摘　　要： 针对处在试验研制阶段的电动汽车,为了满足安全行驶的需要,基于电动汽车操纵稳定性的考虑,对电动汽车底盘的布置方案进行优化。针对电动汽车样车在行车试验时存在前轮侧滑量偏大引起轮胎磨损较大的问题,基于灵敏度的考虑对悬架的布置方案进行了优化。在AD-AMS/Car模块中建立优化后的整车虚拟样机模型,通过改变电池摆放位置和承载大小来观察整车操纵稳定性的变化,从而得到最优的汽车底盘布置方案。 In accordance with electric cars in development and experiment stage,in order to meet the driving safety need of electric cars,and based on the considerations of electric vehicle handling stability,a electric car chassis layout scheme was optimized.To solve the problem which the electric vehicle＇s tires were worn badly because of the high levels of front wheel skid,the arrangement of suspension was optimized based on sensitivity analysis.A virtual prototype vehicle Model was established on the ADAMS/Car Module.The changes of the vehicle steering stability were observed by changing position of the battery and size of bearing toget the optimal automobile chassis layout.

关 键 词： 操纵稳定性 底盘 布置方案
