| 目的 研究具有仿生硅藻结构的复合型织构对滑动轴承润滑性能的影响。方法 采用流固耦合的方法，对具有复合型织构的单元模型进行研究，依照硅藻的多孔结构，设计出矩形-半球型、矩形-椭球型、圆柱-半球型及圆柱-椭球型等4种类型的织构，建立这几种复合型织构的单个单元模型。在不同面积率和织构深度条件下，分析不同织构类型对滑动表面摩擦润滑性能的影响。结果 在考虑摩擦性能与承载力的条件下，矩形-半球型和矩形-椭球型织构的最佳面积率为25%，最佳深度分别为0.9 mm和1.1 mm;圆柱-半球型和圆柱-椭球型织构的最佳面积率分别为35%和25%，最佳织构深度分别为1.1 mm和0.9 mm。在不同织构深度条件下，随着复合织构面积率的变化，圆柱-半球型的承载力和摩擦学性能最好，圆柱-椭球型次之，而矩形-半球型和矩形-椭球型复合织构的承载力和摩擦学性能的变化几乎相同。结论 复合型织构的最佳面积率和最佳深度与织构形状有关，在相同面积率和深度的条件下，最佳的复合型织构形状为圆柱-半球型织构。 |

| 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. |
