FE Analysis of Electromagnetic Braking Device Used in Disc Brake based on Maxwell

The paper briefly described the structure and principle of electromagnetic braking device used in disc brake. Electric vector potential and magnetic scalar potential were used to describe distribute of three-dimensional magnetic field of auxiliary electro- magnetic braking device of disc braking. A complete three-dimensional finite element model was established including algorithmic method of braking torque. With the three-dimensional transient solver of Maxwell software, the contours of the magnetic flux densi- ty and eddy current density of the device under stable working conditions were gotten. The characteristics and variation of the distri- bution of the magnetic induction and eddy current were analyzed. The brake torque was calculated at the same time. The results provided some references for practical design and optimization of electromagnetic braking device.
