SIMULATION-BASED INVESTIGATION OF THE EFFECTS OF MAJOR PARAMETERS ON MAGNETORHEOLOGICAL BRAKE TORQUE

Abstract

In this paper, a magnetorheological brake (MRB) model that supports a van truck going downhill without interfering with the conventional braking system installed on this vehicle is designed and simulated. The simulation model demonstrates the impact of key variables on brake torque, including operation conditions, MRB tooth tilt angle, MRB rotor thickness, and MRB tooth count. As a result, the simulation results show that the maximum brake torque value is about 136.41 Nm at the 75-degree inclination angle of the tooth disk. The MRB rotor thickness does not have many effects on the brake torque. The maximum brake torque (138.7 Nm) can be achieved at 10 cm rotor thickness. The brake torque increases following an increase in the number of MRB teeth. The brake torque increases by 6% when the number of teeth increases from 1 to 3.
