BALL BEARING ANALYSIS OF FAULT SIMULATION USING FINITE ELEMENT METHOD-A REVIEW
Keywords:
Effectiveness, emanating,, outer-race, validate.Abstract
Effectiveness of transient analysis of the finite dement bearing model to simulate the vibration signal emanating from ball bearing with faults is presented in this work. It is difficult to identify the ball bearing defect either in frequency spectrum or time domain when the defect is at incipient stage. Further, it is difficultto experimentally obtain vibration signals from bearing having fault at incipient stage. Thus, need for accurate simulation of ball bearing fault at incipient stage is considered essential. A Computer Aided Design (CAD) model of a ball bearing having a minor crack in outer-race was created using commercially available software. It was shown that identification of ball bearing defect in frequency spectrum is difficult. The results were validated with experimental results.
