摘　　要：制动作为高速列车的重要组成部分,一直是制约列车动力及运行安全的关键因素。实现同步制动是增强高速列车的安全性能、提高运能的关键。比较了目前实际应用的各种制动方式和制动技术,分析了各自优缺点。为了实现同步制动,设计了机电磁一体化的转定转三层结构,研制了一种双环外桶复式同步涡流制动机。该装置可通过控制励磁电流调节制动力大小,实现了宽速度(5~700 km/h)同步制动的目的,为增强高速列车的安全性能、降低摩擦耗损带来技术选择性突破。As an important part of high-speed train,braking is always the key factor restricting the train’s power and running safety.The realization of synchronous braking is the key to enhance the safety performance and the transportation capacity of high-speed trains.In the paper,the various braking modes and technologies applied at present were compared,and their advantages and disadvantages were analyzed.In order to realize the synchronous braking,an electromechanical magnetic integrated rotating-stating-rotating three-layer structure was designed and a double-ring external barrel compound synchronous eddy current brake was developed.The device can adjust the braking force by controlling the field current,so as to achieve the purpose of synchronous braking at a wide speed(5-700 km/h),and bring a technical selective breakthrough for enhancing the safety performance of high-speed trains and reducing friction loss.
