  • Simuliranje širjenja površinske utrujenostne razpoke na zobeh zobnikov
    Glodež, Srečko
    The paper describes a computational model for the simulation of surface fatigue crack growth in the contact area of gear teeth flanks. The computational analysis is performed using the real model of ... gear teeth flanks that are subjected to normal loading (Hertzian contact pressure), tangential loading (friction between gear teeth flanks) and additional external contact forces that arise from the EHD-lubication conditions. The j-integral method in the framework of the finite element analysis is then used for simulation of the fatigue crack propagation from the initial to the critical crack length, when the surface material layer breaks away and pit appears on the surface. The computational results show that the model reliability simulates the surface fatigue crack growth under contact loading and can be used for computational predictions of surface pitting for various contacting mechanical elements like gears, bearings, wheels, etc.
