Abstract

In order to improve the yield stress of magnetorheological fluids, compression working mode of MRF was applied and mechanical property of MRF micro structure under compression working mode was researched. The form of particles chains was divided into thre e states and mechanical property of each state was analyzed based on magnetic dipole theory. Analysis results show that the position of particles chains and attached particles play an important role in the mechanical property o f MRF micro structure. Finall y, a numerical simulation example was provided and comparison results indicated that the proposed analysis was accurate..
