摘　　要：通过对麦弗逊悬架系统的模型进行简化,建立前轴1/2汽车模型,确定以主销内倾角、主销后倾角、前轮外倾角、前轮前束、前轮接地点侧向滑移量的变化情况作为汽车操作稳定性评价指标。导入UG模型并运用ADAMS进行仿真,分析下摆臂的长度变化量、摆动位置(侧倾角、仰倾角)对这五个评价指标参数的影响情况,并对其进行插值拟合,得出关系式,对研究汽车操作稳定性影响因素、悬架主要零件下摆臂的结构参数设计具有一定的参考价值。By simplifying the model of McPherson suspension system,the front axle 1/2 car model is establishedin this article,and the kingpin inclination angle,the kingpin back inclination angle,the front wheel camber angle,the front wheel front beam and the lateral slip of the front wheel contact point are determined as the evaluation indexes of automobile operational stability.The UG model is imported and the ADAMS is used for simulation so as to analyze the influence of length change of the lower control arm on these five evaluation index parameters;then it is used for interpolation fitting to obtain the relationship,which has certain reference function to study the influence factors of automobile operation stability and design of structural parameters of the bottom swing arm,the main part of suspension.
