Continuous and proper oil lubrication between the friction pair can reduce wear and increase service life of mechanical components. In this paper, the friction experiment and finite element analysis method are combined to study the tribological properties and oil retention mechanism of sinusoidal textured under various width-depth ratios and oil supply. The results indicate that the sinusoidal texture can improve tribological property. ST-3 (the width-to-depth ratio is 1.35) has optimal oil retention property. Compared with untextured specimens (UT), the wear and friction coefficient of ST-3 are reduced by 74% and 7.7%, respectively. Furthermore, the maximum positive pressure is proportional to the non-friction area. This research provides a basis for the optimization design of texture.

摩擦副之间连续且适当的油润滑可以减少磨损并延长机械零件的使用寿命。本文结合摩擦实验和有限元分析方法，研究了在不同宽高比和供油条件下正弦织构的摩擦学性能和保油机理。结果表明正弦纹理可以改善摩擦性能。ST-3（宽深比为1.35）具有最佳的保油性。与无纹理的样品（UT）相比，ST-3的磨损和摩擦系数分别降低了74％和7.7％。此外，最大正压力与非摩擦面积成正比。该研究为纹理优化设计提供了依据。
