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
