摘要

摘要: 为了克服主动悬架耗能大的缺点，提出一种基于电动静液压作动器（electro-hydrostatic actuator，EHA）的自供能式主动悬架结构。分别建立了该系统主动模式和馈能模式下的数学模型，分析了EHA主动悬架系统实现自供能的能量平衡条件，设计了包含上层切换控制器和下层天棚控制器的分层协调切换控制策略，仿真分析了天棚阻尼系数对改善悬架性能和实现自供能的影响，并通过仿真分析设计了合理的天棚阻尼系数。结果表明，该EHA自供能式主动悬架系统改善了悬架动态性能，实现了能量自供能，有效克服了主动悬架耗能大的缺陷。

Abstract: Active suspension needs too much energy to generate an active control force. In order to overcome the shortcoming, a kind of self-powered active suspension system based on the EHA (electro-hydrostatic actuator) was proposed and designed. The models of the active mode and regeneration mode were respectively established. The energy balance condition of the EHA self-powered active suspension system was analyzed. The coordinated switching control strategies which included upper switch controller and lower sky-hook were designed. The effects of the sky-hook damping coefficient on improving suspension performances and realizing the self-powered were analyzed with the simulation method. And the reasonable sky-hook damping coefficient was designed. The results show that the self-powered EHA active suspension system can completely realize self-powered and improve the suspension performances, which effectively overcomes the defect of active suspension with high energy consumption.
