infl uential fl exibility factor for a type-approval vehicle certifi cation test. Because of these various factors, it was revealed that there was a substantial diff erence between the type-approval emissions and those from a real-driving emissions test. In this study, the test cycle road load energy using the road load coeffi cients determined by the TA coast-down procedure was the base condition. After calculating the test cycle road load power, the constant term of the road load coeffi cient was adjusted by the energy loss. The tolerance of the road load in domestic regulation is 15%, so the constant term of the road load coeffi cient was increased by 5% in the cycle road load energy loss. Then, the road load power and tractive power were calculated from the force and vehicle speed. The vehicle fuel effi ciency, under the road load variation conditions, was determined for modern 2.4 L gasoline direct injection and lean NOx trap-equipped diesel vehicles on a chassis dynamometer. To assess the impact of diff erent road load values on the FE and carbon dioxide emissions, the test cycle was performed over the combined modes of the federal test procedure-75 and the highway fuel economy test. To investigate the road load variations of the vehicle fuel economy in correlation with the energy diff erence, the statistical approach of the one-way analysis of variance was applied. The results showed that the variations of the road load energy of the tested cycle were closely related in a trade-off relationship with the vehicle fuel economy. (AUTH)

INCREASING FUEL ECONOMY OF COMMERCIAL TRANSPORT BY USING A HYBRID POWER TRAIN

E.S. Meltsyn and A.A. Markina


ABSTRACT: Undoubtedly, the issue of increasing the fuel economy of passenger commercial vehicles is one of the most important, since the annual increase in the cost of fuel leads to an increase in the fi xed costs of not only transport companies, but also small and medium-sized businesses. Using a hybrid power train (HPT) can reduce fuel consumption in the urban cycle, which is important for commercial vehicles used to deliver goods and passengers

within the city, especially when it comes to megacities where traffi c is diffi cult and average speeds are not high. Unfortunately, the cost of cars with a HPT, such as Toyota Prius, Lexus RX 450H, Ford Fusion Hybrid and others, remains quite high and cannot be fully compensated just at the expense of fuel economy.

EXPERIMENTAL INVESTIGATION INTO SIMULATED AGING EFFECTS OF COMMON-RAIL INJECTOR NOZZLES: INFLUENCES ON INJECTION RATE, SPRAY CHARACTERISTICS, AND ENGINE PERFORMANCE

Sebastian Schuckert et al


ABSTRACT: Emission performance of combustion engines has gained outstanding importance with both legislators and customers over the past years. Injector aging, such as nozzle wear or coking, results in the deterioration of injection and emission parameters. In this study, the infl uences of aging eff ects on injection rate, fuel spray as well as engine performance and emissions were assessed. Nozzles, which had previously been operated in a vehicle engine and were likely to have suff ered from aging, showed no aging-induced characteristics during injection rate and spray measurements and were not investigated further. Therefore, nozzles with diff erent nozzle hole diameters were utilized to simulate the diff erent aging eff ects. Injection rate measurements demonstrated, that for smaller energizing times, a nozzle with smaller nozzle holes can deliver a higher injected mass than a nozzle with bigger nozzle holes. The adaptation of energizing time or injection pressure demonstrated the potential to compensate the change in engine load due to smaller or bigger nozzle holes. For bigger nozzle holes, the adaptation of injection pressure in order to restore the target load returned lower NOx emissions, whereas the adaptation of the energizing time always yielded lower soot emissions compared to the reference nozzle. For small nozzle holes, the optimization of the start of energizing reduced specifi c NOx emissions without increasing specifi c soot emissions. The comparison of measured injection rate and fuel spray characteristics to the ones reported in literature confi rms the possibility of simulating nozzle wear by increased nozzle holes and coking by smaller nozzle holes. The results of this study are of vital interest to the research of aging eff ects and add useful knowledge about compensation methods for nozzle aging. (AUTH)

FUEL CONSUMPTION REDUCTION BY INTRODUCING BEST-MODE CONTROLLER FOR HYBRID ELECTRIC VEHICLES

ABSTRACT: In this paper, a power management system for hybrid electric vehicles is developed and shown to improve the vehicle fuel consumption in various working conditions. A best-mode concept is defi ned based on the results of the dynamic programming global optimization strategy. It is shown that the use of exclusive control relations for each working mode improves fuel saving. The working state of the engine and one electric motor is used to determine the best-mode of powertrain operation. The best-mode classifi cation also considers the battery state of charge. This enables the controller to specify near optimal working points in a wide range of state of charge. The control rule for each diff erent work-mode is developed based on the dynamic programming results and applying the particle swarm optimization algorithm. The results show that the best-mode controller is capable of achieving fuel consumptions around 97% of that of the offl ine dynamic programming. (AUTH)

ABSTRACT: Oil liquid sloshing is a normal physical phenomenon in fuel tank under variable conditions of

vehicles. Installing baffl es in fuel tank is an eff ective method to suppress oil liquid sloshing. The infl uence of diff erent baffl e shapes on the pressure of oil liquid sloshing and time-area value is the focus of this work. Four factors infl uencing the baffl e shape and baffl es of six diff erent shapes are provided in this research. The pressure history curves of oil liquid sloshing at the central point and on the central line, the history curves of velocity of oil liquid mass and volume, oil liquid pressure contours, and the position diagrams of free oil liquid surface were obtained and compared in fuel tanks with baffl es of diff erent shapes. Compared with the sloshing pressure of oil liquid and time-area values in fuel tanks with baffl es of diff erent shapes, the sloshing pressure of oil liquid at the central point is the smallest in fuel tank with baffl es of corrugated shape, and the sloshing pressure of oil liquid on the central line is the smallest in fuel tank with baffl es of straight-line shape. However, the baffl es of corrugated shape are most benefi cial to reduce time-area values. (AUTH)

A SELF-ADAPTIVE ENERGY ABSORBER FOR IMPROVED PEDESTRIAN SAFETY AND LOW-SPEED DAMAGE REQUIREMENTS

James Wu et al


ABSTRACT: Bumper performance under low-speed impacts and pedestrian-to-vehicle impacts are regulated in the United States by Regulation Part 581 and ECE 127/GTR 9, respectively. These regulations possess a contradictory set of requirements. An ideal bumper structure should be stiff for the former scenario while exhibiting a softer response for the latter. Several energyabsorbing structures capable of passively adapting their mechanical responses were investigated using fi nite element modelling with complementary validation tests. The preferred structure consisted of a rectangular array of trapezoidal cells which buckle under single-cell impacts while resisting lateral deformation and increasing the structural stiff ness under large-area impacts. A geometric study of this dissipater demonstrated the potential to increase total energy absorption by 37.3% by adding crossbars between adjacent cells. Additionally, a parametric study identifi ed the upper cell angle and the ratio between wall thicknesses as critical

ABSTRACT: In this work the composite material shaft in high-speed rotor-bearing systems is analysed to achieve better rotor dynamics along with the eff ect of internal damping of the composite shaft. The pioneering studies on rotating composite shaft and internal damping are revisited to evaluate its eff ects on rotor dynamics of high-speed rotor-bearing systems. Two practical rotor-bearing systems are selected to study their suitability for composite shaft application where the composite material is used in the cold section while the existing steel alloy is retained in the hot section as well as at the ends. The rotor dynamic analysis shows signifi cant improvements in rotor dynamics of one of the rotor-bearing systems where the fi rst lateral mode changes to desirable rigid mode from fl exure mode shape of existing metallic shaft rotor-bearing system. The frequency values of second and third modes also increase above the operating speed indicating a clear advantage in rotor dynamics. (AUTH)

LAYER-WISE DAMAGE PREDICTION IN CARBON/KEVLAR/S-GLASS/E-GLASS FIBRE REINFORCED EPOXY HYBRID COMPOSITES UNDER LOW-VELOCITY IMPACT LOADING USING ADVANCED 3D COMPUTED TOMOGRAPHY

A. Vasudevan et al


ABSTRACT: Examination of stacking sequence eff ect is essential in optimising the properties of synthetic fi bre reinforced hybrid polymer composites for protecting the aircraft structure from the barely visible impact damage during low-velocity impact (LVI) events. It is important to know the quasi-static mechanical properties of polymer composites before analysing the LVI damage. Therefore, in this study, both quasi-static mechanical (tensile, fl exural and punch-shear) and LVI properties of epoxy reinforced woven roving, E-glass and three diff erent interply hybrid fabric (S-glass-E-glass, Carbon-E-glass and Kevlar-E-glass) composites are investigated. In all these hybrid composites, E-glass fabric layers are placed in the interior. Analysis of LVI properties indicated a 7.5% increase in the maximum energy absorption for laminates having Kevlar fi bre as surface layers as against 3.4% decrease in energy absorption and 13.5% for laminates with carbon fi bre and S-glass fi bre as surface layers, respectively, compared to the E-glass/epoxy composite. An X-ray computed tomography is used for observing the layer-wise damage mechanisms of the LVI tested specimens from damage initiation to fi nal perforation, which predicts that the bottommost layers of the plate are subjected to more damage. The damage area for each layer of the composite plates are measured using Image J software. Carbon-E-glass/epoxy composites are found to have more damage area than the other laminates. The delamination and damage zone of the plates are detected using the ultrasonic C-scan. The scanning electron microscopy is used to examine the fractured surfaces of tensile, fl exural and punch-shear tested specimens. (AUTH)

semi-rigid barrier and satisfi ed the target performance when it, into which the initial pre-stressed force of 1900 kN was introduced, employed strong posts with a post spacing of 60 m. The occupant safety of this semi-rigid cable barrier is improved when the post spacing is increased but the initial pre-stressed force of the cables and cable anchor systems had to be increased to maintain the same working width. Due to the fl exible characteristics of cable barriers with long spans, the semi-rigid cable barrier showed a possibility that it could accommodate small car impact velocities higher than 160 km/h. However, the semi-rigid cable barrier also revealed a vulnerability for large vehicle impacts as its bottom rail might rotate if the installation height was not enough to accommodate the defl ection of cables. The fi nal design of the long-span strong-post semi-rigid cable barrier was verifi ed through full-scale vehicle crash tests. (AUTH)

ABSTRACT: The sound level inside an automobile cabin plays a major role in the passengers’ comfort. Active noise control has been widely used to reduce the sound level inside the car cabin. This article presents a design of an active and robust sound control system that can still be effi cient despite the changes inside the passengers’ compartment caused by the movement of the occupants. Initially, the coupled acoustic structural analysis is done on a simplifi ed model of an automobile cabin by using fi nite element and modal coupling methods. Then, the uncertainty of the sound fi eld inside the car, due to the presence of the occupants and the displacement of their heads, is investigated. A multi input multi output robust feedback control strategy, using the H∞ method and considering the unstructured uncertainty of the acoustic structural system, is proposed to reduce the sound pressure level at the ears of all the occupants. In order to achieve performance targets in a broad bandwidth and to reduce the waterbed eff ect, an optimization is performed on the weight function coeffi cients. The results show that in the frequency range of 0–334 Hz, the controller has an acceptable performance which is robust to changes in the interior sound fi eld. (AUTH)

AN IMPROVED NARROWBAND ACTIVE NOISE CONTROL SYSTEM WITHOUT SECONDARY PATH MODELLING BASED ON THE TIME DOMAIN

Kuheli Mondal et al


ABSTRACT: Several secondary path, acoustic noise cancellation modelling causes the problems to increase the complexity of ANC implementation, reduction of performance caused by modelling error and requirement of auxiliary noise for secondary path modelling. The acoustic noise generated is further compounded by using secondary path identifi cation which makes the system complex. There are several available ANC algorithms that do not require secondary path estimation for modifying the FxLMS algorithms. Due to drawbacks such as slow convergence speed and, complexity of the phase shift mechanism, a novel approach with no secondary path modelling is adopted, in which the adaptation stability is guaranteed by switching the sign of the step size. It is combined with the online tuneable delay of the reference signal to signifi cantly improve the adaptation convergence properties of the algorithm. A new mathematical modelling has been proposed to reduce the acoustic noise that increases the convergence criteria. (AUTH)

ABSTRACT: Various vibration isolators using negative stiff ness elements have been proposed in order to improve ride comfort of passengers in vehicles. In this paper, fi ve diff erent ones are compared. Four of them have been already propped, while the fi fth one is novel, based on the KDamping concept, which has proven effi cient in other applications. After optimising each one with respect to static

and dynamic factors of ride comfort, three types of analysis are performed. In the fi rst type, the models are simulated for the optimum solutions, for two more excitations which correspond to the response of the vehicle’s body while driving over road profi les of Class B and C. In the second type, the models are simulated for diff erent seated passengers. While in the third type, based on the Pareto theory, three solutions are fi nally selected for each model, and their transmissibility from seat to head (STHT) is compared. The main conclusion is that the isolator using the KDamping concept has proven its adaptability and universality for diff erent excitations corresponding to diff erent road classes and for diff erent seated passengers, minimising the resonance frequency around 0.56 Hz and providing the most compact and comfortable optimum design solutions among all the other models.

EFFECT OF CAR SPEED ON THE TRANSMISSION OF VIBRATION THROUGH THE SEAT PAN AND BACKREST: FIELD STUDY

Said Grami et al


ABSTRACT: This study investigates the eff ect of car speed on the vibration transmitted to the passenger through both the seat pan and backrest. Ten male subjects sat in the front passenger seat of a sedan car and were driven at three diff erent speeds (60, 80 and 100 km/h). During each ride, the vibration dose value (VDV) was measured in the x, y and z-directions on the seat pan and at the backrest. The results showed an increase in the VDV in all directions with increasing the car speed. The VDVs at the backrest were found as high as, or even higher than, those measured on the seat depending on the speed and the measurement axis. Hence, it is recommended that vibration in road vehicles be assessed using more than one speed while taking into consideration measurement at the backrest. (AUTH)

EVALUATION OF VIBRATION CHARACTERISTICS OF PARTIALLY CRACKED SYMMETRIC LAMINATED ORTHOTROPIC HYBRID COMPOSITE PLATES

Ajay Kumar Verma et al


ABSTRACT: The present study is a numerical investigation on the vibration and defl ection characteristics of an industry-driven carbon-boron/epoxy hybrid laminated composite plate that is partially cracked. The eff ect of laminated stacking sequence, volume fraction and crack length on natural frequency are investigated. The study is carried out using analytical methods, such as classical laminated theory, fi nite element analysis (FEA) and artifi cial neural network (ANN) for trained sets. Validation and comparison of the present work has been made with the work by Khdeir and Librescu on analysis of symmetric cross-ply laminated elastic plates using a higher-order theory, in which buckling and free vibration were considered. In this study, the CCSS boundary condition is used. A very good agreement has been observed between the analytical and FEA results. The concept of mechanical behaviour is introduced to address both the natural frequency and defl ection criteria, with which a design guideline for robust hybrid composites is given. (AUTH)

INVESTIGATION OF FRICTION-INDUCED VIBRATION IN A DISK BRAKE MODEL, INCLUDING MODE-COUPLING AND GYROSCOPIC MECHANISMS

ABSTRACT: The brake squeal reduction has been extensively investigated in many academic and industrial researchers. Friction-induced vibrations can be considered as a dynamic instability problem. Generally, automotive engineers and researchers working in the domain of disk brake noise treat instabilities due to the force of friction as a friction-induced vibration. In the case of squeal noise, mode

coupling may cause instability of the system. The aim of this article is to propose a minimal two degree of freedom disk brake model in order to investigate the eff ects of diff erent parameters on mode-coupling instability. This model takes into account self-excited vibration, gyroscopic eff ect, friction-induced damping, and brake pad geometry. Thus, a stability analysis of equilibrium by calculating complex eigenvalues is presented to investigate the infl uence of the main parameters on the stability zone such as the opening angle of the brake pad and preload. For the validation of the stability analysis, squeal index and time domain response are used. The results obtained show the importance of optimizing the physical and geometrical parameters of the brake and that some of these parameters have greater eff ects compared to the others to reduce noise.

VARIABLE FREQUENCY DRIVE HARMONICS AND INTERHARMONICS EXCITING AXLE TORSIONAL VIBRATION RESULTING IN RAILWAY WHEEL POLYGONISATION

U. Spangenberg


ABSTRACT: Severe vibrations and an increase in structural component fatigue failures have been observed on a freight locomotive class operating on a heavy haul route within South Africa. The root cause of these severe vibrations were investigated experimentally and it was found that polygonised wheels were cuasing these severe vibrations. A coupled mode of vibration exists in the traction system that is a combination of traction motor pitching and wheelset axle torsion. Harmonics and interharmonics are features of an AC motor controlled by a variable frequency drive (VFD) and were confi rmed to cause resonance of the coupled vibration mode. Interharmonics are a function of the fundamental frequency (fm) of the VFD and the input AC frequency (fg) supplied to the VFD. It was found by experimentation that the 5fg−7fm interharmonic caused resonance of the coupled mode while the locomotive operated at 40 km/h. This running speed and frequency of vibration was found to fi x the wavelength of a 20th order polygon on the wheels during approximately 11% of the locomotive’s load hauling time. (AUTH)

VIBRATION SOURCE IDENTIFICATION OF A HEAVY COMMERCIAL VEHICLE CAB BASED ON OPERATIONAL TRANSFER PATH ANALYSIS

Zhiyong Zhang et al


ABSTRACT: Operational transfer path analysis is applied in this study to identify the vibration source and its critical transfer path. A simple analytical fi ve-degrees-of-freedom mechanical isolation system is fi rst taken as an example to illustrate the analysis fl ow and to validate the accuracy of operational transfer path analysis. The acceleration amplitude spectrum of the receiver is used to prove the accuracy, and the path contribution of each path is used to identify the critical path. Operational transfer path analysis is then applied to the cab mount system of a heavy commercial vehicle to identify the vibration source and its critical transfer path. The vibration energy propagation capabilities from the four cab mounts to the driver’s seat are analyzed by operational transfer path analysis with the path contribution analysis, and the maximum vibration source is identifi ed by the path operation contribution analysis. The analysis and evaluation method of the operational transfer path analysis introduced in this study can provide a research foundation and reference for vibration or noise source identifi cation in mechanical systems.

VIBRATION TESTING OF VEHICLE COMPONENTS BY FATIGUE DAMAGE SPECTRUM CONTROL

ABSTRACT: Random vibration testing with increased kurtosis introduces high peaks into shaker drive signals to simulate land vehicle vibration more accurately or to shorten duration of fatigue damage testing. For the latter, the kurtosis control method must be able to pass high kurtosis values from the generated shaker vibration into the stress response of the tested component. It was verifi ed

and confi rmed in the paper that the method of phase manipulation based on the analytical relationship between the IFFT phases and kurtosis was capable of doing so if the resonance frequency of the component is known. However, the fatigue damage spectrum model used for evaluation of time-to-failure considers not just one but a number of resonance frequencies constituting a certain test profi le which cannot be simulated by the kurtosis control alone. For this purpose, the phase manipulation method was developed further and verifi ed for operational vibrations of a railway vehicle. (AUTH)

DYNAMIC PARAMETERS OPTIMIZATION OF STRADDLE-TYPE MONORAIL VEHICLES BASED MULTIOBJECTIVE COLLABORATIVE OPTIMIZATION ALGORITHM

Junchao Zhou et al


ABSTRACT: The dynamic parameters of Straddle-type monorail vehicles with single-axle bogies are optimised by utilising the multi-body dynamic method. The dynamic parameter optimisation is conducted aiming at the curve negotiation properties, comfort and tire eccentric wear of monorail vehicles. The optimisation model is established with software ADAMS and modeFRONTIER and the Sobol is adopted for sensitivity analysis to acquire the optimised parameters. Finally, the multiobjective collaborative optimisation algorithm is utilised for optimised analysis. According to the results, the proposed method can conduct multi-objective optimisation to the monorail vehicles in a successful way. The curve negotiation properties and comfort are improved, and the tire wear is reduced with dynamic parameters after optimisation. Especially, a conversion strategy of the consistent objective function is proposed aiming at multiobjective nonlinear convergence. (AUTH)

CRASHWORTHINESS ANALYSIS OF AN AIRCRAFT FUSELAGE SECTION WITH AN AUXILIARY FUEL TANK USING A HYBRID MULTIBODY/PLASTIC HINGE APPROACH

Yi Yang Tay et al


ABSTRACT: The drop test of a Boeing-737 fuselage section is modelled using a multibody (MB) with spatial plastic hinge method. The test is simulated in MADYMO to evaluate the structural interaction of the cabin with a stiff auxiliary fuel tank underneath the fl oor, in a severe but survivable impact condition. The fuselage ribs, cargo door frame, cargo door, and passenger fl oor with spar webs are modelled using a large number of bodies and universal joints with directional properties to allow for appropriate torsional and bending deformations. The contacts for the fuselage section are modelled using a Hertzian-based contact force model with dissipative damping. The simulation results from the MB approach show reasonably good agreement with those from the experimental test and from a detailed fi nite element (FE) model. This MB approach then could be a viable tool in modelling occupant and structural deformations for aircraft crashworthiness problems. (AUTH)

NUMERICAL PREDICTION AND EXPERIMENT OF IMPACT ON RUBBER HYDRO UNIT WITH MULTI-CHAMBERS USING AN EFFECTIVE DYNAMIC CO-SIMULATION APPROACH

Robert Keqi Luo


ABSTRACT: An accurate evaluation on dynamic impact response for rubber–metal components with fl uid has been very challenging over many years, especially using three-dimensional dynamic co-simulation via fl uid-structural-interaction (FSI) in time domain. There are also very limited successful cases reported on dynamic impact evaluation in vehicle applications. Natural frequency region (NFR) approach, based on computational solid dynamics, recently proposed by the author, has successfully evaluated dynamic response of rubber anti-vibration components without fl uid. This method is extended to fl uid using co-simulation with computational fl uid dynamics (CFD). This combined approach, i.e. NFR–FSI–CFD approach, is applied to an impact simulation on a joint unit including two solid rubber springs and one shock mount with two pistons embedded in internal fl uid chambers. The result of the simulation is validated with the experimental data. Eight key aspects are identifi ed and main steps to eff ectively perform dynamic co-simulation are suggested. This proposed approach is designed for industrial practice to simulate rubber hydro anti-vibration systems as the detailed deformation and strain/stress profi les of the components can be obtained. The real stiff ness of the anti-vibration system can be calculated from the load-defl ection curve generated and employed for vehicle system dynamics. (AUTH)

RAPID ROAD FRICTION ESTIMATION USING INDEPENDENT LEFT/RIGHT STEERING TORQUE MEASUREMENTS

Craig E. Beal


ABSTRACT: Sensing the friction coeffi cient between the tyres of an automobile and the road surface is a key challenge in automotive control. Accurate estimation of this parameter enables higher performance and safer operation of vehicles, whether human-operated, assisted or autonomously controlled. Previous approaches have utilised braking or lateral excitation to generate estimates but are limited by the confl ict between generating suffi cient excitation and preserving ride comfort and effi cient operation. Further complicating the problem is the need to provide the friction estimate without adding costly sensors to the vehicle. This paper presents an approach to friction estimation that leverages separate measurements of the left and right steering torques to generate an estimate of the surface friction through direct model inversion. Uncertainty of the method is explored using experimental sensor properties and analysis of the inverted model. The method is shown to be sensitive to reduced friction coeffi cients and can identify sudden changes before travelling a full contact patch length. Experimental validation of the approach is demonstrated with calibrated wheel force transducers as well as low-cost sensors suitable for incorporation into production vehicles. (AUTH)

ABSTRACT: To improve vehicle handling performance,

TECHNICAL ABSTRACTS


a variable steering ratio characteristic for steer-by-wire system is designed. The steering ratio is adjusted by a compensating coeffi cient according to vehicle longitudinal speed and steering wheel angle. To evaluate the performance of vehicle with variable steering ratio, simulations are conducted based on an objective evaluation index, which consists of quadratic cost functions of vehicle lateral deviation, steering angular speed, vehicle lateral acceleration and roll angle. By using the optimized data from the simulation results, a Takagi-Sugeno fuzzy neural network is designed for the steering ratio control. In order to test and validate the proposed controller, a series of comparison experiments are conducted on a closed-loop driver-vehicle system, including lemniscate curve test and double lane-change test. The results demonstrate that compared with a conventional steering system with fi xed steering ratio, the proposed system can not only improve steering agility at low speed and steering stability at high speed, but also reduce driver’s workload in critical driving conditions.

YAW AND LATERAL STABILITY CONTROL FOR FOUR-WHEEL-INDEPENDENT STEERING AND FOUR-WHEEL-INDEPENDENT DRIVING ELECTRIC VEHICLE

Chunyan Wang et al


ABSTRACT: Based on the traditional four-wheel steering system, this paper combines the steer-by-wire system and four-wheel-independent driving technology to develop a new steer-by-wire four-wheel-independent steering and four-wheel-independent driving electric vehicle, which can realize four-wheel-independent steering and four-wheel-independent driving. Aiming at the steering actuator redundancy characteristics of the four-wheel-independent steering and four-wheel-independent driving vehicle, a hierarchical control method is proposed in this paper. In view of parameters perturbation of vehicle speed and tire cornering stiff ness and the model uncertainty problem, the structure singular value μ is used to study the stability control of four-wheel-independent steering and four-wheel-independent driving vehicle under multiple perturbations in the upper layer, and verifi es the advantages of μ controller by comparing it with H∞ control and proportional-integral-derivative control. The lower layer is aimed at the redundancy

of vehicle steering actuator, an on-line reconfi gurable steering angle and driving force allocation control method based on tire force optimal allocation is proposed. This method can not only optimize the tire longitudinal force and lateral force distribution under normal conditions but also reconstruct the distribution control strategy on-line under fault conditions, realizing active fault tolerance. Finally, simulations by MATLAB/Simulink and hardware-in-the-loop experiments are conducted to verify the proposed control method. The simulation results show that the designed controller can maintain good stability under the conditions of model perturbation, separation pavement, and actuator failure. (AUTH)

USING AN INERTER-BASED SUSPENSION TO IMPROVE BOTH PASSENGER COMFORT AND TRACK WEAR IN RAILWAY VEHICLES

T. D. Lewis, et al


ABSTRACT: There is an increasing desire in the railway industry to improve the longevity of wheels and rails without reducing performance in other ways (e.g. worsening passenger comfort). One way of reducing track and wheel wear is to reduce the primary yaw stiff ness, signifi cantly diminishing the costs associated with maintenance and emergency repairs, resulting however in reduced passenger comfort and high-speed stability. This paper, using a two-axle railway vehicle case study, demonstrates the potential of using passive, inerter-based suspensions to concurrently improve ride comfort and reduce track wear. The industrial parameter Tγ is used to quantify the frictional energy lost at the contact patch under curving conditions, and the lateral RMS carbody acceleration is used to quantify passenger comfort under straight running conditions, with lateral track disturbances taken from real track data. Optimisation results conclude that, with the default yaw stiff ness value, compared with the default spring-damper confi guration in the primary lateral suspension, employing benefi cial inerter-based confi gurations can improve passenger comfort by up to 43%. If the yaw stiff ness is reduced such that the track wear is improved, similar improvements in passenger comfort can still be achieved with lateral inerter-based

suspensions; for example, an improvement of 33% can still be achieved with a 50% reduction in yaw stiff ness. Furthermore, when an inerter-based lateral suspension is used together with a Hall-Bush longitudinal suspension, the passenger comfort rises to 40%, which relates to a 25% improvement when compared with a non-inerter lateral plus Hall-Bush longitudinal setup.

COMBINED ACTIVE SUSPENSION AND STRUCTURAL DAMPING CONTROL FOR SUPPRESSION OF FLEXIBLE BODIED RAILWAY VEHICLE VIBRATION

Xiang Zheng et al


ABSTRACT: The design trend for future high-speed trains is envisaged to be lightweight, rising the cost of structural vibration due to the extra fl exibility. In this context, studies have looked into the suppression of such vibrations via the use of either (conventional actuators) active suspensions or by structural damping via piezoelectric actuators. The addition of extra macro-actuators will highly impact vehicle weight and is subject to location constraints, while the use of only piezo-actuators normally does not reach the required force levels for appropriate suppression. However, piezo-actuators provide appropriate complementary action with conventional active suspension. In this paper, we present a decentralised control scheme for suppressing the vertical vibration of the vehicle body, combining active structural damping via frequency-weighted H2 control and active suspension control using skyhook damping via structured H∞ synthesis. A vertical side-view model of a fl exible-bodied railway vehicle is used for the control study, with the confi guration of piezoelectric actuators and sensors determined via structural norms. Stability robustness of the controller is analysed with respect to parametric and dynamic uncertainties using μ analysis techniques. Results illustrate the eff ectiveness of the proposed control scheme for both fl exible and rigid modes while guaranteeing robustness to model uncertainty. (AUTH)

FUZZY SLIDING MODE BASED ACTIVE DISTURBANCE REJECTION CONTROL FOR ACTIVE SUSPENSION SYSTEM

Haoping Wang et al


ABSTRACT: This article deals with the control problem of 7-degrees of freedom full-car suspension system which takes into account the spring-damper nonlinearities, unmodeled dynamics and external disturbances. The existing active disturbance rejection control uses an extended state observer to estimate the “total disturbance” and eliminate it with state error feedback. In this article, a new type of active disturbance rejection control is developed to improve the ride comfort of full car suspension systems taking into account the suspension nonlinearities and actuator saturation. The proposed controller combines active disturbance rejection control and fuzzy sliding mode control and is called Fuzzy Sliding Mode active disturbance rejection control. To validate the system mathematical model and analyze the controller performance, a virtual prototype is built in Adams. The simulation results demonstrate better performance of Fuzzy Sliding Mode active disturbance rejection control compared to the existing active disturbance rejection control. (AUTH)

Finally, the vehicle on-road test is conducted to experimentally validate the proposed models. Both analytical and experimental results indicate that the vehicle fi tted with hydraulically interconnected suspension and electronic controlled air spring can obtain high performance for both handling stability and ride comfort.

MODE CONTROL OF ELECTRO-MECHANICAL SUSPENSION SYSTEMS FOR VEHICLE HEIGHT, LEVELLING AND RIDE COMFORT

Baek-soon Kwon et al


ABSTRACT: This paper proposes a mode control algorithm of electro-mechanical suspension for vehicle height, attitude control and improvement of ride quality. The proposed control algorithm consists of mode selector, upper-level and lower-level controllers, and suspension state estimator. The mode selector determines the present driving mode using vehicle signals, such as longitudinal speed, steering wheel angle, accelerator pedal position, brake pedal position and vertical acceleration of wheels. The upper-level controller determines the desired suspension state using the present driving mode. The lower-level controller derives the desired stroke speed of the actuator in each suspension by linear quadratic control theory. The suspension state estimator has been designed using accessible sensor measurement by discrete-time Kalman fi lter theory. The control and estimation algorithms have been developed based on a novel reduced-order vehicle model that includes only the vehicle body dynamics. The model enables the observer to completely remove the eff ect of unknown road disturbance on the estimation error. The performance of the proposed control algorithm has been evaluated via computer simulation study. The simulation results show that the proposed control algorithm is eff ective at controlling the electro-mechanical suspension systems. The paper also shows that the considered actuator is suited for vehicle height and levelling control, but not for improvement of ride comfort, due to voltage input constraints. (AUTH)

MINIMIZING SYNCHRONIZATION TIME OF A GEAR SHIFTING MECHANISM BY OPTIMIZING ITS STRUCTURAL DESIGN PARAMETERS

Muhammad Irfan et al


ABSTRACT: A gear shifting mechanism is modeled in GT-Suite software. The mechanism has three main bodies: sleeve, ring, and gear. Results obtained from the simulation show that GT-Suite model can predict gear shifting process. Synchronization processes for three conditions of nominal, road grade, and vibrational motion of the master are studied in six cases by considering the sleeve and the gear as a master alternatively. The optimization based on the GT-Suite model is performed for each case to fi nd the minimum gear shifting time based on variations of 17 structural design parameters. Minimum synchronization time is found almost same in all cases. It is concluded from closeness of the optimization results that average of the parameter values can be considered as optimized values for all cases. At the end, robustness of the optimized structural design parameters are analyzed with respect to the road grade, amplitude, and frequency of oscillatory excitation of rotational motion of the master.

and improve the driving comfort simultaneously. Dynamic programming with a varying weighting factor in the cost function is proposed to balance the shift frequency and the fuel consumption for the power-split control and gear schedule design. Simulation results present that the drivability can be improved with a varying weighting factor due to fewer shift events while the fuel consumption is only slightly increased compared to dynamic programming with a constant weighting factor. A shift-energy-management strategy integrating the upshift and power-split control based on a multi-objective optimization is presented where model predictive control is employed to ensure engine load rate constraints. The strategy can smoothen the engine torque through torque compensation from the electric motor to prevent engine transient emissions resulting from a sudden load change. In a simulation study, the NOx and HC emissions could be reduced by 1.4% and 2.6% with 2% increase of the overall fuel consumption for the Federal Test Procedure 75 by smoothening the engine torque. For the New European Driving Cycle, 0.9% and 1.1% reduction of NOx and HC emissions could be achieved with only 0.3% more fuel consumption. (AUTH)

REAL-TIME IDENTIFICATION OF DRY-CLUTCH FRICTIONAL TORQUE IN AUTOMATED TRANSMISSIONS AT LAUNCH CONDITION

Mojtaba Sharifzadeh et al


ABSTRACT: In this work, a new methodology for online identifi cation of the dry-clutch torque characteristics model in vehicular transmission systems is presented. The proposed approach provides a tool with capability to estimate the clutch torque model parameters directly, using the measurable signals of engine torque and speed within a multiple model predictive control loop, in real time. The fi rst step is to calculate the clutch torque which includes some degree of uncertainty. Then, it is presented an advanced identifi cation approach which is based on trust region and has enough robustness to cover the uncertainty of calculated torque. The structure aims to ensuring a comfortable clutch lock-up by keeping reasonable engagement period and avoiding engine stall. Real-time model simulations in various conditions are also presented to illustrate the superior performance and to demonstrate the eff ectiveness of the algorithm. The identifi cation method has also been tested on real vehicle equipped with 1.3 L turbocharged diesel engine and six-speed automated manual transmission. Diff erent launch maneuvers have been considered to demonstrate the methodology and promising results have been achieved. (AUTH)

Peter Tawadros et al


ABSTRACT: This paper presents the use and development of a specifi c wireless torque measurement system that is used to obtain the transient torque performance of vehicle transmissions. The torque sensor is strain-based, using surface-mounted strain gauges on a prop shaft. The gauges are connected to a compact printed circuit board, which is clamped to the shaft next to the strain gauges using a three-dimensional printed housing. The printed circuit board contains an amplifi er, low-pass fi lter, analog-to-digital converter, microcontroller and bluetooth transceiver. The printed housing is impact resistant carbon-reinforced nylon and securely retains the printed circuit board and the battery powering the device. The transmitted torque data are received by a transceiver, which is interfaced to a PC through an RS-232 connection. NI LabVIEW is used to process, display and save data. The wireless torque sensor was installed to the Unit Under Test at the output shaft of the fi ve-speed manual transmission. The Unit Under Test was installed on a dynamometer for verifi cation purposes and the transient torque was recorded under various operational conditions. The transient output torque of the manual transmission is measured and compared with results obtained from simulations performed under similar operating conditions. The two sets of transient responses show a good correlation with each other and hence demonstrate that the torque sensor meets the major design

IMPACT OF THE WASTEGATE OPENING ON RADIAL TURBINE PERFORMANCE UNDER STEADY AND PULSATING FLOW CONDITIONS

Ahmed Ketata et al


ABSTRACT: The present article attempts to describe the behavior of wastegated turbines under various steady and pulsating fl ow conditions. For this, meanline and one-dimensional numerical codes including appropriate modeling approaches for wastegated turbines have been developed with the FORTRAN language. These codes were validated against experiments with an established test rig at the National School of Engineers of Sfax. The discharge coeffi cient map of the wastegate was determined with a developed correlation built from experiments, and it was served as an input to the developed codes for interpolations during computation. This correlation is based on a two-dimensional non-linear dose-response fi tting relationship instead of classical polynomial function which is one novelty of the article in addition to the one-dimensional modeling methodology. The normalized root mean square error (NRMSE) of both cycle-averaged effi ciency and mass fl ow parameter (MFP) remains below 2% which confi rms the validity of the proposed calculation approach. The results indicated a large deviation in the turbine performance under pulsating fl ow conditions compared to the steady state ones. The shape of the hysteresis loop of the turbine effi ciency remains unchanged toward the variation of the wastegate valve angle at the same pulse frequency. The mass fl ow hystereses loop area is decreased by around 50% as the pulse frequency increases from 33 up to 133.33 Hz. An increase of less than 1% of the cycle-averaged effi ciency has been reported when the bypass fl ow through the wastegate increases. The fl uctuation of the effi ciency is decreased by 1.5% when the wastegate valve becomes fully opened under the whole range of the pulse frequency. (AUTH)

DYNAMIC MODELING AND EXPERIMENTAL VALIDATION OF SKID-STEERED WHEELED VEHICLES WITH LOW-PRESSURE PNEUMATIC TIRES ON SOFT TERRAIN

Shouxing Tang et al


ABSTRACT: Wheeled skid-steered technology has an increasing interest in its use for off -road unmanned ground vehicles, because of its great mobility and compact mechanical structure. By integrating multibody dynamics model and semi-empirical tire-terrain model, this paper presents a dynamic modeling approach for skid-steered wheeled vehicles with low-pressure pneumatic tires on soft terrain to predict and investigate its steering performance. The forward dynamics equations are built by spatial vector algebra. The tire–terrain model estimates fl exible deformation and sinkage of the tire, and calculates forces and torques exerted on the tire according to relative motions of tire–terrain contact. The combined longitudinal slip and lateral skid of tires, and the vertical coupled deformations of tires and terrain are also considered in tire-terrain model. This approach optimizes the solution procedure and improves the computing effi ciency. The simulation results show that the proposed tire–terrain model can predict the eff ects of rigid and fl exible operation modes of tires on mechanical properties of tires and steering performances of the vehicle. The proposed dynamic model is validated on a six-wheeled skid-steered vehicle. The comparisons between experimental results and simulations show that the proposed dynamic model provides a better accuracy of steering performance simulation for skid-steered vehicles. (AUTH)

MULTI-CHAMBER TYRE DESIGNING FOR FUEL ECONOMY

Hamad Sarhan Aldhufairi et al


ABSTRACT: Rolling resistance plays a major role in tyre development due to its signifi cant infl uence on energy consumption and environmental impact. Numerous eff orts to minimise the tyre’s rolling resistance have met with no or minor success because of the tyre’s complexity and the involved compromises. This paper explores a novel design solution of the multi-chamber tyre, as a potential alternative, for low rolling resistance while meeting other driving requirements – a multi-purpose generalised solution (design-for-all). A novel multi-chamber design (base design) with a validated fi nite element model was used to create the diff erent novel designs. Statistical analysis based on the design of experiment was conducted to identify the best cavity volumes and infl ation settings. The ‘design-for-all’ solution off ered a 28% reduction in rolling resistance, an enhanced cornering performance, a matching grip and a satisfactory cushioning. (AUTH)

ABSTRACT: Tyres operated at or close to their friction limits show a highly nonlinear motion to force response. This state is called limit handling. The objective of this research is to minimize lateral path tracking error while the tyres operate in limit handling.

A HEURISTIC INVESTIGATION INTO THE DESIGN OF A DYNAMIC YAW CONTROLLER FOR A HIGH-SPEED TRACKED VEHICLE

David J Purdy


ABSTRACT: This work presents a heuristic investigation into the design of a dynamic yaw controller for a high-speed tracked vehicle to prevent it from oversteering. To the author’s knowledge, this is the fi rst time this problem has been examined. Accidents involving tracked vehicles generally result in signifi cant damage, serious injury and, in some cases, loss of life; this is due to their size and mass. A system that makes these vehicles operate safely in diffi cult and stressful situations would be welcomed. A switched mode structure is proposed for the dynamic yaw controller based on switching lines in the β phase plane. The lines are selected from the response of the vehicle at a speed, just before it goes into oversteer. The dynamic yaw controller is shown to prevent the vehicle from oversteering when it initiates a turn at its maximum speed on an off -road sandy track, with a coeffi cient of friction between the tracks and ground of 0.68. At a reduced coeffi cient of 0.5, the dynamic yaw controller applies the brakes continuously, which brings the vehicle to a stop; whether this is good or not depends on the situation. (AUTH)

A NEW METHODOLOGY TO STUDY THE PANTOGRAPH–CATENARY DYNAMICS IN CURVED RAILWAY TRACKS

Pedro Antunes et al


ABSTRACT: The pantograph–catenary system is responsible to provide an uninterrupted energy supply to power electric traction railway vehicles. The analysis of the dynamic behaviour of the catenary and pantograph, as well as its interaction, has been the objective of active research to improve energy collection quality. This work proposes an approach for the fully three-dimensional dynamic analysis of pantograph–catenary interaction in general railway tracks including curves. The catenary model and the trajectory of the pantograph base are defi ned with respect to the track geometry considering the conventional defi nition used by the rail industry, i.e. the track curvature, cross-level and vertical position. The pantograph is modelled using a multibody formulation being its base motion constrained to follow the generalised trajectory from the railway vehicle roof. The fi nite element method is used to model the catenary. A co-simulation procedure is set to establish the coupled dynamics of the two systems. In order to demonstrate the methodology, setup models for curved catenaries, analyse modelling implications and highlight applicability, realistic case studies of pantograph–catenary interaction in high-speed rail operations are presented and discussed. In the process, signifi cant diff erences are found in the dynamic response of the catenary in curved and straight tracks. (AUTH)

KEY PARAMETER SELECTION OF SUSPENDED MONORAIL SYSTEM BASED ON VEHICLE–BRIDGE DYNAMICAL INTERACTION ANALYSIS

Qinglie He et al


ABSTRACT: This study aims to select the proper key parameter values of suspended monorail system (SMS) by analysing the vehicle–bridge dynamical interaction. First, a coupled dynamical model of vehicle–bridge system is established by using ANSYS parameter design language (APDL). Further, the car-body accelerations obtained by the proposed model and fi eld test are systematically analysed in frequency domain. A sensitive parameter infl uencing the vehicle ride comfort is identifi ed. The key parameter value of the bridge is selected with the objective to improve the vehicle-bridge vibration level. Finally, accounting the out-of-round tyre, the dynamical performance of vehicle and bridge is investigated under periodic harmonic disturbance, and proper values of secondary suspension parameters of vehicle subsystem are selected. Results show that the space between bridge stiff eners is a sensitive parameter that can aggravate the car-body acceleration. This space is fi nally suggested to be 1.2–1.4 m in order to eff ectively reduce the vehicle-bridge dynamical interaction. Controlling the vertical stiff ness of secondary suspension to be less than 0.2 MN/m, the periodic harmonic disturbance can be eff ectively isolated. To ensure a reasonable vibration level of vehicle–bridge system suff ering from periodic harmonic disturbance, the vertical damping of secondary suspension is suggested to be about 27 kN s/m. (AUTH)

SMALL OVERLAP ASSESSMENT FOR EARLY DESIGN PHASES BASED ON VEHICLE KINEMATICS

Iván Cuevas Salazar et al


ABSTRACT: Assessing the eff ectiveness of a vehicle structure concerning the minimisation of intrusions during the early phase of crashworthiness design is challenging because of the lack of a detailed layout of the structural components. In the case of the IIHS Small Overlap Frontal (SOF) crash test, the vehicle kinematics, specifi cally, the instantaneous positions of the occupant compartment relative to the barrier, are available even early in the development. Hence it is proposed here to use these vehicle kinematics as a predictor of the resulting structural intrusions at the occupant compartment. For this, a method is presented to distinguish between two kinematic responses, glance-off and deformation mode, and identifi ed them by an automated video analysis. This is validated by an example using 182 vehicles subjected to the SOF crash test. This categorical defi nition is used along with the inbuilt kinematic parameters to derive a linear model for the prediction of the intrusions at the Upper and Lower Hinge Pillar, Upper Dash and Left Instrument Panel providing a fi rst estimate of the vehicle structural rating and thus, overcoming the lack of knowledge uncertainties inherent to this design phase.

CHASSIS SYSTEMS GAINING TECHNOLOGICAL ADVANCEMENTS; PLAYING ACTIVELY IN SAFETY

side, the market growth of this segment is restricted by the cost of these systems, with suppliers coming under high pressure to maintain costs, while maintaining the quality of these materials to meet stringent quality control, the report noted.

RECENT INNOVATIONS: The chassis in its primitive form was a metal frame that consisted of cross bars that enabled the placement of the vehicle body along with other components such as the engine, transmission, axle, wheels and bumpers. However, the role of the chassis has transformed over time, especially with regards to safety systems and related electronics. From being an unconnected, separate component on a vehicle, the chassis now plays a signifi cant role in enabling advanced driver assistance systems (ADAS) that eventually lead to autonomous driving vehicles. Adaptive chassis technologies are a major part of active safety systems in ensuring balance between safety and comfort, while operating a vehicle.

Modular systems that pack together multiple components into a package are a growing trend in the automotive industry. Such modules enable vehicles to become compact in terms of overall size, while also making them more effi cient with regards to performance. This phenomenon has also been implemented around chassis systems, where complementing components of suspension, braking and drivetrain are clubbed into a single package to bring about expected benefi ts. Another form of modular chassis systems is where a single chassis can be modifi ed to accommodate the development of diff erent types of vehicle body styles in a few steps. A major advantage of such modular chassis designs is that they enable design alterations easily and reduce the time to market for new models.

A good example of advanced electronic systems-based chassis system is that of Integral Chassis Control (ICC) that has been developed by ZF. The ICC technology connects individual chassis systems to enable enhanced driving dynamics and achieves the goal of improving the driving experience to become more experiential, engaging and

Any vehicle, be it two, three or four-wheelers, or for that matter even an off -highway vehicle or farm equipment all require certain basic components to function. The driveline is what makes a vehicle move and stop, the bodywork, exteriors, interiors, electronics and safety systems provide functionalities of their own. However, all these parts and components need to be placed on a frame or require to be held together strongly, for which the chassis is the base. There may be multiple types of chassis, such as ladder-on-frame, monocoque, space or hybrid, but they all perform the same role of providing the platform for all other components of a vehicle to be assembled on.

According to a report released by Inkwood Research, the automotive chassis systems market is expected to register CAGR of 4.60 % over the 2019-2027 period and is expected to reach a revenue of $ 114.575 bn by 2027. The research fi rm said the global automotive chassis systems market is driven by advancements in technology, growth in demand for low-emission automobiles, increasing demand for vehicles and fi nancial fl exibility for automobile purchase. The report also revealed that control arms are the majorly-used components of the automotive chassis system, with active kinematics control emerging as the fastest-growing chassis system.

The growth in demand for low-emission automobiles is considered the primary driver for the growth of the global automotive chassis systems market, since emissions and fuel consumption of a vehicle are directly proportional to the vehicle weight, noted Inkwood Research. The production of vehicles with lightweight chassis systems is expected to reduce vehicle weight, which has prompted various automotive design and engineering companies to line up plans to manufacture lighter and sturdy chassis. On the fl ip

that manufacturers look to in case of extreme requirements.

INTO THE FUTURE: There is a growing demand for high performing chassis, wherein the mechanical features of the chassis are still intact, along with the addition of mechatronic systems. These electromechanical systems enable features like road stabilisation, braking and vehicle stability control. There is also a trend where the power source of these electromechanical systems on the chassis is provided by an electric motor, rather than the existing engine in the vehicle. This perspective is in line with making future chassis systems environmentally-friendly, while also making them connected and intelligent. These features also enable the chassis of the future to become easily adaptable with safety systems required for autonomous driving.

The increased level of electronics into chassis systems also enables them to off er customised functions that can be used to off er convenience for vehicle occupants. From lowering a bus to allow passengers to enter and exit, to increasing a car’s ground clearance to pass through a rough patch, and enhancing traction in a motorcycle, the mechatronic interventions in chassis systems play an important role in enabling a comfortable drive/ride combined with a high level of safety.

Therefore, the chassis is no longer an independent component of an automotive, rather a key part of the overall vehicle system that enhances multiple features. The areas that chassis systems cover include safety, convenience, driving dynamics and even cleaner mobility. Further, such trends of integrated systems in vehicles will be the direction of future mobility that will eventually look at being completely autonomous in nature.

DEVELOPING A SPARK-IGNITION ENGINE WITH 45% EFFICIENCY

In this case, it is possible to operate the engine in a very limited engine map range. The core of IAV’s concept approach presented in this paper is a signifi cant increase in compression ratio combined with charge dilution and an active pre-chamber ignition.

MOTIVATION: The ambitious target set by the EU Commission to reduce CO2 emissions signifi cantly increases the requirements for future powertrain concepts. The 37.5 % reduction based on the already stipulated value of 95 g CO2/km from 2021 demands clear steps to reduce fuel consumption, particularly in spark-ignition engines. This

safe by connecting electronically-controlled components such as steering, suspension and braking systems.

Another technology worth mentioning is the Electromechanical Roll Control system, which uses a 48 V electric motor that is installed on the axle to off set vehicle roll motion in a short period of time. This system results in reduced body roll that can enhance cornering capabilities and improve ride quality on bad roads. Similarly, other electro-hydraulic levelling technologies use actuators to alter ride height, and make it easier for low-slung vehicles to overcome obstacles on the road.

MATERIALS OF CHOICE: Since the chassis is equated to the backbone of a human being, the importance of its strength and performance cannot be implied enough. This has always required the chassis to be one of the most robust components in any type of vehicle body. It should also be noted that the chassis is one of the most voluminous part of a vehicle, naturally meaning that it carries a lot of weight. There has been transition in the material used to make vehicle chassis over time, and this research continues to be carried out continuously.

In earlier times, the chassis of a vehicle was made of iron, due to the ideal characteristics of being strong and robust. However, the reaction of iron to collisions and impacts was not safe for vehicle occupants of four-wheelers, which then made the industry move towards high-strength steel for chassis manufacturing. This material off ers improved crash worthiness, while increasing the level of safety of occupants. Even in two-wheelers, the use of steel in manufacturing chassis has been the norm as a result of the benefi ts off ered by the metal in terms of strength, durability as well as cost.

Moving ahead, the material of choice for chassis and body structure construction on a wider scale has been aluminium. The use of aluminium results in decreasing the weight of the vehicle, and this feature combined with the metal’s high specifi c energy absorption and precise strength make it optimum for usage in various vehicle chassis systems. Another additional feature of aluminium is that it is corrosion-resistant, which also makes it a material of choice for the automotive industry. On the down side, the repair of aluminium is a tedious process, with certain repair processes not being able to be carried out at all. This is the limitation that aluminium has, but even then it is increasingly being adopted for construction of chassis and body structures, which can result in up to 20-30 % reduction in the total vehicle weight.

A material that has been in use for construction of various components to increase the strength exponentially, while reducing weight is carbon fi bre. However, this material has been limited to sports vehicles, and has trickled into the top-most segment of luxury vehicles. The extremely high cost of carbon fi bre manufacturing can be attributed as the reason for its limited usage as a material for constructing components such as chassis. However, it is also a material


will require powertrain concepts with low CO2 emissions in all driving scenarios. Combining internal combustion engines with electric drive components produces additional challenges on the one hand, but on the other hand, it also creates opportunities for making combustion engines essentially more eff ective through targeted optimisation in the clearly restricted map range. Higher effi ciency on the motorway and in customer-relevant driving cycles allows not only to avoid the drawbacks from increased vehicle mass with discharged battery but also considerably reduces fuel consumption.

ARCHITECTURES OF HYBRID POWERTRAINS:Hybrid powertrains are classifi ed either in terms of the installed electrical output (micro, mild or full hybrid) or according to the layout of the electric motor (in series, in parallel or power split). Giving due consideration to technical complexity, consumption potential, performance and costs, the parallel hybrid off ers an advantageous topology.

Full hybrid architecture is necessary to achieve the lowest CO2 emissions. It permits implementation of extensive hybrid functions such as recuperation and boosting, besides all-electric driving right through to cross-country speeds. The addition of plug-in capability and the use of renewable energy further increase the savings potential. (1) shows the approach taken in the concept using the combustion engine in the highly restricted map range as part of the hybrid powertrain [1]. The concept resolves the trade-off between low-end torque (LET), rated power and part load. Areas at low part load are operated in all-electric mode. When the battery is not fully charged, this area is bypassed by shifting the operating point, thus eliminating the need for dethrottling at part load. Electric boosting also reduces the signifi cance of LET engine speeds with positive impacts on knock and pre-ignition tendencies. As a result, suitable technologies can be optimised with a focus on maximising engine effi ciency.

TECHNOSCAN

THERMODYNAMIC CONCEPT: The key aspect of the concept consists in augmenting thermal effi ciency by clearly increasing the compression ratio. This is achieved by restricting the LET range. Knock reduction is also necessary and is achieved by using cooled Exhaust Gas Recirculation (EGR) with high EGR rates as well as Miller valve timing, combined with relatively short combustion durations for lowest combustion losses. The latter must be safeguarded with an adequate ignition system, which is always needed for igniting highly diluted mixtures.

Lower caloric losses are another important eff ect of charge dilution. High wall heat losses caused by maximum compression ratio and optimum centre of heat release must be counteracted by an augmented stroke-to-bore ratio as well as charge dilution. Minimising gas exchange losses necessitates a suitable exhaust gas turbocharger optimisation with a large turbine for lowest exhaust back-pressure, which can only be implemented by reducing the stress at the LET of a hybrid powertrain. The concept is rounded-off by an additional improvement in gas exchange with a port design optimised for high fl ow rates and a compressor wheel rated to the best point.

DESIGN FOR 45 % EFFICIENCY: A complete redesign of the combustion engine entails optimising a large number of parameters. The partly diametric behaviour of individual loss mechanisms creates a multi-criteria optimisation challenge. To this end, a 1D gas exchange simulation is coupled with an IAV proprietary mathematical optimiser. The engine model used for this purpose incorporates validated sub-models for knock sensitivity, supercharging, wall heat and combustion.

The optimisation leads to a large number of individual hardware settings with discrete characteristic fi gures for engine speed, load, compression ratio and the resulting engine effi ciency, (2). The optimum confi guration produces an effi ciency level of 45.4 % at 4,400 rpm. With optimisation focussing on the cycle-relevant operating range, effi ciency of up to 45 % can be achieved at a speed of 3,000 rpm,

The effi ciency of combustion engines can be signifi cantly improved, when used as part of a hybrid powertrain

as explained below. These settings provide a compression ratio of 17.4, an EGR rate of 42 % and a stroke to bore ratio of 1.25.

(3) shows the thermodynamic eff ects of the 45 % setting. The base engine – a turbocharged 1.4 l gasoline engine with direct injection – with a compression ratio of 9.6 at the operating point 3,000 rpm and 12.6 bar serves as a reference. Boosting just the compression ratio only results in a slight increase in engine effi ciency, (3) (middle). Even ignoring knock combustion, the increase is no more than 2.4 percentage points due to higher wall heat losses. The actual increase in knock tendency results in far later centres of heat release and an even higher increase in the sum of wall heat and combustion losses.

Finally, all hardware components have to be optimised to achieve the 8.5 % increase in thermal effi ciency from the augmented compression ratio, (3) (right). Here, the focus is on using a very high EGR rate of 42 %. EGR reduces peak temperature due to higher thermal capacity, while at the same time there is a larger gas mass in the cylinder, with signifi cant reductions in the elevated wall heat losses. A stroke-to-bore ratio of 1.25 brings about further reductions in wall heat. Effi ciency is further enhanced by reducing caloric losses and decreasing knock tendency by means of a cooled EGR with an ideal centre of heat release.

Minimising combustion losses necessitates short combustion durations of 20 °CA (10 to 90 % fuel conversion) despite high charge dilution. A suitable ignition and injection system is necessary for ignition of highly charge-diluted mixtures with fast conversion at the same time. The gas exchange is optimised by means of an enlarged turbine and a compressor design optimised to the best point. This leads

to constant gas exchange losses despite a higher fl ow rate and charge pressure.

PRE-CHAMBER IGNITION FOR CHARGE-DILUTED MIXTURES: In addition to known charge dilution with air (lean combustion), effi ciency can also be improved by dilution with exhaust gas. There are advantages in preserving the stoichiometric fuel to air ratio with exhaust aftertreatment by means of three-way catalytic converters. But the EGR rate is limited by the potential of the ignition system. IAV has developed an active pre-chamber ignition system to resolve the trade-off between high EGR rate and ignition capability. A smaller gas mass is encapsulated to make it easier to shift the composition of the partial charge into the ignitable range. At the same time, the pre-chamber generates high-energy fl ares to facilitate the ignition and swift burn-through of highly charge-diluted mixtures. A special injector is needed to achieve ignitable mixtures with high EGR rates to fl ush the pre-chamber with fuel/air mixture. The EGR rate at the ignition point is thus clearly reduced compared to the main combustion chamber. The test bench measurements shown in (4) illustrate the signifi cant increase in residual gas compatibility of the combustion process.

The desired signifi cant increase in effi ciency is generated by the favourable centre of heat release in the range of limited knock as well as the shorter combustion durations [2, 3]. However, the lack of an adequate purge gradient at the test bench (no active purging pump) meant that the EGR rate was limited to 32 % without restricting combustion stability.

(4) Comparison of pre-chamber ignition with conventional spark

plug at high EGR rates (© IAV)


SYSTEM STRUCTURE & POTENTIAL: (5) shows how the active pre-chamber is incorporated in the overall engine concept. The single-stage supercharged spark-ignition engine with exhaust turbocharger, direct injection and charge-air cooling makes use of exhaust gas aftertreatment rated for stoichiometric operation. Additional hardware components are needed to implement the ascertained characteristic fi gures and settings. The pre-chamber ignition system is the central element. The diagram shows a conventional spark plug in the pre-chamber volume as well as the necessary fuel/air injector. The latter needs an additional low-pressure fuel system together with air supplied by an electric pump in combination with a pneumatic pressure reservoir. There must be an adequate purge gradient between the exhaust and intake system to achieve EGR rates above 40 %.

The low-pressure circuit with post-turbine withdrawal and gas injection downstream from the compressor off ers several advantages. Regardless of the operating point, there is a natural pressure gradient that just needs minimum boosting from the purge pump [4]. Furthermore, exhaust enthalpy can be fully exploited for supercharging, and the reduced withdrawal temperature clearly reduces the power demand of the EGR cooler. EGR withdrawal downstream of the three-way catalytic converter and particulate fi lter reduces soiling in the intake system [5].

ignition with stoichiometric operation across the entire map. Achieving this clear improvement depends on the possible restriction of the engine map range in the hybrid setting. An actively purged pre-chamber spark plug permits ignition of highly diluted mixtures with EGR rates of up to 42 %. The high EGR rate in combination with long-stroke layout limits wall heat losses with clearly increased compression ratio. The strongly reduced LET and EGR cooling still permit adequately high mean pressures in the full load range. The targeted layout of the turbocharger combined with a low Miller degree prevents higher gas exchange losses. It is thus possible to achieve effi ciencies up to 45 % at the best point of the map. Given the close proximity of the combustion engine best point and the operating points for typical long-distance applications, this concept promises a considerable CO2 reduction in customer consumption for cross-country or motorway driving. Furthermore, extending high effi ciencies well into the part load range is also benefi cial, in terms of the certifi cation cycle.

Although the existing variabilities in the valve train are not needed for point layout, they can extend the high effi ciency level to other map areas. (6) shows the effi ciency map ascertained with the selected setting. Besides the 45 % point, the range of effi ciencies above 40 % can be extended well into the WLTC-relevant part load range. The fuel-saving potential thus achieved with pure combustion engine operation of 0.6 l/100 km in WLTC or 1 l/100 km at 130 km/h for a C-segment hybrid vehicle is perceptible in terms of fuel consumption in customer operation, regardless of whether the hybrid functions of the powertrain can be used in view of the battery charge status.

the newer modular and fl exible manufacturing way of life for long term sustainability. These could be avenues to evaluate; for existing manufacturers to dabble in both these segments, while trying to leverage any form of synergy for economies of scale and/or chose to use their strengths in either segment of choice.

In other forms of mobility catering to urban, captive and low speed target customers, the additional cost of hardware and technology due to novelty is higher today and adapting a specially designed de-scaled chassis that fi ts such applications can off set the cost burden to consumers. It is also an advantage techno-socially to chassis and vehicle manufacturers, in terms of providing employment and fl exibility to consumers, and the environment.

For the mature conventional mobility operating in a diff erent ecosystem, the systems have been steady over decades, the costs have stabilised and lower compared to the new-age powertrains. Transversely inter-deploying chassis models to meet both the system design specifi cations will provide persuasive solutions. Of course, with an emphasis on low carbon footprint and better fuel effi ciency, these sub-systems have naturally evolved to become lighter, structurally robust for safety & crash norms, embedded integrated controls with increased electronics and software that provide good fl exibility and ride comfort.

Innovations have enhanced driving comfort through lower steering eff ort resulting in reduced driver fatigue, improved driving confi dence due to better steering response and better manoeuvrability of vehicles that reduces turning radius. Better energy management of chassis sub-systems has contributed to better fuel effi ciency. Adaptability of the chassis systems with body-in-white options has opened-up styling avenues, fl exibility in use of powertrains, game changing manufacturability, overall carbon footprint reduction and better fuel effi ciency of the vehicle.

GAME CHANGERS: Steering and suspension systems in the chassis can be designed and adapted similarly for both facets of application, again, as they are primary conduits of transferring road instabilities and loads to vehicle occupants. Over the years, there have been active sensing systems that magnetically or electronically control damping and have the capability to change ride-comfort real-time in an on-road or off -road use environment.

The measure of driving experience, ride comfort and safety, can be enhanced through prudent real-time adaptive chassis sub-systems that have plug and play modules suited for target markets, vehicle segments and terrains. These could be the game changing techniques for long term sustainability.

The new normal of mobility will challenge the principles of chassis systems, with autonomous driving, shared mobility, and e-mobility co-existing along with conventional mobility platforms. With changing urbanisation trends, many moving to suburbs and preferring to work from home, lifestyles changing to driving shorter distances at lower speeds, experts are asking if it is necessary to revisit the assumptions of designing personal mobility chassis systems for two facets of applications – the fi rst set being for non-highway low speed mobility segments, short distances & city centres, and the other set for the high speed, highway and long-distance driving consumers. This could result in distinctly dividing the manufacturing and OEM segments to work with diff erent sets of assumptions.

Recently, there has also been a new development that has seen very diff erent manufacturing companies from non-core mobility segments. These manufacturers may possibly conquer the new-age technology vehicle segments along with allied verticals and relevant chassis manufacturing due to the new-age bandwidths. The conventional mass markets could continue with the existing experienced OEMs that are experts in cost competitiveness.

ADAPTIVE CHASSIS SYSTEMS: With safety and effi cient energy management being non-negotiable, the progressive model could have scalable real-time adaptive chassis systems that have plug-in modules suited for target markets and terrains that can be up-scaled or de-scaled depending on the application. Though it is intricate, this could become

ETAUTO OPINION: WHAT’S THE POWER OF ZERO IN AUTO?

Chanchal Pal Chauhan

ETAuto, Updated: May 05, 2020, 10:07 IST(Source: ET Auto .com)

New Delhi: Covid-19 is a great leveller.It makes all in the game ‘equal’.

FIAT India is at the same level as Maruti Suzuki India for the month of April. Across all parameters; Sales, Revenue, Profi ts, Market Share or the Dealers woes. The real tailender matches the top segment leader in all aspects.

As the Indian car market tanks to its lowest ever, the fringe carmaker meets the mightiest across the standards that have bridged them apart. Maruti sells more cars than all the other automakers put together. FIAT sold mere 125 cars in FY ‘20 to Maruti’s million in the same fi scal year. Oops, but not in this fi scal year. Their sales were the same as for all the others across the segment.

So, basically there’s no market leader for April, fi rst of many fi rsts hitting the industry. It is not just that ‘ZERO’ is the sum of all denominators. There are a host of changes on the anvil that would be hitting many players right from OEM’s to their dealers’ and ultimately the customers.

Indian automotive industry bore the full brunt of country-level lockdown measures where numerous automakers, perhaps all, returned with their worst monthly showing a ‘ZERO’ in decades.

Now the entire chain in the automobile industry would be overhauled to a new beginning. Not just how the players would take it forward, in terms of resurrecting the entire value chain, but also the standard operating procedures (SOP) needs to be rebooted for the new challenges.

“It’s a great learning to cut the fl ab. Basically, one of the major absorptions is ‘Zero Figure’ that is more agile, nimble and raring to go, while changing the dynamics of the market. April was a great opportunity to introspect and value our stakeholders, who stood united with us without any commercial returns or gains,” says Shashank Srivastava, Director for Marketing & Sales at Maruti Suzuki India that is all set to resume its production and offi cial functioning this week. So as the lockdown blues suggest that all the manufacturers irrespective of their size and scale would be starting from the same point. All would be rearing to set their house in a new order after a two-month hiatus with virtually everything dismantled. These all would be ratting to kick start production with almost exasperated suppliers along with starved and dilapidated dealers rearing to make a killing in an empty market.

While many core company functions would make a gradual shift to the digital world, it’s the auto industry that would enter into the era of a new world.

“It’s a new world out there. There aren’t any prejudices anymore in this industry. ‘ZERO’ is the new normal and all the 16-carmakers begin the new fi sal at the same note,” says a senior executive preferring anonymity.

While most automakers are awaiting guidelines to kickstart production in a new normal of sanitised atmosphere, it’s the new ‘low of morale’ they would now be dealing with. Most while outlining their strategy to reopen their plants would need not just a favourable manufacturing strategy, but a host of measures from logistics operations to dealer’s profi tability to avoid the ‘ZERO’ of April in the future.

“Notwithstanding the complete freeze on retail operations which lead to this ZERO sales, we utilised the period for an online onslaught. Our ‘Click-to-Buy’ contactless initiatives have gained massive traction with customers in April and paved the way to new retail formats in the personal mobility space,” says Hyundai Director for Marketing & Sales Tarun Garg.

Larger OEMs with a mammoth workforce and mega manufacturing plants would undergo bigger headaches. While smaller manufacturers’ would be nimbler to rise back faster. They would be better placed to restart in a regulated and controlled environment, where caution at every step to avoid contagion would be of extreme importance.

“The start will be slower. A larger plant would require more eff orts to manage the heavy quantum of workforce in a huge mechanical setup, where only a fraction of the capacity could be utilised. Even as two wheeler companies are fi nding it diffi cult to restart their plants, the problems for most carmakers would be more compounded with multiple suppliers and vendors to start from ‘ZERO,” said a senior production incharge of a major automaker.

Federation of Automobile Dealers’ Association or FADA president Ashish Kale says, that ‘It’s a new phenomena for the industry and hope never reoccurs’, while asking the government for support in the form of GST rate cut and interest subvention through banks and NBFCs to help customers in terms of reduction in the cost of ownership to possibly spur demand.

“This ‘ZERO’ is a great opportunity to scale new heights, leaving the long-standing slowdown and the lockdown blues behind us, and achieve the unthinkable by developing new retail models to serve customers, while adding a fool-proof contingency backup plans to face such eventualities in the future,” he quipped.

AUTO INDUSTRY EXPECTED TO REBOUND IN SECOND HALF OF FY21: EMKAY

Anirban Mitra

TIMESOFINDIA.COM, Updated: May 5, 2020, 20:41 IST(Source: The Times of India)

NEW DELHI: Near-term volume performance in the automobile industry is expected to remain under pressure, but is expected a rebound in the second half of the fi nancial year 2020-21, led by a low base, pentup, according to Emkay Global.

The manufacturing sector hit by the nationwide coronavirus lockdown forced auto fi rms to shut their production. Following the government’s guidelines, dealers are gradually re-commencing operations in green and orange zones. In red zones, most dealers expect to commence operations from May 18.

The auto sector has endured tough times over the past six quarters due to a cyclical downturn across segments, Emkay noted.

“Near-term volume performance is expected to remain under pressure, but we expect a rebound in H2FY21, led by a low base, pent-up demand and better rural sentiment. We retain our positive view on the Auto sector at current valuations. Although companies with global linkages are relatively more vulnerable, domesticfocused ones are relatively less impacted and likely to witness an early recovery,” quoted the report - ‘Automobiles; April 20 volume review’ - by Emkay global.

According to Vahan, the vehicle registrations were lower by over 70% yoy across segments, owing to the Covid-19 lockdown. April 20 registrations were meager, at around 21,000 units for passenger vehicles, 314,000 units for two-wheelers, 19,000 units for commercial vehicles, 5,000 units for tractors and 10,000 units for three-wheelers

Wholesales were much lower than registrations, as dealers have been focusing on clearing existing inventories, and OEM plants are yet to ramp-up operations. PVs, 2Ws, 3Ws and CV OEMs clocked zero volumes in the domestic market.

Govt extends validity of Motor Vehicle Act related documents till June 30

PTI, Last Updated: May 06, 2020, 02.15 PM IST(Source: The Economic Times)

New Delhi: Amid lockdown due to COVID-19 pandemic, the government has extended the validity of documents related to Motor Vehicle Act and Central Motor Vehicle Rules till

June 30. The validity has been extended for the documents whose validity expires between February 1, 2020 and June 30, 2020.

“Since it is not possible to renew documents during lockdown, various documents related to MV Act 1988 and CMV Rules 1989 whose validity expires between February 1, 2020-June 30, 2020 will be treated as valid,” Road Transport, Highways and MSME Minister Nitin Gadkari said.

WILL EXPEDITE SCRAPPAGE POLICY, EXTEND COMPLIANCE TIMELINES FOR AUTO COMPANIES WHERE POSSIBLE: GADKARI

By Nishtha Saluja,

ET Bureau, Last Updated: May 07, 2020, 03.22 PM IST(Source: The Economic Times)

Transport minister Nitin Gadkari on Thursday called for expediting the vehicle scrappage policy, which he said, will help reduce production costs for the automobile industry.

“I have been trying for the last two years to pursue the scrappage policy. I have asked the Secretary (ministry of road transport and highways) to expedite the scrappage policy. Because this will help reduce production cost,” Gadkari said in an interaction with SIAM Institute on Thursday.

“We will fi nd out what the obstacles are, and will clear it as soon as possible,” Gadkari added.

Gadkari added that the transport ministry was willing to extend compliance timelines on regulations under the motor vehicles act, barring those pertaining to road safety.

Automobile players present in the meeting asked for extension of timeline for registration of BS IV vehicles sold before March 31st, deferring compliance to fuel effi ciency norms, among other relaxations.

Talking of extending relief to the sector, Giridhar Aramane, Secretary, MoRTH said that the road sector will take a lead in extending relief measures to the industry, adding that a comprehensive package was in the works.

“The government of India, PMO and DEA are already working on a package which not only includes MSME, but all sectors of the economy,” Aramane said.

Gadkari also said that the auto industry, which has had a proven track record of registering “huge turnover, good exports,” should hedge for bad times as these.

“Is it possible for industry to reduce liabilities? Ups and downs occur in every fi eld, but somewhere we should have an arrangement for bad days, so it is very important to plan in advance,” Gadkari said.

AUTO COMPONENT INDUSTRY LIKELY TO WITNESS DOUBLE-DIGIT DEGROWTH IN FY21: INDIA RATINGS

PTI, Last Updated: May 12, 2020, 08.55 PM IST(Source: Theb Economic Times)

MUMBAI: Auto component industry is likely to witness a second consecutive year of a double-digit degrowth this fi scal mainly on account of disruption in operations due to coronavirus pandemic and the subsequent lockdown, according to a report.

The counter measures are likely to lead to lower income levels, weaker consumer sentiments, production disruptions, decreased industrial output as well as lesser movement of vehicles, resulting in a decline in global automobile demand and therefore, lower revenue and profi tability for auto ancillaries in FY21, India Ratings (Ind-Ra) said in the report on Tuesday.

“Ind-Ra expects that the auto ancillaries industry on an average could record at least 100bp EBITDA margin decline in FY21 and the profi tability decline for export focused auto ancillaries could be steeper as exports earn higher margins. The lower commodity prices could aid the profi tability for the sector, though only to a limited extent, due to pass-through agreements with OEMs and OEMs’ higher bargaining power.

“Also, some benefi t may accrue to companies with overseas manufacturing units, as certain economies have announced support measures to meet part of the fi xed costs during the shutdown period. A depreciated rupee rate could partly off set the decline in sales volumes; however, the benefi t is not expected to be signifi cant,” it said. However, the revenue and profi tability of auto ancillaries focused on domestic markets are likely to fare better due to higher content per vehicle on the back of evolving regulatory norms including BS-VI applicable from April 1, 2020, as per the report.

Entities with a large reliance on overseas markets are expected to face a higher demand risk as the key markets of the US and Europe have been the most impacted by the virus, which could lead to uncertain business conditions, it said. The US, Germany and the UK are the largest export markets for auto components globally.

Besides, India also exports around 12 per cent of the total auto components to economies with reliance on crude oil such as Africa and Latin America.

As much as 27 per cent of the total auto component production in the country is exported to various countries with the US accounting for 25 per cent of the total shipments form India, while Germany’s share stands at 7 per cent. The exports to the UK and Italy stand around 4 per cent, each.

Noting that over the past few years, India has emerged as the sourcing hub for many original equipment manufacturers (OEMs) globally due to its cost eff ectiveness in production and favourable geographical positioning to key markets such as Europe and Middle East, the India Ratings said the growth of exported components outpaced the overall growth of Indian auto components industry in FY18 and FY19.

“In the fi rst half of the previous fi scal (FY20), while the domestic auto components sector recorded a revenue decline of about 10.1 per cent over the year-ago period, exports recorded modest growth of 2.7 per cent y-o-y (in USD terms),” it said. The domestic components suppliers have also been expanding their exports exposure to diversify their revenue streams and limit dependence on the domestic market, while improving profi tability as exports are typically higher margin orders, according to India Ratings.

Furthermore, OEMs could postpone new model launches and investment plans, which would defer order off take, it said.

ACMA WELCOMES RS 20 LAKH CRORE ECONOMIC PACKAGE ANNOUNCED BY PM MODI

PTI, Last Updated: May 12, 2020, 10.28 PM IST (Source: Theb Economic Times)

NEW DELHI: Auto components manufacturers’ body ACMA on Tuesday welcomed the Rs 20 lakh crore economic package announced by Prime Minister Narendra Modi to overcome the impact of coronavirus pandemic, saying it will bring relief to many stressed sectors. The announcement of the economic package is indeed very welcome and is the need of the hour, Automotive Component Manufacturers Association of India (ACMA) President Deepak Jain said in a statement.

“This will bring much needed relief to several stressed sectors and industries, especially the MSMEs,” he added.

Stating that a signifi cant proportion of the industries in the auto components sector are MSMEs, Jain said, “ACMA is committed to making the Hon’ble Prime Minister’s vision of self reliance through localisation, global competitiveness, vibrant local manufacturing and a robust local supply chain a reality.”

Reforms in land, labour, liquidity and laws are critical to make India a driver of global economy, Jain said.

In his address to the nation, prime minister said the special economic package will amount to Rs 20 lakh crore, which is nearly 10 per cent of GDP.

It is for “labourers, farmers, honest tax payers, MSMEs and cottage industry,” he said.
