基于RecurDyn的城轨微动塞拉门系统动力学仿真 Title:DynamicSimulationofaMicro-MovingPlatformSlidingDoorSystemBasedonRecurDyn Abstract: Thegrowingrelianceonurbanrailtransportationdemandsefficientandreliableslidingdoorsystemsforpassengersafetyandcomfort.Thispaperpresentsadynamicsimulationofamicro-movingplatformslidingdoorsystemusingRecurDyn,apowerfulmulti-bodydynamicssimulationsoftware.Thestudyaimstoanalyzetheeffectivenessandperformanceoftheproposedsystemunderdifferentoperatingconditions,ultimatelycontributingtothedesignandoptimizationofsuchsystemsinthefieldofurbanrailtransportation. Introduction: Urbanrailtransportationsystemsplayavitalroleinfacilitatingthemovementofmillionsofpeopleinmajorcitiesworldwide.Thesafetyandcomfortofpassengersareofparamountimportance,necessitatingthedevelopmentofinnovativeslidingdoorsystemsforrailwayvehicles.Themicro-movingplatformslidingdoorsystemproposedinthispaperaimstoenhancetheeaseofpassengerboardingandalightingwhileensuringhighlevelsofsafety. Methodology: RecurDyn,acomprehensivemulti-bodydynamicssoftware,isusedtosimulatethedynamicbehavioroftheproposedslidingdoorsystem.Thesoftwareallowsforprecisemodelingandanalysisofthemechanicalcomponentsandtheirinteractions.Thesimulationtakesintoaccountthevariousfactorsthatinfluencethesystem'sperformance,suchasexternalforces,doormass,frictionalforces,andcontactinteractions.Realisticconstraintsandboundaryconditionsareconsideredtoaccuratelyreplicatethesystem'sbehaviorinreal-worldscenarios. Results: Thedynamicsimulationprovidesvaluableinsightsintotheperformanceofthemicro-movingplatformslidingdoorsystem.Theresultshighlighttheinterplaybetweenthedifferentcomponentsandtheireffectsonthesystem'sbehavior.Parameterssuchasdooropeningandclosingspeeds,acceleration,andpositiontrackingareanalyzedunderdifferentloadingconditions.Thesimulationalsohelpsidentifypotentialissues,suchasexcessivewear,failure,ormisalignmentofcomponents,allowingforproactivemeasurestobetakentopreventtheseissuesduringthedesignphase.
