Vibrational Analysis of Self Align Ball Bearing Having a Local defect through FEA and its Validation through Experiment

The rolling bearings dynamical behaviour analysis is a important condition to determine the machine vibration response. The rolling bearing, with outer ring fixed, is a multi body mechanical system with rolling elements that transmit motion and load from the inner raceway to the outer raceway.Modern trend of Dynamic analysis is useful in early prediction; simulation of rotor bearing system as manufacturing of prototype is time consuming, costly, and required further analysis for fatigue failure. Dynamic analysis has become a very powerful tool for the betterment of the actual performance of the system. The methodology for prediction and validation of dynamic characteristics of bearing rotor system vibration is studied. PRO-E® and ANSYS software are the promising tools for the modeling and modal analysis of the bearing rotor system. Experiment result has been taken for the analysis of the signal that has been obtained through the use of FFT analyser. Matlab® program is generated for finding the BPFO and BPFI for bearing system; its graphical values are shown. The goal of this study is to prevent the system from the breakdown by continuous monitoring of vibration values.
