Modeling Nonlinear Heat Transfer for a Pin-on-Disc Sliding System

Abstract

The objective of this research is to develop a numerical method to characterize heat transfer and wear rates for samples of Vascomax 300 or Maraging 300, steel. A pin-on-disc experiment was conducted in which samples were exposed to a high-pressure, high speed, sliding contact environment. This sliding contact generates frictional heating that influences the temperature distribution and wear characteristics of the test samples. A two-dimensional nonlinear heat transfer equation is discretized and solved via a second-order explicit finite difference scheme to predict the transient temperature distribution of the pin. This schematic is used to predict the removal of material from the specimens over time based on the temperature profile of the pin.
