摘　　要：为探讨双桥货车动力学特性兼顾平顺性和路面损伤的优化方法,建立了车辆动力学模型,用总加权值法求解车体加速度均方根以评价车辆平顺性,用全概率法评价车辆对路面的损伤,构造了包括目标泛函、设计变量和约束条件的悬架参数优化设计模型。对FAW110货车前后悬架阻尼和刚度优化后,路面损伤和平顺性分别改善6.2%和29%。The dynamics character optimum considering both compliance and pavement damage of two axles truck is discussed. A dynamic vehicle model is created. Total weighing value method is used to evaluate the vertical compliance of the vehicle, and full probability method is used to evaluate the damage of pavement by the vehicle. The optimizing model includes aiming functional, design parameter and limiting condition. When this method is used to optimize the suspension parameter of the duty vehicle of FAW110, its compliance and pavement damage were improved by 6.2% and 29 % respectively.
