基于AMESim后登机门液压系统设计与仿真 Introduction Theaircraftboardingdoorisoneofthecrucialequipmentthatanyaircraftmusthaveonboard.Aboardingdoorisamechanismthatallowspassengerstoenterandexittheaircraftwithease.Thehydraulicsystemisoneofthemostcommontypesofsystemsusedintheoperationofaircraftdoors.However,thedesignandsimulationofthehydraulicsystemusedinboardingdoorsareessentialtoensurethesafetyandreliabilityoftheaircraft.ThispaperdiscussesthedesignandsimulationprocessofthehydraulicsystemusedinanaircraftboardingdoorusingAMESim. DesignoftheHydraulicSystem Thehydraulicsystemusedinboardingdoorscomprisesvariouscomponentsthatworktogethertoensurethesmoothoperationofthedoor.Thesecomponentsincludetheactuator,hydraulicpump,hydrauliccylinder,andvalves.Inthisdesign,thehydraulicpumpisresponsibleforsupplyingthehydraulicfluidtothehydrauliccylinder.Thecylinderthenconvertsthehydraulicenergyintomechanicalenergytooperatethedoor. Theactuatorisresponsiblefordrivingthepistonduringtheopeningorclosingofthedoor.Theactuatorismadeofahydraulicmotor,whichisusedtodrivethepump,andapiston,whichmovesthedoor.Thehydrauliccylinderisconnectedtothepiston,anditmovesthedoorbyreciprocatingmotion. Thehydraulicsystemalsocomprisesvarioustypesofvalves,includingthereliefvalve,directionalvalve,andcheckvalve.Thereliefvalveisresponsibleformaintainingthepressureofthehydraulicfluidandpreventingthehydraulicsystemfromoverloading.Thedirectionalvalveensuresthatthehydraulicfluidflowsintherightdirection,whilethecheckvalvepreventsthebackflowofthehydraulicfluid. SimulationoftheHydraulicSystem ThesimulationofthehydraulicsystemusedintheboardingdoorwasconductedusingAMESim.Thesimulationprocessaimedtodeterminetheoptimalhydraulicsystemdesign,evaluatetheperformanceofthesystem,andpredictpossiblefailures. Thesimulationprocessstartedbydefiningthehydraulicsystemrequirementsandspecifications.Next,thehydraulicsystemcomponentsweremodeledusingAMESimsoftware.Thesystemparameters,includingpressure,flowrate,andtemperature,weredefinedbasedonthedesignrequirements
