Pressure analysis of rolling shutter doors at underground railway station entrance and exit under passing station operation conditions

Ma Jiangyan, Deng Baoshun, Liao Kai and Niu Yongsheng


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.
