Dynamic Analysis and Suspension Optimization for New Energy Vehicle Based FE Model

Abstract:

In this paper, the random vibration theory is employed to research on the dynamic performance of suspension system of new energy vehicle. Based an efficient sensitivity analysis method, vehicle ride comfort and maneuverability have been investigated by suspension parameters optimization. The pseudo-excitation method has been used to analysis the dynamic responses and sensitivity, the computation performance and adaptability have been investigated by using numerical examples. Hence a convenient and accurate computation method for new energy vehicle optimization design is demonstrated and some useful conclusions are drawn.
