摘要

针对被动液压互联悬架不能主动适应路况变化，提出一种能够调节车身高度的液压互联悬架系统。通过优化系统参数，使装有液压互联悬架车辆的垂向刚度基本和原车一致；采用分层控制理论进行车身高度调节的切换控制策略研究；基于CarSim、AMESim和Matlab/Simulink三个平台，搭建包含整车多体动力学模型和控制模型的联合仿真系统，并对切换过程、平顺性和操纵稳定性进行仿真分析。结果表明，该系统能够在不降低车辆平顺性的前提下，实现车身高度的按需调节，同时提高车辆的操纵稳定性。

Abstract

A height adjustable hydraulically interconnected suspension was proposed for actively adapting road condition changes. Parameters of the hydraulically interconnected suspension were optimized to make the vertical stiffness of a vehicle with this suspension keep the same as that of the original vehicle. Based on the hierarchical control theory, a switching control strategy for the height adjusting of vehicle body was adopted. based on CarSim, AMESim and Matlab/Simulink simulation platforms，a joint simulation system including a vehicle multi-body dynamic model and a control model was established. The simulation analyses for switching processes, ride comfort and handling stability were performed. The results indicated that this system is able to adjust adaptively the height of vehicle body, and improve the handling stability of vehicle, in the premise of simultaneously keeping vehicle’s ride comfort.
