|Title:||Experimental Investigation of Misalignment and Looseness in Rotor Bearing System using Bartlett Power Spectral Density|
|Keywords:||Bartlett Power Spectral Density;Rotor Bearing System;Vibration Signal Processing;Looseness;Misalignment|
|Abstract:||This paper explains Bartlett Power Spectral Density (BPSD) based analysis to identify the faults in a rotor system from spectral density of vibration signal. Misaligned rotor increases vibration and generates abnormal forces at the coupling and transmitted the bearing. In this study, the dynamic response of a rotor bearing system with angular misalignment and looseness are investigated using the BPSD approach. The fault signals are then compared with baseline vibration signals. Angular misalignment was diagnosed from axial vibration and looseness from sub-harmonics signals at 1X, 1-1/2X, 2X, 2-1/2X, 3X.|
