DesignandManufacturingofHydrogenPressureVessel

Abstract

Inthiswork,throughfiniteelementstructuralanalysis,singlecarbonstresstest,filamentwindingprocess,andhydraulicbursttest,stablequalityandperformancearesimultaneouslyassuredintheconstructionofhydrogenpressurevessels. Thepricecompetitivenessofthehydrogenpressurevessel,whichisoneofthekeycomponentsofhydrogen-electriccars,isvital.Inthehydrogenenergyindustry,thispaperofferstheresearchcontentstoensurecostcompetitivenessthroughcorrectdesignandtestingforhydrogenpressurevessels. Thefilamentwindingmethodisacompositemoldingtechniquethatinvolveswrappingacontinuousfiberimpregnatedwithresinaroundacylindricalrotatingmandreltocreatearotationallysymmetricstructure.Thehydrogenpressurevesselisconstructedusingthefilamentwindingmethod. Thesinglefibertensiontestwasusedinthisstudytoinvestigatethecompositelayer'sfailurebehavior.Thefibertensiontestresultswereusedtodevelopandanalyzethehydrogenpressurevessel.Acomparisonofthestructuralanalysisvalueandexperimentaldatafromthebursttestwasusedtodeterminethedesign'sreliability.TheoutcomeoftheFiniteElementAnalysis(FEA)wasverysimilartotheresultofthebursttest,withtheresultsmeetingthestandardcertificationcriteria. |본연구에서는유한요소구조해석,단일카본탄소섬유인장시험,필라멘트와인딩,수압파열시험을통해수소압력용기의안정적인품질과성능을동시에확보하였다.현재압력용기생산의가장큰걸림돌은수소탱크생산비절감이다.생산비용분석에서탄소섬유비용은700bar복합압력(COPV)시스템비용을지배한다.본논문은수소에너지산업에서수소압력용기의최적설계와시험을통해원가경쟁력을확보할수있는연구내용을제공한다.단일카본섬유인장시험은복합재료적층의파괴거동을조사하기위해이연구에서사용되었다.단일카본섬유인장시험결과는수소압력용기를개발하고해석하는데사용되었다.구조해석값과버스트시험의실험데이터를비교하여설계의신뢰성을판단하였다.유한요소구조해석의결과는파열시험의결과와매우유사했으며결과는표준인증기준을충족하였다.
