摘 要: 依据国际大学生方程式赛车(formula society of automotive engineers,FSAE)规则要求提出一种设计赛车双横臂独立悬架的方法,并通过动力学仿真软件ADAMS对赛车悬架进行建模仿真,获得前悬架主销参数(主销后倾角、主销内倾角、车轮外倾角、前轮前束)及轮距随车轮跳动的变化情况,对仿真结果进行分析。应用ADAMS/Insight模块对悬架与车架的连接硬点进行灵敏度分析,通过改变最灵敏的硬点坐标值将主销后倾角变化范围从3.52°~5.23°优化至3.8°~4.8°,仿真结果证明悬架与车架连接硬点优化是优化主销参数的有效途径。

Abstract: This paper describes the design of double�wishbone suspension according to formula society of automotive engineers(FSAE)rules requirements. Using ADAMS software to model and simulate the suspension, the change of front suspension Kingpin parameters (Kingpin caster angle, Kingpin inclination angle, wheel camber angle and front toe) were obtained during the travel of the wheel, and the results of simulation were analyzed. Using ADAMS/Insight to analyze the sensibility of connection points (hard points) of the suspension, the range of caster angle was optimized from 3.52°~5.23° to 3.8°~4.8° through the change of the most sensitive hard point, which proved the optimization of connection points to be an effective way to optimize the kingpin parameters.
