Temperature-Dependent Normalized Bouc-Wen Model for MR Damper

A temperature-dependent normalized Bouc-Wen model is proposed to describe the hysteresis and temperature characteristic of magneto-rheological (MR) damper. The MR damper is warmed up through long-term continuous experiments and the model parameters are identified using experimental data. The least-squares method and Genetic Algorithm (GA) are utilized to identify the parameters at different temperatures. Also, the relationship between parameters and temperature is established to describe the nonlinear temperature model of the MR damper.
