Friction and Wear Properties of Epoxy Resin Self-Lubricating Plain Bearings and Simulation Analysis
The effects of adding a certain amount of r-GO and different proportions of TiO2 to epoxy resin(EP)on friction and wear properties of EP materials are studied.Based on contact theory of plain bearings,the plain bearings with r-GO/TiO2/EP self-lubricating layer are simulated and analyzed by ABAQUS finite element software.The results show that the addition of r-GO or r-GO/TiO2 can significantly improve the tribological properties of EP materials,and the r-GO/TiO2/EP composites with 30%TiO2 content have the best friction and wear properties;the introduction of r-GO/TiO2/EP self-lubricating layer can improve the stress and strain distribution of the bearings.
