Numerično simuliranje premočrtnih stičnih problemov z elastohidrodinamičnim mazanjem = Numerical simulation of elastohydrodynamic lubricated line contact problemsFajdiga, Gorazd ; Glodež, Srečko ; Flašker, Jožeǂ Vǂprispevku je prikazan vpliv elastohidrodinamičnega (EDH) mazanja na napetostno polje v dotikalnem področju mehanskih elementov pri kotalnem in drsnem gibanju. Raziskava obravnava premočrtne ... dotike, ki jih pogosto srečujemo pri dotikalnih elementih, npr.: zobniki, valjčni ležaji, kolesa itn.V prispevku uporabljene računske analize so zasnovane na nadomestnem modelu dveh valjev, ki imata enak polmer, kakor sta krivinska radija dotikalnih mehanskih elementov na mestu realnega dotika. Nadomestna valja sta obremenjena z normalno in tangencialno silo, ki ju poprej določimo s Hertzovo kontaktno teorijo. Pogoji EHD mazanja so upoštevani posredno prek dodatnih zunanjih obremenitev. Za določitev napetostnega polja za različne pogoje mazanja v dotikalnem področju je pri numeričnih analizah uporabljena metoda končnih elementov. Na temelju rezultatov tovrstnih izračunov lahko popišemo vpliv tipičnih veličin mazanja (viskoznost maziva, srednja hitrost stičnih površin) na napetostno polje v dotikalnem področju.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Letn. 44, št. 9/10, sep.-okt. 1998, str. 285-296)Type of material - article, component partPublish date - 1998Language - slovenian, englishCOBISS.SI-ID - 2862619
