Abstract

Acoustic Emission (AE) sensors were used to detect signals arising from a cylindrical roller bearing with artificial defects seeded onto the outer raceway. High frequency analysis indicated the condition of the bearings through the determination of an increase in the structural resonances of the system as the size of an artificial defect was increased. As higher loads were applied, frequencies around 100kHz were excited, indicating the release of AE possibly attributed to friction and the plastic deformation as peaks, induced through engraving of the raceway, were over-rolled and worn down. Sensitivity of AE to this level in bearings indicates that detection of subsurface cracking may be possible in future work, providing early indication of incipient failure.
