摘　　要：针对机械式两级串联“惯容-弹簧-阻尼”(ISD)悬架元件数量多、结构复杂等问题,提出一种对油气弹簧与惯容器融合设计的液压惯容悬架结构。首先,基于AMEsim搭建了整车模型并进行仿真分析;其次,研制了液压惯容悬架样机并进行了台架试验,验证了仿真模型的正确性。仿真和试验结果都表明,与双气室液压悬架相比,液压惯容悬架不仅能够降低车身与车轮的振动,改善车辆行驶平顺性和安全性,而且减小了悬架动行程。Aiming at the problems of mechanical two-stage series "inertia capacity-spring-damping"(ISD) suspension with a large number of components and complicated structure, a hydraulic inertia capacity suspension structure with a combination design of hydro-pneumatic spring and inertia container is proposed. Firstly, the whole vehicle model is built based on AMEsim and the simulation analysis is carried out. Secondly, the prototype of the hydraulic inertial suspension is developed and tested on the bench, which verifies the correctness of the simulation model. The simulation and test results show that compared with the double-chamber hydraulic suspension, the hydraulic inertia suspension can not only reduce the vibration of the vehicle body and wheels, improve the ride comfort and safety of the vehicle, but also reduce the dynamic travel of the suspension.
