Calculation of the Archard's wear coefficient of the polymer-based composite sliding bearings

Abstract

Prediction and calculation of wear of the mechanical components in contact is one of the most important tasks in modern engineering. Due to time consumptive experiments and quite expensive test rig, it became even more challenging to evaluate wear by means of the computer simulation instead of the real experiments. With rapid improvement of the computer resources, this task became more realistic, and the results are more concurrent to those obtained by experiments. Since the most of the solvers evaluate wear by means of the Archard's equation, to perform the simulation it is mandatory to determine Archard's coefficient K. This paper provides necessary steps, experimental investigations and measurements in order to calculate Archard's coefficient K, as an input value for the simulation of wear of the polymer-based composite sleeve bearings.
