Application of Electro-Mechanical Braking System in Metro Train

地铁列车空气制动系统存在电能转化成空气压力能的中间环节,限制了制动响应速度和控制精度的进一步提高。探讨了一种应用于地铁列车上的直接采用电能驱动摩擦副的电机械制动技术。介绍了电机械制动系统的组成原理、系统方案,并分析了其使用特点。相比于空气制动系统,电机械制动系统简化了结构,提高了可靠性,可实现地铁列车制动动力源、制动控制和制动执行的分布化、全电气化和高度智能化。

The intermediate link of converting electrical energy into air pressure energy in metro train air braking system might limit the further improvement of braking response speed and control accuracy.In this paper,the application of electromechanical braking technology to metro train is discussed,which directly uses electric energy to drive the friction pair for metro train.The composition principle and system scheme of electromechanical braking system are introduced,the application characteristics of which are analyzed.Compared with the air braking system,the electromechanical braking system simplifies the system structure,improves the system reliability,and therefore can realize the distributed design,full electrification and high intelligence of metro train breaking power source,braking control and execution.
