摘　　要：影响汽车操纵稳定性的因素有很多,其中对于车身扭转刚度对操纵稳定性的影响研究较少。为了进一步研究车身扭转刚度与车辆稳定性的关系,利用ADAMS/Car软件对整车进行仿真,分析了转向角阶跃工况及稳态回转工况,对比车身扭转刚度的不同对汽车操纵稳定性的影响,得出汽车车身扭转刚度越大,汽车行驶越稳定,汽车的操纵稳定性越好。There are many factors that can influence the stability-of vehicle handling. Among them, there are few studies to the influence of body stiflness on the handling stability. In order to further study the relationship between body torsional stiflness and vehicle stability, ADAMS/Car software was used to simulate the whole vehicle, this paper analyzed working conditions of step steering and constant radius cornering, compared the influence of different body torsional stiflness influence on handling stability, it is concluded that the greater the torsional stiflness of vehicle body is, the more stable the vehicle is, and the better the vehicle handling stability is.

关 键 词：操纵稳定性 车身扭转刚度 角阶跃 稳态回转
