摘　　要：针对某电动导览车的前轮胎磨损明显的现象进行前轮定位参数的优化分析和悬架的改进工作。运用ADAMS/Car模块创建了该车转向系统与双横臂独立前悬架系统的动力学分析模型,对该模型仿真分析,可得在行驶过程中主销后倾角、主销内倾角、前轮前束角、外倾角等前轮定位参数随着车轮上下跳动过程中的变化。为了使优化过程更加高效,应用ADAMS/Insight找出对定位参数影响中灵敏度较大的硬点坐标,并针对该车的实际工况,对这些点坐标进行优化。将优化前后的定位参数变化曲线进行对比,分析优化的效果。运用优化结果,可以改善原车悬架与转向系统存在的问题。According to the front-wheel wear and tear problem of one electric sight-seeing car, it optimized cdignment parameters of front wheel to improve the problem. It established a dynamics model of front suspension and steering system by ADAMS/Car. The model was analyzed by simulation to get wheel alignment parameters ： the front wheel camber angle, caster angle, kingpin inclination angle, and toe angle changed with the wheel center beating itinerary. In order to improve the efficiency, it used ADMS/Insight to find the hard point coordinates which hod higher sensitivity. Then optimized the point coordinates. Comparing the curve of alignment parameters before and after optimization, it analyzed and identify the inadequacies of the front suspension.
