Analysis of Torque in Magnetorheological Rotary Brake

Ping Wang, Jie Huang, Shu Hua Wei

Abstract

A magnetorheological (MR) rotary brake is a device that transmits torque by the shear stress of the MR fluids. In this paper, Bingham model is used to describe the constitutive characteristics of MR fluids subject to an applied magnetic field. The operational principle of the MR rotary brake is introduced. The torque transmitted by MR fluids is analyzed to compute the torque transmission ability in the MR rotary brake.
