| 摘 要： | 为了提升整车操纵稳定性和舒适性,采用理论分析和实车试验相结合的方法探讨了车轮偏心对转向盘摆振的影响。从理论上分析了车轮偏心引起的激振力和车轮动不平衡对转向盘摆振的贡献;以某B级车为研究对象,进行了多个因素的对比试验。结果表明:调整车轮动平衡对转向盘摆振稍有影响,调整下摆臂后衬套也有一定影响,但都不能明显减小振动加速度幅值;调整车轮偏心对转向盘摆振有显著影响,调整车轮偏心后,振动加速度幅值减小了近2倍;车轮偏心比动不平衡对转向盘摆振的影响更大,通过调整车轮安装定位方式消除安装偏心,对转向盘摆振现象的改进效果明显。

| Abstract: | In order to enhance vehicle handling stability and traveling comfort,influence of wheel eccentricity on steering wheel shimmy was discussed based on theoretical analysis and field vehicle test.Regarded level B vehicle as research object,comparison tests of prototype were carried out after analysis of steering wheel shimmy caused by eccentric forces of wheel and unbalance mass.Results show that compared with the dynamic balance adjustment of wheel,the bushing adjustment of swing-arm has more effect on steeri... |
