摘  要

   隨著城市化進程的加快，越來越多的人們都在尋求更快捷、更環(huán)保的出行方式。城市軌道交通由于具有方便快捷、綠色環(huán)保等諸多優(yōu)點，受到了大家的廣泛青睞。而城市軌道列車的運營有別于干線鐵路車輛，它需要頻繁的啟動、調速、制動，這就對車輛制動系統(tǒng)的性能提出了更高的要求。

 1）為適應資源節(jié)約型和環(huán)境友好型社會建設的現實需要，城市軌道車輛所采用的制動系統(tǒng)應盡可能最大的利用電制動，它既能通過能量的回收而產生一定的經濟效益，又能減少閘瓦的機械磨耗而降低對環(huán)境的影響。 

2）為了適應短距離起停車的特點，必須使列車啟動快、 制動距離短。這就要求制動系統(tǒng)裝置具有操縱靈活，響應迅速，停車平穩(wěn)、準確和制動力大等特點。

 3）城市軌道車輛為動、拖車編組列車，所以要求編組列車的各車輛的制動能力盡可能一致，并且能夠適應列車乘客量的變化，具有空、重車的調節(jié)功能，以降低制動時列車的縱向沖擊。 

本論文主要講述了地鐵制動的類型、 地鐵車輛及列車制動系統(tǒng)的工作原理和工作過程。并分析了其的優(yōu)點和不足之處。

 ABSTRACT

With the speeding up of urbanization, more and more people are looking for a more efficient, more environmentally friendly way to travel. Urban rail transit with a convenient, green environmental protection, and many other advantages, is widely favored by everyone. And operation of urban rail train is different from the railway vehicle, it requires frequent start, speed control, brake, it's on the performance of the vehicle brake system put forward higher requirements.

1) in order to meet the reality of the construction of the resource-conserving and environment-friendly society needs, the urban rail vehicles, the maximum braking system should be adopted by the use of electric braking, it can through the energy recycling and produce certain economic benefits, and can reduce the mechanical wear of brake shoe and reduce the impact on the environment.

2）In order to adapt to the characteristics of short on parking, must make the train start fast, short braking distance. This requires a braking device is flexible, quick response and parking steady, accurate, and braking force big, etc.

3) for urban rail vehicle, trailer marshaling, so requires marshaling of each vehicle braking ability as consistent as possible, and the ability to adapt to the changing of the train passengers have empty and heavy vehicle adjust function, in order to reduce braking when the train longitudinal impact.

This paper mainly tells the story of the subway brake type, metro vehicle and train braking system working principle and working process. And analyzes their advantages and disadvantages.

Keywords: subway metro vehicle brake for the wind system and braking system working principle and working process
