Napoved preboja vode skozi PTFE membrano pri testu vodnega stolpca : magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo

Lenaršič, Rok

V magistrskem delu raziskujemo korelacijo med testi preboja vode in testi vodnega stolpca na PTFE-membranah za ventilacijske enote v električnih vozilih. Opravili smo teste preboja vode in teste ... vodnega stolpca na membranah različnih premerov, ki so bile pritrjene na aluminijaste ploščice, simulirajoč proizvodne pogoje. Za potrebe kalibracije materialnih modelov smo izvedli enoosne natezne preizkuse na pravokotnih vzorcih membrane pri različnih hitrostih deformacij in pri konstantnih napetostih. Na podlagi eksperimentalno določenih tlakov in višin deformacij membrane na točki preboja vode skozi membrano smo s pomočjo numerično določenih lokalnih deformacij razvili model, ki omogoča napovedovanje tlaka, ob katerem pride do preboja vode skozi poro membrane glede na lokalno deformacijo. Model omogoča določitev tlaka testa preboja vode, pri katerem je možnost preboja vode enaka kot pri testu vodnega stolpca pri določenem tlaku in času testa, kar bistveno izboljša možnost nadzora kakovosti in varnost ventilacijskih enot v električnih vozilih.
