Abstract

This paper provides an annular groove Magnetorheological(MR) brake. Bingham model is used to describe the constitutive behavior of MR fluids subject to an applied magnetic field. The theoretical analysis of the shear flow and braking torque of MR fluid between two parallel annular disks in annular groove MR brake is presented. The performance experimental system of brake is established to test the properties of annular groove MR brake. Based on the braking torque equation, the expression for the minimum active fluid volume and gap of MR fluid exposed to the magnetic field between two parallel annular disks is derived to provide the theoretical foundation for the key geometric design in annular groove MR brake. Based on the function of brake, the design elements and methods of an annular groove MR brake are established. The results indicate that the braking torque greatly influenced by the magnetic flux density. Under the premise of given braking torque, the speed and control torque ratio, a designer can select the MR fluids, calculate the effective gap and volume, draw the desired function diagram.
