摘　　要：为了更好地改善悬架的运动学性能,首先利用ADAMS/Car模块建立汽车麦弗逊前悬架模型,进行双轮平行跳动和异向跳动仿真试验,分析各定位参数在车轮跳动过程中的变化范围。然后利用ADAMS/Insight模块对前轮定位参数中的减震器上下支点、转向拉杆内外点、下摆臂外点等硬点坐标进行调整,对汽车前轮定位参数进行优化。结果显示,前轮前束角、前轮外倾角、主销后倾角和主销内倾角均达到了理想变化范围,其中,前轮前束角优化效果最为显著。In order to improve the kinematics performance of the suspension,first,ADAMS/Car module was used to build the McPherson front independent suspension model,and the suspension is simulated by parallel and opposite travel of two wheels.The change range of the positional parameters during the wheels travel is analyzed.Then some hard point coordinates such as Strut_lwr_mount/Top_mount,Tierod_inner/outer and Lca_outer in ADAMS/Insight module are adjusted to optimize the front wheel positioning parameters.The results show that the front wheel toe angle,camber angle,front wheel kingpin caster angle and kingpin inclination angle have reached the ideal range.The front wheel toe angle optimization is the most significant.
