The effect of surface roughness on the stick-slip motion of Magnetorheological (MR) fluids under a simple linear shear mode has been experimentally reported. The shear stress of the MR fluids could be modulated by the changing of the surface roughness. The rate of energy accumulation and releasing during stick-slip motion changed with respect to the shear plates of different surface roughness. The changing of the stick-slip motion based on the different surface roughness was ascribed to the evolution of internal particle structures when shear motion was applied to the aggregates of the particles exposed to the external magnetic field.
