摘　　要：利用多体动力学软件ADAMS/CAR建立某轿车整车多体动力学模型。以悬架弹簧刚度和减振器阻尼系数作为设计变量,采用多目标遗传算法对车辆操纵稳定性及平顺性进行多目标优化。从优化得到的一组Pareto解集中获取最优解,结果表明该方法能有效优化汽车的操纵稳定性和行驶平顺性。A car multi-body dynamics model was built by using software ADAMS/CAR. The suspension spring stiffness and shock absorber damping characteristic were used as design variable,and the multi-objective genetic algorithm was used to perform optimization considering handling stability ride comfort. After optimization,a pareto set was obtained and an optimal solution was chosen from it,the result of analysis indicates that handling stability and ride comfort can be optimized effectively through this method.
