摘　　要：利用气体动力学理论建立了地铁列车在应急排烟模式下的瞬变压力数值分析模型。根据深圳地铁公司提供的列车应急排烟方案,利用Fluent软件模拟了列车在该应急排烟模式下列车内外压力变化,3 s时间段内,列车内外瞬变压力峰值为586 Pa/(3 s)。以某地铁“世界之窗-赤湾”2号线作为测试主体进行了实车试验,与理论结果进行比较,两者数据差别较小。计算与测试结果表明,应急排烟模式下列车内的瞬变压力低于德国、UIC、ERRI等国外高速铁路耳膜舒适度准则,也说明该数值分析方法具有较高精度。The research objective of this paper is to study the transient pressure of the emergency exhaust mode by numerical simulation and experiment when the subway train is running.The numerical models of transient pressure were established based on the gas dynamic theory.According to the data of the emergency exhaust scheme provided by Shenzhen Metro Co.,Ltd.,the pressure variation inside and outside the running subway train was analyzed by the software Fluent.The results show that the maximum transient pressure is 586 Pa/(3 s).Furthermore,some experiments have been done in the Window of the world and the Chiwan Line of Metro for verifying the accuracy of numerical approach based on the emergency exhaust mode.The results from both the numerical and experimental analysis are consistent,so that the transient pressure of the emergency exhaust scheme is accord with national technology standard of Germany and other countries,the passenger comfortable standard can nor been lowered and the numerical analysis mode is reliable and of high accuracy.
