Numerical Fretting© Wear Simulation of Deep Groove Ball Bearing Under Radial Variable Load

Abstract

Bearing has become one of the most widely used mechanical components over the world. Even this component has been extensively studied, there exist especial applications or untypical operating conditions that still must be studied. This work accomplished a numerical wear simulation based on a finite element model of a deep groove ball bearing under radial variable load. This analysis considers a reduced symmetry model and the implementation of the friction energy model as wear damage indicator. This allows to simulate the effect of different bearing parameters, such as, ball-raceway conformity factor and friction coefficient. Results allow to understand the effect of different bearing parameters and concludes how to reduce this fretting wear damage.
