摘要

为进一步拓宽应用惯容器的车辆悬架结构设计思路,基于“惯容器-弹簧-质量”系统的反共振,以并联的“惯容器-弹簧”二元件为结构基础,构建出两种不同的车辆ISD悬架结构。通过遗传优化算法得到悬架的结构参数,在频域范围内对比分析了传统被动悬架、Ⅰ型悬架和Ⅱ型悬架系统性能,结果表明,所构建的悬架结构可有效抑制车身偏频处的振动。最后,对性能较优的Ⅱ型悬架开展试验研究,搭建了含有Ⅱ型悬架结构的车辆四分之一悬架试验台架,在随机路面输入下对悬架平顺性评价指标进行定量分析。其中,悬架动行程均方根值最高提升16.24%,轮胎动载荷均方根值最高提升6.75%,车身加速度均方根值也略有改善。说明所设计的悬架结构可有效改善车辆的行驶平顺性与操纵稳定性。

Abstract

In order to further broaden the design thought of vehicle suspension applying inerter, two types of vehicle ISD suspension have been designed based on the two parallel elements‘inerter and spring’ by using the anti-resonance of the inerter-spring-mass structure. Using genetic algorithm to get the optimized structural parameters of suspension, analysis in frequency showed that, compared with the passive suspension, the designed suspension structures can suppress the vibration at the offset frequency of the body resonance. Experiment on the second generation suspension has been carried out, a quarter vehicle suspension test bench including the second suspension structure has been built. In the random road input, the suspension working space square mean root has improved by 16.24%, the dynamic tire load square mean root has improved by 6.75%, and the body acceleration square mean root has also improved. The results show that the designed suspension structure can effectively improve ride performance and control stability.
