Original Abstract

Rolling element bearings are widely-used machine components and their failure can result in damage to the whole machine. A bearing failure can be caused by many factors. In most cases it is damage on the raceway surface as a result of rolling contact fatigue (RCF). This article describes the fatigue analysis consists of determining service-life of a roller bearing using a stress-strain analysis with finite element method and subsequent numeric calculation using software fe-safe with application of multiaxial fatigue criterion. These theoretical results are compared to the experiments carried out on AXMAT test-rig with more accurate defect detection using acoustic emission method. Numerical service-life calculation can be applied as tool for fatigue life prediction of full scale bearing with sufficient correlation with experimental results.

Valivá ložiska jsou široce využívané strojní komponenty a jejich selhání může vést k poškození celého stroje. Toto selhání může být způsobeno mnoha faktory. Ve většině případů je to poškození povrchu oběžné dráhy v důsledku vzniku kontaktní únavy (RCF). Tento článek popisuje únavové analýzy je tvořen stanovení životnosti ložiska analýza namáhání pomocí metody konečných prvků a následné číselný výpočet pomocí softwaru fe-safe s uplatňování kritéria víceosé únavy. Tyto teoretické výsledky jsou porovnávány na základě pokusů provedených na zkušebním zařízení, AXMAT s přesnější detekce vadných metodou akustické emise. Numerický výpočet životnosti lze použít jako nástroj pro předpověď únava života plného rozsahu stupnice s dostatečnou korelace s experimentální výsledky.
