【摘要】 单出杆结构磁流变阻尼器因其阻尼力可控、结构简单等特点,成为结构半主动振动抑制应用研究的热点。由于补偿物理建模的复杂性,现有研究中一般未考虑附加刚度问题,仅有个别开展了相关试验研究。以浮动活塞-气室补偿单出杆磁流变阻尼器为研究对象,建立了阻尼器理论模型,分析了输出力的构成及影响因素,具有重要的实用价值。从示功特性角度,重点探讨了阻尼器附加刚度特性,为单出杆磁流变阻尼器设计提供重要参考。更多还原

【Abstract】 The single-ended Magneto-rheological(MR) damper with controllable damping and simple structure,has become one of hotspots in the fileds of semi-actively structure vibration.The auxiliary stiffness of MR damper is not fully covered due to the physical modeling complexity of compensation.Based on the MR damper with gas-floating piston compensation,the theoretical model was built to analyze the composition and influence factors of output force.,and which has important application value in MR damper design.In view of damping-displacement characteristics,the auxiliary stiffness of MR damper provides the reference for structure design.更多还原
