摘　　要：采用虚拟样机技术,利用机械系统动力学分析软件ADAMS建立了双横臂独立悬架的多刚体模型,并对模型进行仿真计算,得到了前轮前束角、前轮外倾角、主销后倾角、悬架刚度等定位参数在行驶过程中随车轮上下跳动的变化曲线。结果表明,在曲线平衡位置处,前轮前束角正处于零点;前轮外倾角略小于零,约为-0.03°,主销后倾角约为7.78°,主销内倾角约为9.4°,仿真模型的动特性与样车悬架的动特性基本一致,该方法可以准确地计算悬架的多种性能,提高了仿真精度和设计效率。The multi-body model of double-wishbone independent suspension was built by the use of virtual prototyping technology and the mechanical system dynamics analysis software ADAMS,the model was simulated to obtain the curve of toe angle,camber angle,caster angle and suspension stiffness orientation parameters with the wheels up and down in the car＇s movement process,in the equilibrium position of the curve,the toe angle is in the zero point;Camber angle is slightly less than zero,it is about-0.03°;caster angle is about 7.78°;kingpin inclination angle is about 9.4°.The simulation results compared with the prototype theoretical results show that the dynamic characteristics of the simulation models and the prototype vehicle suspension are basically the same,this method can accurately calculate the various performance of the suspension and improve the simulation precision and design efficiency.
