Abstract

The operational principle of a circular plate magnetorheological (MR) clutch is introduced. The Bingham model is used to describe the constitutive characteristics of the MR fluids between two circular plates subject to an applied magnetic field. Associated with geometric shape and applied magnetic field onto the clutch, the mathematical model to transmit the torque is established. The expressions of the torque and the output speed are derived to provide the theoretical foundation for the analysis of the clutch. The numerical results indicate that the MR clutch transmits the torque by the shear stress of the fluid. The torque and the output speed can be controlled continuously by changing the strength of the applied magnetic field. With the increase of the gap between two circular plates, the torque decreases.
