Abstract

There is currently considerable interest in using Acoustic Emission (AE) to measure the contact conditions in the critical components of rotating machinery. Researchers have shown that asperity interaction between their contacting surfaces is a source of AE. However there have been few attempts to describe the change in AE response as the surface changes. The paper presents the AE response from the running-in and subsequent micro-pitting fatigue test of an elastohydrodynamic contact operating in the mixed lubrication regime, between two axially ground disks. The results presented in this paper show that AE is extremely sensitive to modification of surface asperities and has great potential for use in monitoring running-in and wear regimes.
