Abstract
Virtual proving ground (VPG) technology is applied to simulate vehicle ride comfort. The multi-body dynamics model for vehicle virtual simulation and random road surface are established under VPG. The body acceleration time-domain curves and frequency-domain power spectrums are obtained by LS-DYNA. Total weighted acceleration of vehicle ride comfort is evaluated by root-mean-square method. The effects of suspension system on the vehicle ride comfort are analyzed by changing stiffness and damper parameters of suspension. Simulation results show that simulation of vehicle ride comfort based on VPG can truly reflect real test condition , and results achieved are accurate and reliable.
