Study on Dynamic Friction Process of Sweat Self-Lubricating Composite at Elevated Temperature Based on CA Method

Abstract

In the paper, a three-dimensional model is developed with cellular automaton method based on a series of experiments and the self-lubricating mechanism analysis. The model is used to investigate the dynamic friction process of sweat self-lubricating composite during high temperature sliding. The sliding friction coefficient and the distribution of lubricant on the worn surface of the composite are calculated out by using the cellular automaton (CA) model. The agreement between the computing and experimental results shows the model developed in the paper can be effectively used to study the friction behaviors of the sweat self-lubricating composite at high temperature.
