地铁屏蔽门气密性检测方法研究
Research on detection method for air tightness of platform screen door in underground railway
摘要：
地铁屏蔽门系统因其经济性和安全性在我国得到了广泛的应用，但各个车站屏蔽门的气密性差异较大，而屏蔽门的气密性又对车站的出入口渗风量有巨大影响。提出了一种屏蔽门气密性检测方法，定义当量缝隙宽度来衡量屏蔽门气密性，并对2个车站进行了气密性检测，验证其方法的可行性。

Abstract：
Platform screen door in underground railway is widely used in China because of its economy and security. But there is a great difference in the air tightness of platform screen doors, which significantly influences the air infiltration in the entrance of the stations. Puts forward a method to detect the air tightness of platform screen door and defines an equivalent gap width to evaluate the air tightness. Also tests the air tightness of platform screen doors in two stations and verifies the feasibility of the method.
