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。
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.
