摘　　要：为研究汽车在高速行驶中的侧风稳定性,应用MSC Adams/Car建立某型燃料电池汽车的整车模型,考查该车的抗侧风稳定性,并分析影响其侧风稳定性的主要因素.通过使风压中心后移、增加整车质量以及控制车体侧向面积和降低形心等手段,可以提升整车抗侧风稳定特性.To study the cross wind stability of vehicle when it is drived at high velocity, the whole vehicle model of a fuel cell car is established by MSC Adams/Car. The overall performance of the prototype fuel cell car is studied and main factors that affect its cross wind stability are specified. The cross wind stability performance is improved by moving backward location of wind pressure center, increasing gross mass, controlling side area, and decreasing centroid.
