In this paper, the optimum setting for suspension hard points was determined from a half vehicle suspension system. These optimized values were obtained by considering the Kinematic and Compliance (K&C) effects of a verified PROTON WRM 44 P0-34 suspension model developed using MSC/ADAMS/CAR. For optimization process, multi body dynamic software, MSC/ADAMS/INSIGHT and Design of Experiment (DoE) method was employed. There were total of 60 hard points (factors) in x, y and z axis-direction for both front and rear suspension while toe, camber and caster change were selected as the objective function (responses) to be minimized. The values of 5 mm, 10 mm and 15 mm were used as relative values of factor setting to determine the factor range during optimization process. The hard point axis-direction that has the most effects on the responses was identified using the Pareto chart to optimize while the rests were eliminated. As expected result, a new set of suspension system model with a selected of Kinematic and Compliance (K&C) data set were obtained, and compared with the verified simulation data when subjected to the vertical parallel movement simulation test to determine the best setting and optimum suspension hard points configuration.

The Impact

This article concerns a hybrid vehicle suspension system that can regenerate energy from vibrations. To further improve the performance of the hybrid vehicle suspension system, the design of the energy-regenerative circuit is investigated. First, the force tests of the linear motor used in the hybrid vehicle suspension were carried out, and the key parameters of the linear motor were obtained. Then, the selection procedures of the protective resistance, inductance, and initial terminal voltage of the super capacitor were discussed. These aforementioned parameters’ values were determined by considering the impact of the hybrid suspension on the dynamic performance indexes and the energy-regenerative efficiency. Simulations showed that, in comparison to the original hybrid suspension system, the designed hybrid suspension effectively improved the energy-regenerative efficiency, and that the dynamic performance indexes of the suspension were synchronously improved. Given the result of the simulation analysis, which were validated by bench tests, it is shown that the optimized energy-regenerative circuit presents an enhanced regeneration efficiency, with an improvement of nearly 13% compared to the original suspension system.

Vehicle Suspension System

Vehicle suspension system with hysteretic nonlinearity has obvious nonlinear characteristics, which directly cause the system to the possibility of existence of bifurcation and chaos. Two degrees of freedom for the 1/4 body suspension model is established and the behavior of the system under road multi-frequency excitations is analyzed. In the paper, it reveals the existence of chaos in the system with the Poincaré map, phase diagram, time history graph, and its chaotic behavior is controlled by nonlinear feedback. Numerical simulation shows the effectiveness and feasibility of the control method with improved ride comfort. The results may supply theoretical bases for the analysis and optimal design of the vehicle suspension system.

Vehicle suspension system plays an important role in the influence of whole vehicle handling and riding characteristic, as an important part of vehicle chassis system. In the paper, based on the basic test parameters and relevant modeling data of ex-MacPherson suspension of the sample car, the virtual prototype model of this suspension is built by making use of ADAMS/Car module. According to the requirements of the relevant design, some of the model parameters have been adjusted, on the basis of which, K&C characteristic simulation before and after the adjustment is done. The results show that, after adjustment, the majority of suspension K&C characteristic is satisfied, and improved the kinematics of the suspension system.

A novel design of a planar suspension system (PSS) is proposed to overcome the limitation of a conventional vehicle suspension system that cannot sufficiently absorb the vibrations and shocks caused by the road obstacles in the longitudinal direction because of the very stiff longitudinal connections between the chassis and the wheels. The rather stiff longitudinal linkages are replaced by a spring–damper strut. The results of the investigation into the transient handling behaviour of a vehicle with a PSS in three different scenarios are presented. These include a vehicle turning on a bumpy road, a vehicle turning combined with braking, and a lane change manoeuvre combined with acceleration. The results obtained from this study demonstrate that the PSS vehicle can effectively suppress the vibrations and shocks in the longitudinal direction without causing the handling performance to deteriorate. It has been shown that the vehicle-handling behaviour is generally comparable with, and under some conditions even better than, those reported for vehicles with a conventional suspension system.

The Cost

Major contributors to the road damage are Heavy Goods Vehicles (HGV), resulting in high maintenance costs of roads. This high cost makes it necessary to look into the issue seriously for minimizing the road damage. An Automobile Engineer can reduce road damage through the efficient design of a suspension system. The design involves satisfying the two conflicting criteria of riding comfort and vehicle handling with the restriction on the suspension travel. This paper involves designing an automobile suspension system, to improve the performance of the vehicle without a significant change in the cost of the suspension system and minimize road damage. To achieve the aforesaid objective, the use of a nonlinear passive suspension is suitable as compared to a linear passive suspension system. For the analysis, a HGV model of vehicle suspension has been considered. The suspension system considered for investigation comprises of a cubical nonlinear spring and a linear damper. Road damage has been represented by the fourth power of the tire dynamic load. A genetic algorithm has been used to optimize the half truck model to minimize road damage. The solution has been obtained using MATLAB and SIMULINK.

Active Vehicle Suspension System

Synthesis of control design is an essential part for vehicle suspension systems. This paper addresses the issue of robust reliable H∞ control for active vehicle suspension system with input delays and linear fractional uncertainties. By constructing an appropriate Lyapunov–Krasovskii functional, a set of sufficient conditions in terms of linear matrix inequalities (LMIs) are derived for ensuring the robust asymptotic stability of the active vehicle suspension system with a H∞ disturbance attenuation level γ. In particular, the uncertainty appears in the sprung mass, unsprung mass, damping and stiffness parameters are assumed in linear fractional transformation (LFT) formulations. More precisely, the designed controller is presented in terms of the solution of LMIs which can be easily checked by Matlab-LMI toolbox. Finally, a quarter-car suspension model is considered as an example to illustrate the effectiveness and applicability of the proposed control strategy.

The torque vibration derived from in-wheel-motor transmitted to body frame through suspension system without the absorption of mechanical transmission parts, then excited every body panel to shape the vehicle interior noise, which influenced the quality of the vehicle NVH. This paper aims to build an accurate suspension system simulation model to analyze the influence of suspension parts parameters to system vibration transmission property. Basis on a novel empirical model of rubber bushing, a multi-rigid suspension model and a multi-flexible suspension model had been established respectively. The vibration characteristics of two models were simulated, furthermore the swept-sine exciting vertical force signal on wheel contact point were input on the simulation models to find the difference between rigid and flexible model. The simulation results show that: the multi-flexible model can reflect the vibration characteristics of the suspension system more accurately in the high frequency range and so is it more applicable to the simulation analysis of vibration characteristics of in-wheel-motor electric vehicle suspension system.

Vehicle Suspension System

The main objective of the variable damper controlled vehicle suspension system is to reduce the discomfort identified by passengers which arises from road roughness and to increase the ride handling related with the rolling, pitching and heave movements. This imposes a very fast and accurate variable damper to meet as much control objectives, as possible. The method of the proposed damper is to reduce the vibrations on each corner of vehicle by providing control forces to suspension system while travelling on uneven road. Numerical simulations on a full vehicle suspension model are performed in the Matlab Simulink toolboxes to evaluate the effectiveness of the proposed approach. The obtained results show that the proposed system provides better results than the conventional suspension system.
