MODELLING OF WEAR UNDER THE CONDITIONS OF HIGH SLIDING SPEEDS
Journal Title: Tribologia - Year 2018, Vol 280, Issue 4
Abstract
The paper presents a probabilistic model of the wear process of machine elements under the conditions of high-speed friction using the thermo-kinetic theory of fracture. The definition of model parameters is based on the probabilistic-physical approach. The model is presented in a discrete form and adapted for using computer simulation methods that require spatio-temporal sampling of computational models. The analysis of calculation results shows that the dominant factor that affects the stress-strain state, and therefore the wear of the tribological system processes, is the rate of change of the friction coefficient from static to dynamic values. The rate of change in the friction coefficient was proposed as an effectiveness criterion of using methods for increasing the wear resistance of systems under the conditions of high-speed friction.<br/><br/>
