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”系统反共振，以并联的“惯容器-弹簧”二元件为结构基础构建两种不同车辆 ISD 悬架结构。通过遗传优化算法获得悬架结构参数，在频域范围内对比分析传统被动悬架及Ⅰ、Ⅱ型悬架系统性能。结果表明，所建悬架结构可有效抑制车身偏频处振动。对性能较优Ⅱ型悬架进行试验研究，搭建含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定量分析。悬架动行程均方根值提升16．24％，轮胎动载荷均方根值提升6．75％，车身加速度均方根值略有改善。表明该悬架结构能有效改善车辆的行驶平顺性与操纵稳定性。

In order to further broaden the idea of vehicle suspension structure design with the application of inerters,two types of vehicle ISD suspension have been designed based on the two parallel elements of ‘inerter and spring'in the light of the anti-resonance property of inerter-spring-mass structure.The genetic algorithm was used to get the optimal structural parameters of suspension,a frequency a contrast analysis in frequency domain was carried out to compare the performances of different types of suspension structures.The results show that,compared with the passive suspension,the designed suspension structures can suppress the vibration in the offset frequency bands of the body resonance.Investigation experiments on the second generation suspension structures were conducted and,a quarter vehicle suspension test bench including the second type of suspension structure was built.Under the random road signal excitation,the root mean square of the suspension working stroke is improved by 16.24%,the root mean square of the dynamic tire load is improved by 6.75%,and root mean square of the body acceleration is also somewhat improved.The designed suspension structure can effectively improve ride performance and control stability.
