摘要

摩擦副表-界面的微型结构具有减少摩损、提高润滑性能等作用。在动、静环摩擦端面开设微槽与微孔的复合微造型跨尺度润滑气膜计算域模型，利用独有block映射技术的ICEM软件进行结构化网格划分，并对流场进行数值模拟。以密封的工况条件为出发点，结合微造型结构尺寸，从气膜开启力、泄漏量、润滑气膜摩擦系数及壁面剪切力四个方面展开讨论，结果表明：在介质压力和转速相同时，微孔的覆盖比对气体密封性能影响较大，增幅为5%～8%，并且当覆盖比为50%时气体密封的性能可达到最佳。之后以此为基准改变该模型微孔的密度、深度、直径，通过研究四种参数的变化规律发现微孔的密度和直径对密封性能提升较大，增幅为7%～8%，并且微孔密度为12.5%，深度为10 μm，直径为400 μm时气体密封性能可达到最佳水平。

Abstract

The microstructures between the relatively sliding friction pair surface-interface can reduce attrition and improve lubricity. Computational domain model of cross scale lubrication film with micro-holes and micro-grooves on static and move rings were established. The lubrication film structured grids were meshed by the software ICEM with unique block mapping technology. Then the Fluent was used for numerical simulation. Taking the working conditions of the seal as the starting point

combined with the size of the micro-modeling structure

the paper discusses the four factors: the film opening force

the leakage amount

the friction coefficient of the lubricating film and the wall shearing force. The results showed that under the same medium pressure and rotational speed

the coverage ratio of micro-holes have a greater impact on the performance of gas sealing

and the increase is 5% to 8%

the gas sealing performance can achieve the best level when the coverage ratio of micro-holes is 50%. After that

the density

depth and diameter of the friction pair interface of the model were changed according to this criterion. It was found that the density and diameter of the micro-hole could significantly improve the sealing performance by 7% to 8%. And the gas seal performance can reach the best level when the micro-hole density is 12.5%

the depth is 10 μm and the diameter is 400 μm.
