对一种新型电磁阀式阻尼连续可调减振器进行了研究,分析了其结构特点与工作原理,建立了复原行程和压缩行程的液压模型与数学模型,对其阻尼特性进行仿真;同时在单通道电液伺服悬架动态性能试验台上进行试验.仿真结果与试验数据基本吻合,说明所建立的电磁阀式减振器模型较为准确,可用于电磁阀式阻尼连续可调减振器的研究与开发.%A new type of solenoid-actuated shock absorber with continuously variable damping is studied. Its structural features and working principle are analyzed, the hydraulic model and the mathematic model for compress and rebounce strokes are established and its damping characteristics are simulated. Meanwhile a corresponding test is also conducted on a single-channel electro-hydraulic servo tester. The results of simulation agree well with test data, indicating that the model established for solenoid-actuated shock absorber is relatively accurate and can be used for the research and development of solenoid-actuated shock absorber with continuously variable damping.
