摘　　要：利用机械系统动力学软件ADAMS/Car建立了整车虚拟样机模型,其中转向系统考虑了静摩擦环节,动力学系统嵌入了面向结构的差速器模型,在结构上保证了左右车轮的相互协调。对整车模型进行典型工况仿真分析,结果表明引入静摩擦后,汽车能够抵抗驾驶员的微小转向干扰输入;受到路面不平干扰和左右车轮有转速差异时,驾驶员操纵方向盘自由和固定状态的曲线比较说明,两侧车轮的耦合能减小侧向偏移距离,整车仍然具备良好的线路保持性,使车辆具备了良好稳定性。A virtual prototype model of vehicle was built by the use of mechanical system dynamics software ADAMS/Car,in which the static friction is considered in the steering system and the differential model for the structure is embedded in dynamical system,which ensured co-ordination between the left and right wheels in structure.Then the model of the vehicle is analyzed by simulating its typical operating conditions.The results show that car can resist driver tiny steering disturbance input with static fiction;When the pavement is not smooth and the rotate speed between left and right wheels differs,the comparison curves of free and fixed state of the steering wheels controlled by car driver show that wheels coupling can reduce the lateral offset distance,the car is better in line keeping performance and stability.
