MKE - analiza napetostno-deformacijskega stanja na valju pri grobem vročem valjanju = FEM - determination of stress-strain state of rolls at hot roughing mills
Drobne, Matej ; Göncz, Péter ; Glodež, Srečko
Predstavljena je analiza napetostno-deformacijskega stanja na valju pri operaciji grobega vročega valjanja pločevine. Prikaz rezultata napetostno-deformacijskega stanja pri valjanju smo dobili na ...osnovi numerične simulacije s pomočjo programskega paketa Abaqus Standard. Materialne parametre, ki so uporabljeni pri izvedbi simulacije, smo pridobili na osnovi realnih preskusov oziroma iz strokovne literature. V prispevku sta analizirani dve simulaciji valjanja: v prvem primeru ni upoštevan vpliv zaostalih napetosti, v drugem pa smo modelu s pomočjo centrifugalne sile vnesli zaostale tlačne napetosti v plašč valja in s tem vršili nadaljnjo simulacijo valjanja. Rezultate smo medsebojno primerjali in podali predloge za nadaljnje delo na obravnavanem področju.
