Effect of Localized Defect on the Vibration Behavior of Cylindrical Roller Bearing-Rotor System

Abstract

This paper presents a mathematical model to investigate the vibration behavior of a rotor-bearing system due to localized defects of inner race and outer race for cylindrical roller bearing. In the formulation, the contacts between rolling elements and inner/outer races are considered as nonlinear springs as well as nonlinear damping. The governing equations of motion are formulated using energy approach,
