摘　　要：本文应用汽车动力学分析软件ADAMS/Car建立了某前置前驱SUV车的麦弗逊式前悬架模型,并对该前悬架模型进行了虚拟试验平台仿真试验。仿真结果显示在车轮上下跳动过程中,该麦弗逊悬架的车轮外倾角、主销后倾角、注销内倾角和前束角等悬架定位参数表现欠佳。应用ADAMS/Car中的Insight模块对前悬架结构进行优化以改善其定位参数,结果显示优化后前悬架模型的定位参数得到了改善,依据国家标准进行的仿真试验也显示整车操纵稳定性得到了提升。本文提出的优化方法可以为麦弗逊式前悬架的设计提供支持。A Macpherson suspension model of a front-engine-front-drive car is built in ADAMS/Car.A parallel wheel travel simulation is done and some defects are found in the parameters of suspension(such as camber angle,toe angle and so on).This paper describes a way to optimize the suspension performance.The result proves that the suspension performance and vehicle handling stability performance have been improved according to the national testing standard.The method can be applied to optimal design of Macpherson suspension.
