A Parameter Identifying Method for Magnetorheological (MR) Fluids Dampers

In order to speed up the commercial process of magnetorheological(MR) dampers, it is necessary to set up the theoretical foundation of the design of MR dampers. In this thesis, we studied the mechanical property of MR fluids, the design roles of MR dampers and the experimental modeling of MR dampers. Based on a prototype MR dampers working in flow mode, an experimental modeling method for MR dampers is put forward. Employing a nonlinear sequential filter to identify the model parameter of viscous plastic model carries out the modeling method.We performed numerical simulation with eqs. (5) and (7), present the simulation results in Fig.3. The good agreement between the test data and results computed shows that the modeling method is correct
