[提要] 介紹了磁流變阻尼器的構(gòu)造與性能及其常用的計算模型-Bingham模型和Bouc-Wen模型，并提出了一個新的計算模型- Sigmoid模型。對三種計算模型進行仿真分析，并與試驗結(jié)果進行對比研究，研究結(jié)果證明：Sigmoid模型形式簡單，易于程序化且能很好地描述磁流變阻尼器的力學(xué)性能。
[關(guān)鍵詞] 磁流變阻尼器 計算模型 Sigmoid模型The construction, behavior and ordinary calculating models about magnetorheological damper,落千丈including Bingham model and Bouc-Wen model, are introduced, and a new model-Sigmoid model is proposed. Simulink analysis about three models is made, and the simulink results and the test results are compared. Study results show that Sigmoid model has simple form,is easy to programrize and can embody the mechanical behavior of magnetorheological damper perfectly.
Keywords: magnetorheological damper; calculating model; Sigmoid model
