摘　　要：随着汽车动态仿真的发展,产生了不同复杂程度的动力学仿真模型。通过将汽车车身看作是一个刚体,忽略悬置的发动机和驾驶员以及座椅,建立了一个非线性七自由度的立体模型,在正弦路面激励下运用Matlab/simulink软件对汽车整车系统进行仿真计算。仿真结果表明,该模型可能存在混沌现象。With the development of the automotive dynamic simulation ,different automotive dynamic models in the complex level have produced. The paper sees the vehicle body as a rigid body, ignores the overhung driver, engine and seats, establishes a nonlinear seven degree-of-freedom model, and uses Matlab/simulink software to make simulation calculation of the full-vehicle model which is stimulated by sinusoid forcing caused by road surface. Simulation results show that the model may exist chaotic phenomena.
