【摘要】 本文主要针对屏蔽门系统,对由列车活塞效应引入隧道的新风量进行了模拟分析与计算,找出了进入隧道新风量的主要影响因素,得到了列车阻塞比、列车时速、列车编组、运行对数、活塞风道设置位置等多种不同工况组合下的新风量计算结果,在轨道排风系统运行时,新风量为轨道排风量与列车活塞效应引入新风量之和,随后针对车站进出站端设单活塞风道时隧道新风量进行了详细分析,结果表明出站端设单活塞要优于进站端设单活塞。 【Abstract】 focus on the platform screen doors system,the piston effect of fresh air caused by train is simulated and analyzed,the impact factors of fresh air are determined,the fresh air volume in different train blockage ratio,train velocity,train couples and position of piston duct are gained.Results show that fresh air volume is the sum of exhaust air volume and induced fresh air volume caused by piston effect when the railway track exhaust system operates;single piston fixed in exit is better than fixed in entrance. 【关键词】 屏蔽门系统; 单活塞; 双活塞; 新风量 【Key words】 platform screen doors system; single piston; double piston; fresh air volume
