This paper introduces an analytical approach to optimize the textured bearing with cavitation to improve the load support. For this purpose, a grooved parallel slider bearing is analyzed based on the Reynolds equation and mass conservation equation, adopting the cavitation model used in the inlet suction mechanism. In order to clarify the effect of cavitation, the pressure distributions of the bearing in the three possible cases determined by whether cavitation occurs are analyzed and compared. It is found that the bearing obtains the largest load support in the case that the lowest pressure just reaches the cavitation pressure. Considering this condition, the analytical solutions of the optimal geometric parameters in the bearing with single groove are finally obtained. The results calculated by FLUENT are also consistent with the analytical solutions. The analytical solutions above are extended to the bearing with multiple grooves and reciprocating bearing. The results suggest that the bearing with only one flat wide groove and the bearing with larger textures under slower speed and higher inlet pressure have better load support.

带气穴的带槽平行滑动轴承的分析与优化

本文介绍了一种优化带有气蚀的纹理轴承的分析方法，以改善负载支撑。为此，基于雷诺方程和质量守恒方程，采用进口吸入机构中使用的空化模型，对带槽平行滑动轴承进行了分析。为明确汽蚀的影响，对由是否发生汽蚀决定的三种可能情况下轴承的压力分布进行分析比较。发现在最低压力刚好达到空化压力的情况下，轴承获得最大的载荷支撑。考虑到这种情况，最终得到了单槽轴承中最优几何参数的解析解。FLUENT 计算的结果也与解析解一致。以上解析解推广到多槽轴承和往复轴承。结果表明，只有一个扁平宽槽的轴承和在较低速度和较高入口压力下具有较大纹理的轴承具有更好的负载支撑。
