270km/h高速机车自密封门的开发研究

Development of Self - airproof Side - door in 270 km/h High - speed Locomotive

介绍了一种用于270km/h高速机车的转臂连接折页式自密封侧门。该门结构简单、操作方便,可利用列车高速运行时作用于门上的负压,使门产生自密封作用,负压越大,密封效果越好。

A new kind of self- airproof side - door in 270km/h high - speed locomotive was developed.The side - door connected to the doorframe by rotating beams via hinges was very simple and can be Operated conveniently. The negative pressure on the door produced by the high speed of the locomotive can cause the door to be airproof automatically and the higher the absolute value of the negative pressure, the better the self - airproof effect.
