摘要

旋转涡流制动装置性能直接影响列车运行安全，基于旋转涡流制动装置动作时电磁场涡旋源密度的变化，从提高其安全性和可靠性入手，通过调整旋转涡流制动装置的气隙大小、转盘厚度、铁心磁导率、转盘磁导率、转盘电导率、不同电流和磁极排布方式等主要结构参数，并进行仿真和试验，可以达到提高制动力矩、减轻重量的目的。

Abstract

The performance of the rotatory eddy current brake device directly affects the safety of train operation. Based on the change of the electromagnetic field vortex source density during the operation of the rotatory eddy current brake device, for improving its safety and reliability, main structural parameters such as the air gap size, the thickness of the turntable, the magnetic permeability of the core, the magnetic permeability of the turntable, the electrical conductivity of the turntable, the different currents and the arrangement of the magnetic poles of the eddy current brake device was adjusted to improve the braking torque and reduce the weight by means of simulation and experiment.
