本文描述了一个粗糙的，静止的表面和一个光滑的，运动的表面之间的椭圆接触的弹流润滑（EHD）的分析结果。粗糙度呈正弦形槽的形式，这些槽沿润滑剂夹带方向的横向排列。所分析的条件被选择为对应于高速、高温盘式机器的操作条件。结果的主要特征是出现的粗糙度几乎完全变平，伴随着压力分布中相应的涟漪。还分析了三维粗糙度的接触，这表明与二维情况相比，纵向凹槽倾向于持续存在。
The paper describes the results of the analysis of elastohydrodynamic (EHD) lubrication of an elliptical contact between a rough, stationary surface and a smooth, moving surface. Roughness takes the form of sinusoidal grooves aligned in the direction transverse to that of lubricant entrainment. The conditions analyzed are chosen to correspond to the operating conditions of a high speed, high temperature disk machine. The main feature of the results is the almost complete flattening of the roughness that occurs, accompanied by a corresponding ripple in the pressure distribution. A contact with three-dimensional roughness has also been analyzed, and this shows that in comparison with the two-dimensional case, the longitudinal grooves tend to persist.
