| 摘 要： |
In this study, the distribution of circular concave textures on sectorial thrust bearing pads is optimized for improving load bearing capacity and reducing friction coefficient. Textures in a sector-shaped array are supposed to be existed or empty, labeled as 1 or 0. Then, the texture distribution is optimized according to a Genetic Algorithm. A distribution/coverage in an asymmetric triangular/trapezoid shape at the inlet of sectorial bearing pad is obtained as the optimized texture arrangement. Effects of convergent ratio and width are studied as well, which demonstrate for bearings with small convergent ratio and width, the tribological improvement effect is more significant.
在本研究中，针对扇形推力轴承垫片上的圆形凹面纹理分布进行了优化，以提高承载能力并降低摩擦系数。扇形阵列中的纹理可设为存在或不存在，分别标记为1或0。随后，采用遗传算法对纹理分布进行优化，最终得到一种呈非对称三角形/梯形的分布/覆盖结构，作为优化后的纹理排列方案。同时，还研究了收敛比和宽度的影响，结果表明，对于收敛比和宽度较小的轴承，其摩擦学性能改善效果更为显著。 |
