Vibroakustična karakterizacija krogličnih ležajev s povečano zračnostjo : magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo

Bregar, Tomaž, 1993-

V tem delu je predstavljen razvoj numeričnega modela, ki omogoča simulacijo hrupa zaradi udarjanja kotalnih elementov z obroči ležaja. Obravnavani so kroglični ležaji s povečano zračnostjo, katerih ... kotalni elementi so kroglice. Dinamika obravnavanega ležaja je izračunana s poenostavljenim analitičnim modelom, ki nadomešča ležaj preko zapisa togostne matrike. Učinkovito simulacijo dinamike sistema dosežemo z uporabo modalne redukcije, s katero znižamo število prostostnih stopenj modela. Potek zvočnega tlaka ob trku kroglice je simuliran z metodo končnih elementov in validiran s preprostim eksperimentom. Izdelano je tudi preizkuševališče, s katerim smo ponazorili udarjanja kotalnih elementov v obroč ležaja. Preizkuševališče nam omogoča končno validacijo numeričnega modela zvoka, ki se pojavi ob trku kroglic.
