以汽车座椅和悬架系统的阻尼与刚度作为设计变量,综合考虑车辆的乘坐舒适性和对路面的损坏性,以座椅加速度均方根值和轮胎相对动载荷均方根值作为目标函数,建立被动悬架参数的两目标优化设计模型.提出多目标博弈设计方法,采用关联识别方法将设计变量集合分割为各博弈方战略集,给出基于Nash均衡博弈模型的多目标求解的计算步骤.对实际算例进行两目标博弈设计,计算结果显示博弈方法的有效性.

Taking the damping and rigidity of automobile seat and suspension system as design variables, the root mean square value of acceleration seat and relative dynamic loading of tire as objective function, two optimization design models of passive suspension parameters were established according to riding comfortableness and pavement breakage. It gave the method of multi-objective design based on game theory and the design variable set was divided into the strategic space owned by each game player by correlation recognition method. The calculation steps for solving multi-objective are established based on Nash equilibrium model. Taking actual two-objective for fuzzy optimization design, the results show that the method is effective.
