Study on Damping Force of MRF Damper Based on Bingham Model

Qingliang Zhang

Abstract

Working characteristics of magnetorheological fluid(MRF) damper was introduced.Various models to construct damping force were summarized.The structure schematic of MRF damper used in the study was provided.Key factors of solving damping force were stated.Based on Bingham model,damping force formulas of MRF damper working in flowing mode and shearing mode were derived after unfolding damping clearance to parallel plate.The relevant damping force models were constructed.The effect of current variance on damping force was compared,and simulation results were provided.
