摘　　要：建立了四连杆式悬架多刚体系统模型,并对车轮定位参数等特性进行了仿真,运用多目标函数的最优化方法对悬架的结构参数进行了优化,将优化前后的车轮定位参数运动学特性进行了对比,结果表明,悬架结构参数的优化对提高悬架性能具有重要作用。The multi-body system model of four-link rods type suspension is set up and the characteristics of wheel alignment parameters is simulate in this paper. The structural parameters of the suspension by using the method of multi-objective function are optimized and the kinematics performances of wheel alignment are compared, which indicates that the optimization of the suspension structural parameters is very useful to improve characteristics of suspension.
