Research on MRD Parametric Model Based on Magic Formula

Abstract EN

In order to get a better description to the nonlinear characteristics of magnetorheological dampers, the magic formula is introduced into the general method of parametric modelling of magnetorheological dampers to propose a new parameterized model called magic formula-hysteresis loop model (MFM).

The new model is simple in structure, the physical meaning of each parameter is clear, and the parameter identification is convenient.

The fitting and experimental data of MFM and the phenomenon model under different conditions are applied for error analysis and comparison.

The results show that the errors of MFM are more accurate and have better fitting and experimental data under different working conditions, which also have better adaptability and versatility.
