针对两级惯性弹簧阻尼器（ISD）机械悬架存在的悬架元件过多、结构复杂、工程实现困难等问题，提出了一种集成油气弹簧和惯性器的油气两级ISD悬架。基于AMESim软件建立了油气ISD悬架的整车模型。仿真分析表明，所提出的悬架的有效性和性能。开发了液空ISD悬架原型，并在四柱轮胎耦合道路模拟器上进行了测试。结果表明，与单气室油气悬架相比，ISD油气悬架能显著降低车身和车轮的振动，但悬架工作空间过大。相比之下，虽然提出的悬架也是一种双腔液压气动悬架，但它不仅可以减少这些振动，而且还可以缩小SWS的尺寸，这意味着它是更舒适和更安全的最佳选择。
To address the problems of mechanical two-stage inerter-spring-damper (ISD) suspension such as excessive suspension elements, complex structure, and problematic engineering implementation, a hydro-pneumatic two-stage ISD suspension, which integrates hydro-pneumatic spring and inerter, is proposed. The full vehicle model of hydro-pneumatic ISD suspension is established based on the AMESim. Simulation analysis is performed to demonstrate the effectiveness and performances of the proposed suspension. The hydro-pneumatic ISD suspension prototype is developed and tested on four-poster tire-coupled road simulator. The results suggest that, compared with single-chamber hydro-pneumatic suspension, the hydro-pneumatic ISD one can significantly reduce the vibrations of the vehicle body and wheels, but at the expense of an excessive increase of suspension working space (SWS). In contrast, although proposed suspension is also a type of dual-chamber hydro-pneumatic one, it can not only reduce these vibrations but also downsize the SWS, which means it is the best choice for a more comfortable and safer ride.
