A Numerical Simulation for the Sliding Surface Temperature of Polyoxymethylene

Abstract

An unsteady numerical simulation was carried out to evaluate the sliding surface temperature of polyoxymethylene (POM) for wear test. The numerical model consists of two-dimensional hollow circular cylindrical POM, metallic shaft, and ambient air. The effect of conductive and convective heat transfer on the sliding surface temperature was investigated. Simulation results are in a good agreement with experiments. The influence of sliding conditions on the sliding surface temperature and limiting PV value was also discussed. Moreover, ON-OFF operation was performed in order to consider actual sliding conditions.
