RELIABILITY AND FATIGUE LIFE PREDICTION OF CYLINDRICAL ROLLER BEARINGS BASED ON FINITE ELEMENTS METHODS

Abstract

This paper presents a case study of the reliability and of the lifetime of cylindrical roller bearings, using experimental information and finite elements methods. The main objective of this paper is to estimate the fatigue life and the reliability parameters of a cylindrical roller bearing subjected to accelerated experiments using the analysis with finite elements. Taking into account the aspects regarding the statistical processing of experimental data, we determined the main reliability parameters, which in turn determine the main characteristics regarding the performance and the warranty period of the cylindrical roller bearings. In this paper, the analysis with finite elements was used to validate and to compare the data resulted from the accelerated reliability tests of the cylindrical roller bearing.
