COMPUTATIONAL ANALYSIS OF WEAR BEHAVIOUR ON PIN ON DISC SETUP FOR THERMAL SPRAY OF COATING USING ANSYS

Abstract

Tribological simulation can be seen as a new study problem developed from modern information technology and computer simulation technology in combination with a variety of mathematical methods in the field of tribology. Due to the complexity of actual tribological systems and different working conditions, the results obtained from traditional simulation test method were often qualitative only, and couldn't be used in designing of tribological systems and practical engineering applications. There is a need to seek new ways and means of in-depth study of the wear quantitative law, otherwise the fundamental breakthrough of the prevention and control of the wear could not be achieved. The tribological simulation research of the typical pin on disc sliding wear test system was carried by the adoption of computer technology and mathematical analysis methods in order to provide a new wear analysis method for the simulation of the basic tribological contact problems. In this research work, the wear simulation model including multiple parameters was established based on experimental data and theoretical data. The parameters of the model were determined by the test data. The simulation model reflects the basic relationship between input and output of the pin on disc dry sliding wear test. Simulation results shows that as the load on pin increase depth wear also increase with angular velocity remains the same .And it also reveals the effect of pin diameter on wear depth.
