Magnetorheological Brake (MRB), coil design, Torque-to-Mass Ratio (T/M), Finite Element Method (FEM)Abstract
This study investigates the impact of various coil parameters on the working efficiency of disc-form magnetorheological brakes (MRBs). While earlier research predominantly addressed coil shape and count, the present work examines less-explored factors, including coil installation position and conductor diameter. Finite Element Method (FEM) simulations were performed to analyze the relationships among braking torque, coil geometry, and applied current, with a particular focus on enhancing the torque-to-mass
ratio (T/M) to optimize both performance and cost-effectiveness. Results demonstrate that reducing the air gap between the coil and the MR fluid layer effectively concentrates magnetic flux, yielding a substantial increase in braking torque. The study offers comprehensive insights into coil design and configuration and proposes recommendations to improve MRB performance while maintaining economic feasibility.
