摘要:
运用FDS 软件建立高速列车火灾模型,设置4 种工况分析热释放速率及温度的变化,探究火源所在车厢位置对列车内火势发展的影响。结果表明:起火车厢位于列车前列时,车厢内发生的轰燃现象作用范围大、破坏力强,救援困难;随着起火车厢位置的后移,车内气流抑制轰燃现象的发生并有效稀释车厢内的可燃气体及热量,人员逃生可能性增大。
关键词: 列车内部火灾, 起火车厢位置, 温度, FDS
Abstract: FDS software was used to establish the fire model of high- speed train, the changes of heat release rate and temperature were analyzed under 4 scenarios, and the influence of the location of the fire source on the development of fire in the train was researched. The results showed that when the fire compartment is located in the front of the train, flash-over phenomenon in the compartment has a large scope of action and strong destructive force, the rescue is difficult. As the position of the burning carriage moves back, the air flow inside the carriage inhibits flash- over and dilutes the flammable gas and heat effectively in the carriage, thus increasing the possibility of escape.
