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.
