Introduction

Tribology is the study of friction, wear, and lubrication of interacting surfaces in relative motion. It plays a crucial role in the design and performance of mechanical components, such as roller bearings, which are widely used in various industries to support rotating shafts. Roller bearings are critical components in machinery, providing low friction and high load carrying capacity. Understanding the tribological behavior of roller bearings is essential for improving their performance and reliability.

In recent years, Finite Element Method (FEM) has emerged as a powerful tool for analyzing the tribological behavior of mechanical components. FEM allows for the prediction of contact pressure distribution, stress distribution, and temperature distribution in roller bearings under different operating conditions. By using FEM, researchers can optimize the design of roller bearings to reduce wear and increase their lifespan.

This thesis aims to investigate the tribological behavior of a roller bearing using the Finite Element Method. The study will focus on analyzing the contact pressure distribution, stress distribution, and temperature distribution in the roller bearing under various operating conditions. The findings of this research will provide valuable insights into the tribological performance of roller bearings and contribute to the optimization of their design.
