Računalniško modeliranje gibanja goriva in njegov vpliv na konstrukcijo rezervoarja = Computational modelling of fuel motion and its interaction with the reservoir structureVesenjak, Matej ...Računalniški modeli vozil za simuliranje trkov vedno natančneje opisujejo obnašanje resničnih vozil. Rezervoar za gorivo je eden izmed elementov vozil, katerega računalniški modeli so bili do sedaj ... zelo poenostavljeni. Takšni modeli upostevajo le vztrajnost mase goriva, ki je z masnimi točkami pritrjenana steno rezervoarja, vendar pa je vpliv gibanja goriva v rezervoarju popolnoma zanemarjen. Prispevek opisuje nove računalniske modele, s katerimi je mogoče simulirati deformacijo rezervoarja za gorivo ob upoštevanju gibanja goriva pri trku vozila. V ta namen so bile vrednotene štiri metode simuliranje gibanja tekočine (Lagrange, Euler, poljubnostna Lagrange-Eulerjeva metoda - PLE in hidrodinamika zglajenih delcev - HZD) v rezervoarju preproste oblike, analizirane z eksplicitnim programom LS-DYNA. Računalniski rezultati so bili primerjani s poprej objavljenimi preizkusnimi opazovanji, pri čemer je bila ugotovljena zelo dobra primerljivost med rezultati. Najprimernejsi metodi (HZD in PLE) sta bili kasneje uporabljeni v dinamičnih simulacijah dejanskega rezervoarja za gorivo. Simulacije so pokazale, da predstavljeni modeli rezervoarja ob upostevanju gibanja goriva zagotavljajo mnogo natančnejše rezultate v primerjavi z znanimi poenostavljenimi modeli.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 52, št. 2, 2006, str. 85-100)Type of material - article, component partPublish date - 2006Language - slovenian, englishCOBISS.SI-ID - 9188123
