Abstract:

An electromagnetic brake with new structure was studied in this paper. The electromagnetic braking torque can be improved as the air gap width can self-regulate with the change of temperature. The heat conduction model, air gap width model and electromagnetic braking torque model were established. The structure parameters of the electromagnetic brake were optimized, including the air gap width, the size of the iron-core and the thermal-deformation component. The finite element model of the electromagnetic brake was established in ANSYS, which was used to research the temperature change of the brake. The long downhill condition and emergency braking condition were studied by simulation. The change of the air gap width was analyzed in Matlab. The current requirement of the new electromagnetic brake was compared with that of an old brake in the same brake task. The results show that increasing the air gap width of the self-regulation structure, the new electromagnetic brake can smoothly work in the long downhill braking condition and emergency braking condition, when the air gap width is 0.4 mm to 1 mm. The brake torque of the new electromagnetic brake is increased significantly.

Key words: vehicle engineering, electromagnetic brake, air gap, temperature compensation, structural parameters optimize
