城市轨道交通翼2023年基于列车-桥架耦合振动模型的高温超导磁浮车辆悬挂参数优化何燕吴吴兴文*杨浚纲法池茂儒？（1.西南交通大学机械工程学院，610031，成都；2.西南交通大学牵引动力国家重点实验室，610031，成都//第一作者，硕士研究生）摘要为提高高温超导磁浮车辆在高速运行下的品质，建立了高温超导磁浮列车-桥梁耦合振动模型，分析了桥梁刚度和车辆悬挂参数匹配对车辆系统动力学性能的影响。并通过叠加轨道不平顺谱实现桥梁预拱，分析车辆系统的动力学响应。结果表明：高温超导磁浮车辆在高速运行下，其平稳性对减振器阻尼和桥梁挠跨比的取值较敏感；桥梁挠跨比取1/7752、桥梁挠度取4.1mm、桥梁预拱量取4mm时能抵消车辆高速运行过程中桥梁下挠带来的线路不平顺，使车辆动力学性能达到最优。关键词高温超导磁浮车辆；悬挂参数；列车-桥梁耦合振动模型中图分类号U270.33:U237D0I:10.16037/j.1007-869x.2023.06.005OptimizationofHigh-temperatureSupercon-ductingMaglevVehicleSuspensionParame-tersBasedonTrain-BridgeCouplingVibra-tionHEYan,WUXingwen,YANGJungang,CHIMao-ruAbstractInordertoimprovethequalityofHTS(high-tem-peraturesuperconducting)maglevvehicleunderhigh-speedop-erationcondition,theHTSmaglevtrain-bridgecouplingvibra-tionmodelisestablished,andtheinfluenceofbridgestiffnessandvehiclesuspensionparametermatchingonvehiclesystemdynamicsperformanceisanalyzed.Bridgepre-camberingisre-alizedthroughsuperimposingspectrumoftrackirregularitiesandvehiclesystemdynamicresponseisanalyzed.Theresultssuggestthatduringthehigh-speedoperationofHTSmaglevve-hicle,thestabilityismoresensitivetothedampingofthevi-brationreductiondeviceandthevalueofbridgedeflection-spanratio;whentheaboveratiois1/7752,bridgedeflectionis4.1*中国科协青年托举工程项目（2019QNRC001）；四川省自然科学基金项目（2022NSFSC0469）**通信作者·24·mmandbridgepre-camberingis4mm,thelineirregularitycausedbybridgedeflectioninvehiclehigh-speedoperationcanbeeliminatedandthevehicledynamicsperformanceisopti-mal.KeywordsHTSmaglevvehicle;suspensionparameter;ve-hicle-bridgecouplingvibrationFirst-author'saddressSchoolofMechanicalEngineer-ing,SouthwestJiaotongUniversity,610031,Chengdu,China0引言在...
