Study on Rotating Machine Vibration Behaviour using Measured Vibro-acoustic Signals

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Literatures have shown that there is a significant rise in the use of measured vibro-acoustic signals for faults diagnosis in rotating machines. This is particularly based on the premise that affluent information about a rotating machine’s operating conditions is usually conveyed by the sounds of the machine. Several earlier studies have already shown the usefulness and capabilities of amplitude spectra for faults diagnosis. However, very limited analyses of rotating machine’s vibro-acoustic signals are available in literatures. Hence, the current study compares the fused amplitude spectra of measured vibration signals from a flexibly supported rotating machine with different faults, using accelerometers and microphones. The experiments, spectra computations and observations are presented here.
