Calculating Models and Simulink Analysis About Magnetorheological Damper

介绍了磁流变阻尼器的构造与性能及其常用的计算模型———Bingham模型和Bouc Wen模型 ,并提出了一个新的计算模型———Sigmoid模型。对三种计算模型进行仿真分析 ,并与试验结果进行对比研究 ,研究结果证明 :Sigmoid模型形式简单 。

The construction,behavior and ordinary calculating models about magnetorheological damper,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.
