表面织构的研究正从单一的宏观织构向微纳米复合织构发展。目前对织构减摩机理和理论模型的研究还比较薄弱。研究不同类型表面纹理的特点，确定每种纹理适用的工作条件是当前研究的重点。本文基于Navier-Stokes方程建立了流体动力润滑的数学模型。利用FLUENT软件对4种纹理模型进行仿真分析，探索不同纹理类型的动压润滑特性，为纹理优化提供数据支持。通过仿真数据得到数学模型所需的关键变量值。通过摩擦磨损实验，测定了不同工况下该织构的摩擦系数，并用实验结果验证了数学模型的正确性。研究结果表明：圆形织构适合中低速高负荷工况，人字形织构适合中高速高负荷工况，沟槽织构适合高速低负荷工况，复合织构适合高速高负荷工况。将实验结果与数学模型得到的结果进行比较，发现两者在不同纹理的减摩性能排序上基本一致，在摩擦系数值上存在10%-40%的误差。提出了流体动力润滑的数学模型，确定了最优表面织构模型的求解方法。
AbstractThe research on surface texture is developing from single macro-texture to composite micro-nano texture. The current research on the anti-friction mechanism and theoretical models of textures is relatively weak. Studying the characteristics of different types of surface textures and determining the applicable working conditions of each texture is the focus of current research. In this paper, a mathematical model of hydrodynamic lubrication is established based on Navier–Stokes equations. The FLUENT software is used to simulate and analyze the four texture models, explore the dynamic pressure lubrication characteristics of different texture types, and provide data support for texture optimization. The key variable values required by the mathematical model are obtained through the simulation data. The friction coefficient of the texture under different working conditions was measured through friction and wear experiments, and the mathematical model was verified by the experimental results. The research results show that circular texture is suitable for low to medium speed and high load conditions, chevron texture is suitable for medium to high speed and medium to high load conditions, groove texture is suitable for high speed and low load conditions, and composite texture is suitable for high speed and medium to high load conditions. Comparing the experimental results with the results obtained by the mathematical model, it is found that the two are basically the same in the ranking of the anti-friction performance of different textures, and there is an error of 10%−40% in the friction coefficient value. In this study, a mathematical model of hydrodynamic lubrication was proposed, and the solution method of the optimal surface texture model was determined.
