Description

This dataset concerns the generation of acoustic emission by surfaces in lubricated contact under mixed lubrication conditions where there is a lubricant film present, but where there is also significant interaction of asperities on the contacting surfaces.  The research investigated the correlation between contact conditions (via consideration of the lambda ratio) and the generation of AE in experiments conducted using twin disc machines, and additionally in real components using a rolling-element bearing test rig.  Furthermore, data on surface modification during the running-in process and micropitting failure were recorded during the disc machine testing, together with electrical contact resistance measurements to indicate the level of metallic contact.  The dataset consists of three groups of files - these are (1) the electrical contact resistance and running-in data files, stored as text files (2) the raw wavestream files from the disk machine tests (stored in plain text format) and (3) the parametric AE and raw wavestream data from disk machine tests, also in text file format.
