利用Routh稳定性准则和Pade逼近技术对被动天钩阻尼悬架系统进行简化，建立了包含降阶ISD悬架的整车模型，并对其平顺性进行了分析。采用统一目标函数的遗传算法对结构参数进行优化。对传统被动悬架、被动天钩阻尼悬架和降阶ISD悬架的系统性能进行了对比分析。结果表明：降阶ISD悬架的车身加速度、轮胎动载荷和悬架工作空间的均方根值与被动天钩阻尼悬架接近，能够实现其主要性能；研究结果表明，减阶ISD悬架的整体性能可以接近被动天钩阻尼悬架，从理论上验证了减阶ISD悬架的有效性。在此基础上，研制了一种将减振器与减振器串联的综合减振器装置，并将其安装在越野车的前后悬架上进行道路试验。研究结果表明，减阶ISD悬架能有效抑制车身的垂直、俯仰和侧倾振动。
With the use of Routh stability criterion and Pade approximation technique to simplify the passive skyhook damping suspension system, a full-car model involving the reduced-order ISD suspension was established for the analysis of ride comfort. The genetic algorithm of unified objective function was applied for the optimization of structural parameters. Comparative analysis of the system performance was conducted among the conventional passive suspension, the passive skyhook damping suspension and the reduced-order ISD suspension. The results show that the root-mean-square value of body acceleration, tire dynamic load and suspension working space of the reduced-order ISD suspension are close to those of the passive skyhook damping suspension and the main performance can be achieved. It illustrates that the overall performance of the reduced-order ISD suspension can be close to the passive skyhook damping suspension and the research theoretically verified the effectiveness of the reduced-order ISD suspension. Furthermore, a integrated inerter device with inerter and damper connected in series is developed, which is then arranged in the front and rear suspension of an off-road vehicle for road test. As a result of this paper, it was demonstrated that, the reduced-order ISD suspension can suppress the vertical, pitch and roll vibration of vehicle body.
