Acoustic emission analysis for bearing condition monitoring

Acoustic emission analysis for bearing condition monitoring

Acoustic emission (AE) was originally developed for non-destructive testing of static structures, however, over the years its application has been extended to health monitoring of rotating machines and bearings. It offers the advantage of earlier defect detection in comparison to vibration analysis....
