A review of vibration and acoustic measurement methods for the detection of defects in rolling element bearings is presented in this paper. Detection of both localized and distributed categories of defect has been considered. ...

The objective of this paper is to present a systematic analysis of wear particles contained in used lubricant of steam turbinegenerator of a thermal power station. The turbogenerator was condition-monitored over a period ...

The usefulness of acoustic emission (AE) measurements for the detection of defects in roller bearings has been investigated in the present study. Defects were simulated in the roller and inner race of the bearings by the ...
