摘要
针对某项目开发的电动汽车样车在行车试验时存在因前轮侧滑量偏大而引起轮胎磨损较大的问题。在ADAMS/Car模块中建立了麦弗逊式前独立悬架虚拟样机模型,基于灵敏度分析,找出了影响前轮定位参数的主要物理量,建立了前轮定位参数与悬架布置方案之间的关系,并据此对麦弗逊式前独立悬架的布置方案进行优化。基于优化后的悬架布置方案,在ADAMS/Car模块中建立了整车虚拟样机模型,并进行了稳态回转仿真试验。试验结果表明,该车存在转向不足特性,悬架优化前后对整车的稳态回转性能影响不大。
In order to solve the problem of the electric vehicle＇s tire was worn badly caused by the high levels of front wheel skid,Macpherson suspension virtual prototyping model was established in ADAMS/Car module.Based on sensitivity analysis;mainly quantities that affect front wheel positioning parameters was found.The relationship between front wheel positioning parameters and the arrangement of Macpherson front independent suspension was established.Macpherson suspension layout scheme optimization was carried out based on this.Based on the optimized suspension layout,virtual prototype model was established on the ADAMS/Car module.Steady rotation simulation test was carried out.The results show that the car with insufficient turning,and steady turning performance with no obviously variation before and after suspension optimization.
