Abstract
Due to the complex electromagnetic field changes in the eddy current braking system, it is difficult to calculate directly. In this paper, the eddy current braking system for high-speed maglev train is taken as the research object. For the dynamic change of skin effect caused by high-speed maglev train eddy current brake at different running speeds, the mathematical model of eddy current brake is established, and the model is solved by finite element method. The delamination equivalent model is refined according to the relationship of penetration depth caused by skin effect at different velocities. Considering different air gaps, different excitation conditions and conductor plate material, the model is calculated to evaluate the eddy current braking performance, which provides a reference for the design of eddy current braking system for high-speed maglev train.
