20.500.12556/DKUM-95911 Termo-mehanska analiza nosilca za valje magistrsko delo Thermo-Mechanical Analysis of the Roll Support V magistrskem delu analiziramo nosilec za valje, ki je skupaj z valji izpostavljen ciklični toplotni obdelavi. Pri tej temperature močno narastejo, kar povzroča pojav lezenja. Mehanizem lezenja, njegovi vplivi ter uporabljene metode analize so sistematično predstavljeni. Na tej podlagi pripravimo numerični model in izvedemo preračune ključnih parametrov prestopa toplote. Sledi termo-mehanska numerična simulacija obravnavane toplotne obdelave. Na podlagi dobljenih rezultatov ocenimo življenjsko dobo nosilca oziroma določimo število ciklov toplotnih obdelav do porušitve. In this master’s thesis, the analysis of a roller support and the rollers exposed to cyclical heat treatment is analysed. During heat treatment, the temperature rises significantly, causing creep to occur. The creep mechanism, its effects and the applied analysis methods are systematically presented. Based on this, a numerical model is developed, and key heat transfer parameters are calculated. A thermo-mechanical numerical simulation of the considered heat treatment process is then performed. Based on the obtained results, the service life of the support is evaluated – in other words the number of heat treatment cycles to failure is determined. lezenje dimenzioniranje na življenjsko dobo numerična simulacija toplotne obdelave prestop toplote creep lifetime dimensioning numerical simulation heat treatment heat transfer true true false [Ž.
