摘　　要：汽车悬架中的车轮定位参数对提高汽车操纵稳定性具有重要意义。利用ADAMS软件自带的麦弗逊前悬架模块,选取车轮定位参数作为目标函数,通过ADAMS/Insight模块对悬架硬点进行灵敏度分析和改进,汽车主销后倾角范围由5.35°~5.60°减小到4.15°~4.35°,汽车主销内倾角变化范围由9.0°~11.3°减小到7.75°~10.25°。车轮定位参数得到明显优化。It is important to improve vehicle handling stability based on wheel alignment parameters in automobile suspension.Using the Macpherson suspension module brought by ADAMS software,the wheel alignment parameters are selected as objective function,the hard points on the suspension are selected for sensitivity analysis and improvement through the ADAMS/Insight model.The vehicle kingpin caster angle is reduced to 4.15°~4.35°from 5.35°~5.60°,and the vehicle kingpin angle is reduced to 7.75°~10.25°from 9.0°~11.3°.The wheel alignment parameters are optimized obviously.
