摘要 水的低粘度使得水液压轴向柱塞泵滑靴摩擦副中的水膜很薄，很容易破裂。通过模拟、分析、实验和比较，通过水的流态研究，检验新型水滑靴摩擦副的润滑特性，特别是其抗翻转能力，直接影响水膜的工作可靠性。基于多组阻尼支撑腔的思想，采用独立的刚度调节来提高水拖鞋摩擦副的抗翻转能力。此外，在N-S方程的基础上，考虑惯性、表面粗糙度等因素，更加全面、准确地考察了水液压间隙摩擦副的流体润滑特性，从而修正了经典理论提出的水液压滑靴润滑特性的计算分析结果。
Abstract The low viscosity of water makes the film of water in water hydraulic axial piston pump slipper friction pairs very thin, and which can be broken easily. By simulation, analysis, experiment, and comparison, the lubrication characteristics of the new-type water slipper friction pairs, especially its anti-turnover ability, which directly affects the working reliability of the water film, are examined by a study of water's flow pattern. On the basis of the idea of multi-groups of damping and supporting cavity, the independent stiffness adjustment is used to improve the anti-turnover ability of the water slipper friction pairs. Furthermore, on the basis of the N-S equations, the fluid lubrication characteristics of water hydraulic clearance friction pairs are examined more thoroughly and accurately, taking into account the inertia, the surface roughness etc, so as to revise the calculation and analysis results of water hydraulic slipper lubrication characteristics put forth by classical theory.
