| 摘 要： | 通过ADAMS/CAR建立一麦弗逊前悬架刚弹耦合模型,运用ADAMS/insight对悬架橡胶衬套刚度进行了灵敏度分析。选取对车轮定位参数影响较大的衬套刚度作为设计变量,以车轮外倾角、前束角、主销内倾角、主销后倾角的变动量最小为目标函数,应用试验设计和多目标优化方法来改进车轮定位参数。研究结果表明,改变下控制臂轴上的前衬套轴向刚度、扭转刚度,后衬套径向刚度、轴向刚度、扭转刚度能有效改进悬架的运动学特性。经过优化设计后,悬架性能较原方案明显改善。

| Abstract: | A rigid-flex coupling model of McPherson suspension system based on ADAMS/CAR is built.And the stiffness sensitivity of suspension rubber bushing stiffness is analyzed with the software ADAMS/insight.Then the rubber bushing stiffness that affects significantly on the wheel alignment parameters is selected as the design variables,and the minimum variation of the wheel alignment parameters,such as the camber angle,the toe angle,the kingpin inclination angle,the caster angle,is taken as the objective functions... |
