| 为研究轴颈表面加工混合排列的微观织构对滑动轴承性能的影响，基于雷诺方程建立无偏心径向滑动轴承动压润滑模型，设计3种单一微观织构与3种混合微观织构，最后采用MATLAB软件编程，分析微观织构形状、面积率等参数对无偏心径向滑动轴承性能的影响。研究结果表明：相比于单一微观织构，[JP2]混合排列织构化无偏心滑动轴承承载力提升程度与混合排列种类有关；存在最优微观织构结构参数和混合织构排列种类，使轴承承载力提升最大。 |

| Based on the Reynolds equation, a finite length non eccentric radial sliding bearing hydrodynamic lubrication model was established. Three different kinds of single surface texture and three different mixed surface texture lubrication model were established. Programming with MATLAB, the performance of load carrying capacity of non eccentric radial sliding bearing with different types and different area density of surface texture were respectively compared and analyzed. The results showed that compared with the single surface texture, the enhancement degree of load carrying capacity of mixed arrangement surface textures would depend on its arrangement type. Furthermore, it has been found that there were optimum parameters and arrangement type of surface texture of non eccentric radial sliding bearing to reach the max maximum of load carrying capacity. |
