Dynamics Simulation and Optimization of Ride Comfort for Car on Random Road



Lin Hu and Jing Huang
 
ABSTRACT

To ensure the safety, high efficiency and comfort of traffic and transportation, the research of automotive ride comfort is getting more and more important. Vehicle ride comfort is one of the most important performances of vehicle. At first, the subsystems dynamics analysis models were separately established, such as front suspension, rear suspension, person-chair system, steer system, tire and transmission subsystems in this paper, then these subsystems assembled an vehicle dynamics analysis model with the car body and frame by used the software-ADAMS. Where after validated the correctness of the model by the experiment results of sample vehicle. Secondly, the vehicle ride comfort on random road was analyzed by the weighting acceleration root-mean-square value. Finally, the paper had studied influence of the spring stiffness, the shock absorber damping and the tire stiffness on vehicle ride comfort, based on simulation and analysis, The study proposed the optimization plan.
