Modeling and simulation of wear in a pin on disc tribometer

Abstract

A very efficient, incremental implementation of Archard's wear model on the global scale for pin wear and disc wear in a pin-ondisc tribometer is presented. The results from the model are in good agreement with experimental results. The identified wear model is implemented in a finite element based tool (Wear-Processor) for 3D wear simulations and the results compare favorably with that from the global wear modeling scheme.

Identification of a friction model for the bearing channel of hot aluminium extrusion dies by using ball-on-disc tests

“…In the meanwhile, the selection of ball size and sliding distance is of great importance. In general, the contact pressure decreases with increasing ball size [25] and increasing sliding distance [26].…”

“…During the tests, high contact pressure and intensive surface enlargement can be achieved [9,10,12,26,27]. Most recent research results have shown that different contact conditions in the extrusion friction tests can be achieved by adjusting the extrusion ratio [27]: low contact pressure and surface enlargement can be achieved when low extrusion ratio is used, thus a high friction sensitivity can be obtained.…”
