A New Magneticrheological Damper Nonlinear Bingham Hysteretic Model and ANSYS Implementation

Abstract:

In this paper, firstly, a new nonlinear Bingham hysteretic model is established by studying on the Test results of damping force characteristics of the magneto rheological fluid. The model not only can simulate the damping characteristics of the magneto rheological damper very well, but also can well describe the relationship between damping and velocity with the small velocity, and has fewer parameters by compared with other magneto rheological damper model. Secondly, based on nonlinear least square method, the parameters with different current are recognized and the relationship between the parameters and current is defined, then the mechanical model is theoretically verified. Furthermore, the mechanical model is simulated by ANSYS, the data obtained agree well with the calculated value.
