Abstract: To realize the virtual development of the automobile products, a multibody system dynamics simulation model was built for a certain domestic passenger car by means of a redeveloped module of ADAMS/CAR. According to the national standard and the test evaluation method on the vehicle steering stability, the simulation tests under typical working conditions such as steady steering and steering returntostraight ability test were performed and discussed. Comparison between the simulation and the real car tests shows that maximum difference of the main parameters was less than 10%. For the performance indexes which were imperfect both in the real car test and in the virtual car simulation, ideal simulation results could be obtained after adjustment of the parameters.
