摘要本文提出了一个具有解析解的部分织构表面的一维等温流动模型，名义上平行。该模型允许一个简单而优雅的滑块性能特性（承载能力，摩擦力和摩擦系数）的纹理尺寸方面的参数分析。结果表明，摩擦力和承载能力实际上不依赖于细胞的数量。最佳值的设计参数（无量纲凹坑深度和无量纲纹理长度），允许最大的承载能力和最小的摩擦系数，在无量纲的形式。相同的模型被用来给出一个基于现象学的解决方案的“等效阶梯轴承”的承载能力或摩擦系数。结果表明，等效阶梯支座的概念是有问题的，因为阶梯支座的等效高度不是唯一确定的。
Abstract The article presents a one-dimensional isothermal flow model with analytical solution for partially textured surfaces, nominally parallel. The model allows a simple and elegant parametric analysis of slider performance characteristics (load-carrying capacity, friction force, and friction coefficient) in terms of texture dimensions. It is shown that the friction force and load-carrying capacity do not practically depend on the number of cells. Optimum values of design parameters (dimensionless dimple depth and dimensionless textured length), allowing for maximum load-carrying capacity and minimum friction coefficient, are presented in the dimensionless form. The same model is used to give a phenomenologically based solution for the ‘equivalent step bearing’ in terms of load-carrying capacity or friction coefficient. The results show that the concept of equivalent step bearing is questionable, as the equivalent height of the step bearing is not uniquely determined.
