5717 Molecular gas-film lubrication analyses by two dimensional CIP scheme : Pressure analyses caused by moving single projection

Abstract

Recently the spacing between the slider and the disk has been reduced to 10nm or less, and analysis of the slider dynamics becomes increasingly important. To perform this analysis, the highly accurate and numerically stable cubic interpolated propagation (CIP) method was applied to the molecular gas-film lubrication (MGL) equation. It was applied to two-dimensional dynamic pressure analysis of a finite-width slider that has ultra-small spacings by using the molecular gas-film lubrication equation. Dynamic pressures caused by moving single projeciton and running disk with step under a fixed finite-width slider were analyzed by the CIP method and are shown quantitatively.
