2023年市域列车车内空气压力波动控制技术于晓良王胜光(中车青岛四方机车车辆股份有限公司，266111，青岛∥第一作者，高级工程师)摘要针对市域列车运行速度较高且运行线路隧道阻塞比较大的特点，为有效抑制车外急剧变化的空气压力波动传入车内，在简述车内空气压力波动控制指标及高速动车组空气压力波动控制方式的基础上，提出了市域列车整车气密性控制指标，介绍了市域列车两种被动式压力保护系统的组成、工作原理及控制方式。现车测试结果表明，采用两种控制方案，车内空气压力波动均满足3s内最大空气压力变化不大于800Pa的要求，控制效果良好。此外，还对新风电动风量调节阀全开和全关状态下的车内空气压力波动进行了测试。测试结果表明，新风电动调节阀全关状态下的车内最大空气压力3s内变化值可降低约10%。关键词市域列车;空气压力波动;被动式压力保护系统中图分类号U239．5;U270．38+3DOI:10．16037/j．1007－869x．2023．01．044CityＲailwayTrainInteriorAirPressureFluctuationControlTechnologyYUXiaoliang，WANGShengguangAbstractInviewofthecharacteristicsofhightrainrunningspeedandhighoperatinglinetunnelblockingratioofcityrail-way，inordertoeffectivelypreventtheexternalairpressurefluctuationthatchangesdrasticallyfromenteringtrain，basedonthebriefdescriptionoftheinteriorairpressurefluctuationcontrolindexandtheairpressurefluctuationcontrolmodeofhigh-speedEMU，theoverallair-tightnesscontrolindexofcityrailwaytrainisproposed．Thecomposition，workingprincipleandcontrolmodeoftwokindsofpassivepressureprotectionsystemsforcityrailwaytrainarestudied．In-vehicletestresultsshowthatboththeinteriorairpressurefluctuationcontrolschemescanmeettherequirementofmaximumairpressurechangeoflessthan800Pawithin3seconds，andthecontroleffectisgood．Inaddition，theinteriorairpressurefluctuationistestedunderboththefullyopenandfullyclosedstatesoffreshairelectricvolumeregulatingvalve．Testresultsshowthatthemaximumpressurechangewithin3secondscanbereducedby10%underthefullyclosedstateoffreshairelectricregula-tingvalve．Keywordscityrailwaytrain;airpressurefluctuation;passivepressureprotectionsystemAuthor'saddressCＲＲCQingdaoSifangCo．，Ltd．，266111，Qingdao，China...
