Research to achieve a reasonable distribution of the slip zone of the sliding pair for better improvement of the hydrodynamic pressure of the liquid film is an intractable topic. To solve this issue, this paper takes the thrust bearing as the research object, and proposes to use the position number of the grid nodes at the boundary line between the slip and no-slip zone in each radial zone of the inclined pad to be variables. The variables are then defined as chromosomes in an adaptive genetic algorithm (AGA) and used to optimize the bearing capacity of the tilting pad. The results show that the optimal method of the AGA, which has good stability and repeatability, remarkably improves the distribution of the slip zone on the surface of the inclined pad. Therefore, the bearing capacity of the liquid film is significantly improved. Particularly, by using the optimization, the boundary line between the slip/no-slip zone is a composite form of a part of an arc and a part of the whisker. When the liquid flow through the heterogeneous slip/on-slip surfaces is used by this composite splicing method, the liquid pressure is upgraded in two steps. This is more conducive to increasing the pressure on multiple areas on the surface of the tilting pad, thereby achieving higher bearing capacity.
为了实现滑动副滑动区的合理分布，从而更好地改善液膜的流体动力压力，这是一个复杂而棘手的问题。为解决这一难题，本文以推力轴承为研究对象，提出将倾斜垫片各径向区域中滑动区与非滑动区交界处网格节点的位置数作为变量。随后，将这些变量定义为自适应遗传算法（AGA）中的染色体，并用于优化倾斜垫片的承载能力。结果表明，采用AGA优化方法具有良好的稳定性和重复性，显著改善了倾斜垫片表面滑动区的分布，从而大幅提升了液膜的承载能力。特别是通过优化，滑动/非滑动区的边界由部分弧线和部分“刷状”结构组成。当采用这种复合拼接方式，使液体在异质滑动/非滑动表面上流动时，液压得以分两步提升。这有助于增加倾斜垫片表面多个区域的压力，从而提高承载能力。 |
