摘　　要：以某厂家设计的前麦弗逊悬架为例,在ADAMS/Car中建立其运动学模型,以前轮定位参数在轮跳时的合理变化范围为目标函数,以麦弗逊悬架的下控制臂、转向横拉杆及减振器的几何定位参数为设计变量,建立了二阶响应面模型并进行了优化计算.结果表明基于响应面模型的车轮定位参数优化方法效果明显.Taking the Mcpherson suspension as an example, its kinematics model in ADAMS/Car is built up in the paper. The two order response surface model is established and the optimization is calculated using the reasonable range of front wheel alignment parameters as objective function, the geometric position parameters of steering tie rod and damping and the lower control arm as parameters. It was indicated that the approximate model technology was an effective method for optimizing on wheel alignment parameter.
