利用质量元件与惯容器之间的振动状态转换现象,提出理想地棚阻尼的被动实现方法,设计了被动地棚阻尼悬架,建立惯容器Simscape模型,采用物理拓扑网络方式构建整车Simscape模型,通过比较传统被动悬架、理想与被动地棚阻尼悬架系统性能,检验理想地棚阻尼被动实现方法的正确性与有效性。结果表明,被动地棚阻尼悬架系统能够抑制车轮共振,使轮胎动载荷均方根值减小30%以上,大幅提高了车辆的行驶安全性,与理想地棚阻尼悬架性能基本一致。

Based on vibration states transition between mass elements and inerters,a passive realization method for ideal ground hook damping was presented.According to such a method,a passive groundhook-damping suspension was designed.After the Simscape model of a inerter was built,the full-car Simscape model was established by using the network approach of physical topology.By comparing the performances of a conventional passive suspension and an ideal and passive groundhook-damping suspension,the correctness and effective-ness of the proposed passive realization method were verified.The results showed that the proposed passive ground hook damping suspension can be used to suppress wheel resonance,reduce RMS values of dynamic tire load by 30%or greater,and significantly improve the ride safety of vehicles,the performances of a passive groundhook-damping suspension are basically the same as those of an ideal ground hook damping suspension.
