摘　　要：针对空气制动可控性较差和响应速度较慢导致的停车不准、舒适度较差以及损耗较大等问题,研究列车全电制动技术。首先以全电制动的发展历程为基础,阐述全电制动应用的现状以及需要克服的主要问题,然后从高速和低速两个角度切入,详细介绍实现全电制动的难点问题及其所对应的解决思路,并针对每一个难点问题进行分析与总结,最后对全电制动未来的发展进行展望。Electropneumatic braking is the most common braking method adopted by most urban rail trains.However,the disadvantages of poor controllability and slow response of air brakes result in inaccurate parking and poor comfort.In addition,there are issues,such as greater losses.The solution to address these issues is to replace existing air braking with electric braking,which is an ideal solution.Based on the development history of full electric braking,this study elaborates on the current situation and the main problems that must be overcome in the application of full electric braking.From the perspectives of high and low speeds,this paper provides a detailed introduction to the difficulties in achieving full electric braking and their corresponding solutions.Each difficulty is analyzed and summarized,and future development directions are discussed.
