摘　　要：在环氧树脂(EP)中加入一定量的r-GO和不同比例的TiO_(2),研究其对EP材料摩擦磨损性能的影响,并基于滑动轴承接触理论,利用ABAQUS有限元软件对添加r-GO/TiO_(2)/EP自润滑层的滑动轴承进行仿真分析,结果表明,加入r-GO或r-GO/TiO_(2)能显著改善EP材料的摩擦学性能,TiO_(2)质量分数为30%的r-GO/TiO_(2)/EP复合材料的摩擦磨损性能最佳;r-GO/TiO_(2)/EP自润滑层的引入能改善轴承的应力和应变分布。The effects of adding a certain amount of r-GO and different proportions of TiO_(2) 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/TiO_(2)/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/TiO_(2) can significantly improve the tribological properties of EP materials,and the r-GO/TiO_(2)/EP composites with 30%TiO_(2) content have the best friction and wear properties;the introduction of r-GO/TiO_(2)/EP self-lubricating layer can improve the stress and strain distribution of the bearings.
