中文摘要：

为了研究赛车的操纵稳定性,应用机械系统动力学软件ADAMS,对前悬架进行建模和运动学仿真分析,对悬架结构型式进行调整。选取适当的硬点坐标作为优化变量,基于ADAMS/Insight模块,针对前轮前束的变化进行优化设计,最终改善了赛车的操纵稳定性。对于运动型车辆的前悬架设计具有一定的指导意义。

英文摘要：

To research the handling stability of racing cars,the double wishbone front suspension of FSAE racing car is modeled and simulated based on the software ADAMS（Automatic Dynamics Analysis of Mechanical System）;and the suspension structure is modified.Aiming at the change of TOE,the proper hard points are selected to be the variables and optimization is realized based on ADAMS/Insight.The car＇s handling stability is improved greatly.The essay is helpful in designing the front suspension of racing car.
