Abstract
Acoustic Emission (AE) has been long established as a sensitive tool for detecting damage and failure in engi-neering structures, where sensors are used to detect the elastic stress waves originating from crack growth, impact damage, plastic deformation and other failure mechanisms. It is a useful tool capable of detecting failure at an earlier stage than more conventional moni-toring techniques, and offers much potential insight into conditions in tribological contacts. This paper examines the sensitivity of AE to mixed lubrication conditions, with a view to evaluating the suitability of the technique for monitoring heavily load-ed concentrated contacts in power transmission gear systems where roughness scale fatigue phenomena such as micropitting are a problem. It then discusses the results of using AE to monitor bearings, highlighting some of the challenges which must be overcome to enable its adoption as a condition monitoring tool.
