基于固体颗粒介质的板材软模成形工艺(英文) Abstract: Solidparticlemediasheetformingtechnology(SPSMF)isanovelprocesswhichhasdevelopedrecentlyinsheetformingtechnology.InSPSMFprocess,aflexiblemembraneloadedwithacontrollableamountofsolidparticlesisusedasatoolforformingthesheetmaterialintoadesiredshape.ThemainadvantageofSPSMFprocessliesinthefeasibilityofusingdifferenttypesandsizesofparticlesasmedium.ThispaperdescribesthebasicprinciplesandtheoreticalconsiderationsofSPSMFprocessanddiscussesitsapplications,includingvariousmaterialsthatcanbeformedbythisprocess,suchasmetals,ceramics,polymers,etc.Moreover,thepaperpresentsanexperimentalmethodologyfortheapplicationofSPSMFtosheetformingprocess. Introduction: Sheetformingprocesshasbeenplayinganimportantroleinmanufacturingindustries.Theconventionalmethodsofsheetformingincludestamping,deepdrawing,bending,etc.However,thesemethodsarelimitedinusingspecifictypesofmaterial,andthetoolsarecostlytoproduceandmaintain.Inrecentyears,theSolidParticleMediaSheetForming(SPSMF)processhasbeendevelopedtoaddresstheseproblems.SPSMFprocessusessolidparticlesasthemediatoformsheetmaterial,andthetoolsaremadebyaflexiblemembranewhichcanbereusedmanytimes.TheSPSMFprocesshasmanyadvantagesoverconventionalsheetformingmethodsandhasbeenwidelyusedinvariousindustries. Basicprinciplesandtheoreticalconsiderations: TheSPSMFprocessreliesontheabilityofgranularmediatodeformandmove,andthesystemwillbeinaquasi-staticstatewhenthepressureontheparticlesisbalanced.Themedialoadedonthemembranecanbecomposedofdifferenttypesandsizesofparticles,whichcanachievetherequireddeformationdegree.Therefore,theSPSMFprocessisaversatilemethodforformingsheetmaterials.
