Abstract: In this paper, the MacPherson front suspension of a certain car is used as the research object, and the multi-body dynamics virtual prototype model of the McPherson front independent suspension of the car is established using ADAMS/Car, the simulation test of parallel runout of the double wheels was designed for the model. ADAMS/Insight optimizes the suspension design parameters, selects 9 hard-point coordinate values as design variables, and selects the main 5 suspension performance parameters (wheel toe-angle, etc.) as optimization targets, carries out sensitivity analysis and multi-objective optimization to obtain optimization after the hard point coordinate value. The results show that the performance of the optimized McPherson front independent suspension has been greatly improved, which has certain reference significance for the optimization design of the McPherson suspension in engineering.

摘要： 以某轿车麦弗逊式前悬架为研究对象，运用 ADAMS/Car 建立其多体动力学虚拟样机 模型，对该模型设计双轮平行跳动仿真试验，运用 ADAMS/Insight 对悬架设计参数进行优化 设计，选取 9 个硬点坐标值作为设计变量，选取主要的 5 个悬架性能参数（车轮前束等）作 为优化目标，进行灵敏度分析、多目标优化，得到优化后的硬点坐标值。结果表明，优化后 的麦弗逊式前独立悬架各性能均得到了较大幅度提升，对麦弗逊悬架在工程中的优化设计工 作具有一定的参考意义。
