Abstract
The article discusses the application of information entropy to the quantitative assessment of abrasive particle distribution in the friction zone. Using discrete element modelling (DEM) and in-situ experiments, the interaction modes between sand particles moving between the surface of a rubber roller and a flat steel surface inclined at different angles were investigated. Shannon entropy was calculated based on visual analysis of the distribution of active particles in the friction zone and compared with the amount of abrasive wear. A stable correlation was found between the uniformity of distribution and the wear rate. It was demonstrated that as entropy increases, the system tends towards a steady state with a limit entropy value of H∞ ≈ 3.4. The method showed high sensitivity and suitability for assessing and predicting wear in tribological systems.
期刊介绍:
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
