摘要:

根据实际地铁线路建立数值模型,分析了过站运行条件下出入口卷帘门的压力变化及卷帘门脱轨的原因,给出了不同行车速度、行车间隔、站台门型式、卷帘门型式、活塞风井开启数量等条件下的卷帘门压力变化特性及特殊运行条件下减小卷帘门承压的措施。

Abstract:

According to the actual underground railway line, establishes the numerical model to analyse the pressure changes of the entrance and exit rolling shutter doors and the reasons for the derailment of the rolling shutter doors under the operating conditions of passing stations. Gives the pressure change characteristics of the rolling shutter doors under different conditions such as different driving speeds, driving intervals, platform door types, rolling door types and the number of open piston air shafts, and the measures to reduce the pressure of rolling shutter doors under special operating conditions.
