地铁列车活塞风压导致的站台屏蔽门开关故障分析及改进措施
|
摘要
基于地铁列车活塞风压对地铁车站站台屏蔽门开关的影响,通过分析和计算站台屏蔽门门体所需的最大推力,对行车间隔加密后因列车活塞风压增大导致站台屏蔽门开关发生故障的现象进行故障分析,提出了故障处理方案。该方案在西安地铁2号线实施后,站台屏蔽门故障下降了48.6%。
In line with the impact of train piston wind pressure on the PSD,the maximum thrust needed for PSD is analyzed and computed. After repeated transit interval encryption,the actual train piston wind pressure increases obviously,resulting in the switch fault of metro PSD. Through analysis of the operation faults,proper processing schemes are proposed,which have been applied to Xi'an metro Line 2 and the failure of PSD has fallen by 48. 6%.
