Modeling and Analysis of Magnetorheological Fluid Damper under Impact Load

Abstract:

Modeling of a multi- ring grooves Magnetorheological（MR）fluid damper designed by ourselves were respectively carried out based on the Bingham model and the Herschel-Bulkley model. By comparing the simulation results of the two models with the true drop experimental result, it was proved that the Herschel-Bulkley model is in good accordance with the experiment and outperformed the Bingham model under high shear rate and high magnetic field. Furthermore, the parameter n in the Herschel-Bulkley model reflects the densification of the MR fluids, and by identifying and selecting the value of n better models and simulation results can be obtained.
