Abstract: From the 5th International Conference on Electrorheological Fluids,Magnetic Suspensions and Related Technologies, it can be seen that important progresses have been made in application researches on both electrorheological (ER) and magnetorheological (MR) fluids. The shear stress of MR fluids is one order of magnitude higher than that of ER fluids, so more attention has been paid recently to the research on MR fluids, The surface effect of ER fluids, and the influence of energy loss to the ER effect are i...
