Design and Finite Element Analysis of Magnetic Circuit for Disk MRF Brake

Abstract

Design of magnetic circuit is the key for disk MRF brake and has an important effect on brake torque per unit mass. In this paper structure and working principle of disk MRF brake are introduced, and magnetic circuit is designed by using engineering magnetic field method, and main technologies are introduced in detail, and its magnetic field is analyzed based on finite element method. This is benefit for structure optimization of the magnetic circuit. The feather of the magnetic circuit is received by numerical analysis method, and magnetic saturation and leakage phenomenon are found at the circuit, and these problems should be paid attention especially.
