摘　　要：从机械动力学仿真的角度 ,研究 4WS汽车的瞬态和稳态操纵动力学特性。运用虚拟样机技术 ,给出4WS车辆在适当前轮转角及不同的大小、比值、方向以及转向时间差等后轮转角的条件下 ,车辆的瞬态和稳态动力学性能的表现。In this paper,mechanism dynamics simulation technology has been used to analyze the characteristics of transient and steady dynamic responses of 4WS vehicle. A multi-body dynamic model for a 4WS vehicle is set up using ADAMS software base on virtual prototyping technology and a simulation is carried out at different rotation angles, rotation directions of front and rear wheels as well as different time differences of rotation between front and rear wheels. The results are analyzed and some conclusions on the transient and steady maneuverability of the vehicle are drawn.
