中文摘要：

通过建立凹坑形仿生非光滑表面滑靴副的全水动压润滑模型,采用CFD方法及正交试验法研究工况参数（膜厚、转速）及几何参数（坑形、面积率、深径比）对流体动压润滑性能和水膜承载力的影响规律。研究结果表明：凹坑表面产生的承载效应是其静压和动压分布的综合,其中具有凹坑形仿生非光滑表面的斜盘与滑靴相对运动而引起的动压效应起主要作用;工况参数和几何参数对水膜承载力的影响顺序为转速〉膜厚〉坑形〉深径比〉面积率;膜厚30μm、转速3 000 r/min、面积率20%、深径比0.5的三角柱坑为最优水平组合。该研究结果可为高压海水轴向柱塞泵仿生非光滑表面斜盘的设计提供参考。

英文摘要：

A hydrodynamic lubrication model of slipper/swash-plate pair with bionic non-smooth concave surface is established. The CFD method and the orthogonal experiment method are employed to investigate the effect of operating parameters（film thickness、rotate speed） and geometric parameters（concave shape、area ratio、depth to diameter ratio） on the hydrodynamic lubrication performance and the load carrying capacity of seawater film. The research results show that the load carrying effect from concave surface is a combination of static pressure distribution and dynamic pressure distribution, and the dynamic pressure effect caused by the relative motion of slipper-pad and swash-plate with bionic non-smooth concave surface plays a main role; the sequence of operating parameters and geometric parameters for load carrying capacity is rotate speed film thickness concave shape depth to diameter ratio area ratio; the triangular prismatic concave with film thickness of 30 micrometers、speed of 3 000 r/min、area ratio of 20% and depth to diameter ratio of 0.5 is the optimal level combination. The research results provide reference for the design of swash-plate with bionic non-smooth surface of high pressure seawater axial piston pump.
