Abstract

To analyze the mechanism of the high-speed train eddy current braking device and optimize the design, established the basic structural model and derived the braking force equation. The magnetic circuit of it was analyzed by the analysis method and the finite element method (FEM). Mainly analyzed the influence of the air gap and the thickness of the turntable on the eddy current brake (ECB) electromagnetic field and the braking force, and the corresponding braking performance curve was obtained. There is some directive significance on the selection and optimization of the structural parameters of the eddy current braking device.
