摘 要： Purpose - According to the Christensen stochastic roughness model, the purpose of this study is to developing a modified Reynolds equation to investigate the effects of surface roughness and molecular rarefaction on ultra-thin compressible and isothermal gas lubrication. Design/methodology/approach - Basing upon the average film thickness method with three adjustable coefficients, the higher order slip-flow velocity distribution was accommodated. Findings - Compared to the smooth case, the longitudinal roughness improves the pressure distribution and load carrying capacity, while the effect of transverse roughness is opposite to that of longitudinal one. The molecular rarefaction effect may diminish the built-up air bearing pressure and reduce the roughness effect on load carrying capacity. The squeeze number has evident effect in depression of maximum pressure of slider rail with transverse roughness. Originality/value - Combing the high-order slip-flow model and Christensen roughness model, this research paper proposed a feasible study of the analysis of molecular rarefaction effect on slider air-bearing system.

目的——根据Christensen随机粗糙度模型，本研究旨在开发一种修正的雷诺方程，以探究表面粗糙度和分子稀疏对超薄可压缩等温气体润滑的影响。设计/方法——基于具有三个可调系数的平均膜厚法，拟合了高阶滑移流速度分布。结果——与光滑表面相比，纵向粗糙度改善了压力分布和承载能力，而横向粗糙度的影响则与纵向粗糙度相反。分子稀疏效应可能降低空气轴承的积聚压力，并减弱粗糙度对承载能力的影响。挤压数在横向粗糙度下显著影响滑块轨道的最大压力降低。原创性/价值——本文结合高阶滑移流模型与Christensen粗糙度模型，提出了对滑块空气轴承系统中分子稀疏效应进行分析的可行研究。
