摘　　要：为了改善车辆悬架参数特性,提高整车的操纵稳定性,提出响应面和多目标两种方法对悬架参数进行优化设计。首先在ADAMS/CAR建立带有转向系统的麦弗逊式悬架仿真分析模型并进行双轮同向仿真试验,其次,在ADAMS/Insight对悬架特性参数进行灵敏度分析筛选出对车轮定位参数影响比较大的前6位设计因素,然后采用响应面和多目标方法分别对悬架特性参数进行优化求解,最后将两者求得的最优解参数带回悬架模型中再次在ADAMS/CAR中进行对比仿真试验分析,验证了多目标优化方法的优越性。To improve the characteristics of suspension parameters and steering stability of the vehicle,response surface and multiobjective methods are used to further optimize the suspension parameters. The simulation model of Mc Pherson suspension with steering system is set up in ADAMS/CAR,and the co-simulation test is carried out for the two wheels,then,the sensitivity of the suspension is analyzed in ADAMS/Insight to choose front six design factors and the response surface and multi-objective methods are used to optimize the suspension parameters respectively,then,the optimum parameters are applied in the suspension model in ADAMS/CAR again to do the simulation analysis and verify the advantage of the multi-objective optimization method.
