摘　　要：利用拉格朗日方程,建立了四轮转向车辆的非线性三自由度动力学模型。利用ADAMS软件,在虚拟环境中,建立了四轮转向车辆的虚拟模型,进行了动力学仿真,给出了车辆在多种状态下的运动及其动力学特性,并通过车辆的客观评价方法,对研究结果进行了分析,得出了一些有益的结论,对车辆的设计和分析具有一定的指导作用。The Lagrange＇s equation is used and a nonlinear 3 freedom degrees dynamics model for four-wheel-steering vehicle is built. A 4WS vehicle virtual model is built in the ADAMS environment and the dynamic simulation and analysis are carded out. The results of the dynamic simulation at various conditions and the vehicle＇s dynamic characteristics are given. Through the analysis and evaluation, some useful suggestions are obtained which can be used to direct the future design.
