Application of acoustic emission method to determine the state of friction process of metal collaborating pairs-preliminary results

摘要

In this paper the authors present the definition of the acoustic Emission and examples of preliminary measurements results of friction process registered with the use of model metal collaborating pair, with and without lubricant. The purpose of the presentation is to point out the sources of the AE signal and the correlation between the AE signal parameters and the parameters of friction process. The details of the used methods of the AE signal parameters evaluation are also described.
