基于极坐标系下修正的Reynolds方程建立了微织构机械密封表面的数学模型，并采用多重网格法进行求解，以验证微织构机械密封表面的性能。对圆柱形、方形和菱形微凸体的微织构机械密封性能进行了研究。结果表明，几何形状对摩擦系数和泄漏量有重要影响。菱形微凸体具有更好的性能。表面密度对微织构性能的影响比对微织构深度的影响更为敏感。数值方法可以作为一个有用的工程工具，分析和优化微织构机械密封的性能。
A mathematical model is established based on a modified Reynolds equation in polar coordinates, and solved by the multi-grid method to demonstrate the performance of micro-texturing mechanical seal surface. Sample cases of cylinder-shaped, square-shaped and diamond-shaped micro-asperity are studied to show the performance of micro-texturing mechanical seals. The results show that geometry has a vital influence on the friction coefficient and leakage. Diamond-shaped micro-texturing asperities have better performance than the others. And the performance is sensitive to the area density than the micro-texturing depth. The numerical approach can be a useful engineering tool, analyzing and optimizing the performance of micro-texturing mechanical face seals.
