2023年基于EN14363:2016(E)的地铁车辆扭曲安全性研究郭振通周鲁宁薛萍(南京中车浦镇城轨车辆责任有限公司,210031,南京∥第一作者,高级工程师)摘要基于EN14363:2016(E)中规定的扭曲安全性试验要求,详细阐述了实验室内无扭曲试验台和有扭曲试验台情况下进行扭曲试验的方法,并建立了扭曲试验台仿真模型。以某出口地铁车辆为例,分析了车辆在空气弹簧有气和失气状态下的轮重变化趋势。研究结果表明,在空气弹簧有气和无气状态下,车辆轮轨垂向力最小值分别为25.53kN和19.65kN,其相应的轮重减载率分别为0.46和0.59,小于0.60的安全限值,均符合标准要求。此外,空气弹簧失气状态下的轮轨垂向力增载和减载量明显大于其有气状态,二系悬挂参数对车辆的抗扭曲性能影响明显。关键词地铁;车辆;扭曲安全性;扭曲试验台中图分类号U270.1+4DOI:10.16037/j.1007-869x.2023.01.016ResearchonMetroVehicleTwistSafetyBasedonStandardEN14363:2016(E)GUOZhentong,ZHOULuning,XUEPingAbstractBasedonthetwistsafetytestrequirementsspecifiedinEN14363:2016(E),thetestmethodsunderconditionswhethertwisttestrigisavailableornotinthelaboratoryaree-laborated,andthesimulationmodeloftwisttestrigisestab-lished.Takinganexportmetrovehicleasexample,thevehiclewheelweightchangetendencyundertheconditionsofairspringinflatedanddeflatedisanalyzed.Researchresultsshowthattheminimumwheel/railverticalforcesofairspringinflatedanddeflatedare25.53kNand19.65kNrespectively,andthecorrespondingwheelweightunloadingratiois0.46and0.59respectively,meetingthestandardrequirementsbelow0.60safetylimit.Inaddition,theincreaseanddecreaseofwheel/railverticalforceundertheconditionofairspringdeflatedissignificantlygreaterthanthatoftheairspringinflated,indica-tingthattheimpactofsecondarysuspensionparameteronvehi-cleanti-twistperformanceisobvious.Keywordsmetro;vehicle;twistsafety;twisttestrigAuthor'saddressCRRCNanjingPuzhenCo.,Ltd.,210031,Nanjing,China随着我国“一带一路”战略的实施,促进了我国与世界其他各国之间的联系,也为我国的轨道交通走出去提供了良好的契机。然而,各国不同的车辆设计标准是车辆出口面临的重要问题。国外认可的标准主要有EN(欧洲标准)、UIC(国际铁路联...
