摘　　要：根据某车型麦弗逊悬架结构提取硬点坐标,运用ADAMS/Car建立了汽车的麦弗逊前悬架虚拟样机模型,进行K特性仿真分析,通过ADAMS/Processor查看相应的变化曲线,分析了其定位参数主销后倾角、主销内倾角的变化范围。对于仿真结果中出现的变化范围过大的问题,采用ADAMS/Insight进行硬点的优化设计。优化后,由车轮跳动所引起的主销后倾角和主销内倾角的变化量都得到明显减小,且变化范围都在理想范围内,使整车性能得到提升。According to the structure of Macpherson suspension,the hard point coordinates are extracted,and the virtual prototype model of Macpherson front suspension is established by using ADAMS/car.The K-characteristic simulation analysis is carried out.The corresponding change curve is checked by ADAMS/processor,and the change range of the positioning parameters caster angle and kingpin_inclination_angle is analyzed.Adams/insight is used to optimize the hard point design for the problem that the change range of simulation results is too large.After optimization,the change of caster angle and kingpin_inclination_angle caused by wheel runout is obviously reduced,and the change range is in the ideal range,so that the performance of the whole vehicle is improved.
