Simulation and experimental studies on sliding wear of aluminum alloy under dry condition using asymmetric contact models

Abstract

Wear is an undesirable surface interaction phenomenon in which material is removed from the interacting surfaces. Wear deteriorates the life of the component, reduces mechanical properties and leads to material wastage. The pin on disc is the most common test used to characterize the wear. Full scale testing is often required if contact pressure and geometry are kept as variables. Full scale tests are time consuming and expensive too. Wear modeling using Finite elements can provide useful data during the conceptual stage of the design. This work describes the pin on disc experiment on Aluminum alloy (AI7075) with AISI1060 steel disc rotating at 400 RPM with 50 N load. Ansys was used to simulate the accelerated wear model. Both symmetric and asymmetric contact models are considered. The results are compared with actual experimental values and found that the experimental values match with simulation results.
