摘　　要：研究了一种直线感应式的轨道涡流制动器,该制动器不同于传统的直流励磁涡流制动器和永磁涡流制动器,而是以三相交流励磁来产生气隙磁场;相较直流励磁和永磁涡流制动器来说,其有着制动力平稳,低速仍有较高制动力的优点。本文详细介绍了直线感应式轨道涡流制动器的基本原理以及基本结构,并通过有限元法对影响该制动器制动性能的电磁参数以及机械参数,比如运行速度、气隙大小、励磁电流、励磁频率等进行了相应的仿真计算,为轨道涡流制动器的研究提供了参考价值。A linear induction type rail eddy current brake was researched,this brake is different from the DC excitation eddy current brake and permanent magnet eddy current brake,but uses three-phase AC excitation to generate magnetic field in air gap.It has the advantages of smooth braking force and high braking force although low speed.This article introduced the basic principle and structure of the linear induction type rail eddy current brake in detail,and through the finite element method,corresponding simulation calculation of the electromagnetic parameters and mechanical parameters that affect the braking performance of the brake,such as operating speed,air gap,excitation current,excitation frequency was carried out,which provided reference value for the research of rail eddy current brake.
