Research and Optimization of Vehicle Handling Stability Based on Multi - body Dynamics

Abstract

Abstract Based on multi-body dynamics virtual simulation method, the vehicle simulation model is built and the transient response characteristics of the vehicle are analysed under the steering angle step input. According to the results, the improving method is given. The optimization and stiffness test of tuning bushing are carried out, and the better bushing stiffness is obtained. The vehicle steering transient response performance improvement effect is obvious. This method provides theoretical reference for structural engineers.
