摘　　要：建立了基于虚拟样机软件ADAMS/CAR的刚柔耦合动力学车辆模型,并通过动力学仿真及试验对比得到验证;利用试验及仿真结果对该车的操纵稳定性进行了相关评价;最后分析了该车前悬架的偏频特性。A rigid -flexible coupling multi -body model for a car is built base on virtual prototyping soft- ware ADAMS/CAR, which is verified by the comparison between the results of dynamic simulation and test, which is then also used to evaluate the controllability and stability of the car. Finally the natural frequency characteristics of front suspension are analyzed.
