A model of friction for a pin-on-disc configuration with imposed pin rotation

Abstract

A friction model is developed by considering the Coulomb friction model, a probabilistic approach of wear prediction, the kinematics of the pin-on-disc configuration and the elastic theory of bending. The model estimates the magnitude and direction of the frictional force, the pin torque, the probability of asperity contact and the real area of contact distinguishing between the part due to elastic and plastic asperity contacts respectively. Therefore, the proposed model is suitable for the prediction of adhesive wear. It can be applied to metal contacts for conductance characterisation through the plastically deformed asperities which is of great interest for electrical contact resistance studies.

An Essential Studies on Tribology’s: A Short Review

“…A way to decrease unwanted impact of friction by setting an ointment (lubricant), for example, oil, grease or water, in between reaching surfaces is discovered for quite a long time. If the lubricant between the two interfacing surfaces is unlikely, it enables a considerable decrease of the friction coefficient and the friction force [6][7][8][9]. Dr. Robert H. Thurston at the Stevens Institute of Technology (USA) has conducted few studies on the association between friction and lubricant in the early 1870s and followed by Professor Adolf Martens in the year 1885 [10].…”
