摘要
分别采用二自由度汽车模型和四自由度汽车模型，对匀速直行ＡＵ－ｄｉ１００轿车在方向盘固定条件下的侧风响应进行了仿真，并得到了实车侧风稳定性实验的验证。利用上述模型，以侧风作用２ｓ后汽车的侧向位移为评价指标，分析了ＡＵｄｉ１００轿车结构参数对其侧风稳定性的影响，得出的结论可以推广到其它具有类似结构的轿车上。
This paper presents simulation methods for high speed automobiles passing through cross-wind under fixed control, using two-degree-of-freedom(DOF) model andfour-degree-of-freedom model, which give good coincidence with the experimental results. Based on these models, the effect of the parameters' is analysed on Audi100 cross-wind stability, with course deviation after 2 seconds through cross-wind as evaluation index, and the conclusions are applicable to other automobiles with similar structure.
