Effect of Localized Defect on Inner Race of Cylindrical Roller Bearing on Vibration Behavior of Rotor Bearing System

摘要

This paper presents a mathematical model to investigate a nonlinear vibration behavior of a rotor-cylindrical roller bearing system due to localized defects on innerrace. In the formulation, the contact between rolling element and inner race is considered as nonlinear spring. Nonlinear equations are solved by Newton Raphson method for n-unknown nonlinear simultaneous equation using of solve function using programming. Equations of motions are solved by implicit type numerical integration method-New mark β method. Here results are obtained in the form of frequency domain signal plots and phase plot/Poincare maps. The validity of the proposed model verify by comparison of frequency components of the system response with those obtain from experiments.
