本文介绍了一种研究流体动力润滑状态下织构表面的解析方法。为此，提出了一种积分具有表面不连续性的滑动轴承雷诺方程的方法。通过引入适当的无量纲参数，给出了缩进和投影形式下各种纹理轮廓的解析关系。这些关系表达了纹理轴承性能测量与几何/运行参数之间的数学依赖性质。采用优化方法获得了优化的毛化参数，以提高非对称部分毛化滑动轴承的最大承载能力、承载能力与润滑油流量比和最小摩擦系数。(C)2010爱思唯尔有限公司。保留所有权利。
This paper introduces an analytical approach to study the textured surfaces in hydrodynamic lubrication regime. For this purpose, a method of integrating the Reynolds equation for slider bearings with surface discontinuities is presented. By introducing appropriate dimensionless parameters, analytical relations for various texture profiles in both indented and projected forms are delivered. These relations express the nature of mathematical dependence between textured bearing performance measures and geometrical/operational parameters. An optimisation procedure is employed to achieve the optimum texturing parameters promoting maximum load capacity, load capacity to lubricant flow rate ratio and minimum friction coefficient for asymmetric partially textured slider bearings.
