| Abstract: |
| In order to study the effect of compound texture with bionic diatom structure on lubrication performance of sliding bearing. In this paper, the fluid-structure coupling method was used to study the cell models with compound textures. According to the porous structure of diatom, four types of textures were designed, which were rectangular-spherical, rectangular-ellipsoid, cylindrical-spherical and cylindrical-ellipsoid respectively. The single cell models of these compound textures were established. The influences of the different texture types of sliding surfaces on the friction and lubrication properties of the sliding surfaces were analyzed under the conditions of different area ratio and texture depth. The results show that under the condition of considering the friction performance and bearing capacity, the optimal area ratio of the rectangular-spherical texture and the rectangle-ellipsoid texture are 25% and the optimal depth of the rectangular-spherical texture and the rectangle-ellipsoid texture are 0.9 mm and 1.1 mm respectively. The optimal area ratio of the cylindrical- spherical texture and the cylindrical-ellipsoid texture are 35% and 25%, respectively, the optimal depth of the cylindrical- spherical texture and the cylindrical-ellipsoid texture are 1.1 mm and 0.9 mm, respectively. In the condition of different texture depth, with the change of area ratio of the compound texture, the cylindrical-spherical compound texture has the best bearing capacity and tribological properties, the cylindrical-ellipsoid compound texture is the next, while the rectangular-spherical and rectangular-ellipsoid compound texture have almost the same changes in bearing capacity and tribological properties. The optimal area rate and depth of the compound texture are related to the texture shape. Under the same area rate and depth condition, the optimal compound texture shape is cylindrical-spherical texture. |
