Abstract: A stretched finite stiffness foil bent against two parallel cylinders is approximately analyzed. The difference between its length and that of a perfectly flexible foil under similar conditions, ...

Abstract: A technique for the solution of time-dependent foil bearing problems is presented in this report. Solutions obtained for typical disturbances which are introduced into the bearing indicate that ...

Abstract: Some factors useful in overcoming excessive air gaps in foil bearings are investigated. Since the gaps of interest are small, the foil bearing equations are modified to include the effects of ...

Abstract: The dynamic and static behavior of a gas lubricated bearing, consisting of stretched foil sectors, is analyzed. General equations describing the fluid film and valid for shaft excursions of the ...

Abstract: Equations for a foil over a lubricating film in which the effects of fluid inertia are taken into account are derived. Approximate solutions showing the effect of inertia and fluid compressibility ...

Abstract: Analysis of the dynamic behavior of planar foil bearings is presented for the case when both self acting and external pressurization effects are present. From it, responses to arbitrary ...

Abstract: The effect of external pressure exerted on foil bearings is studied. Analysis and numerical results are provided for its influence on the bearing gap. It is shown that a substantial reduction ...

Abstract: The effect of compressibility on foil bearings is found to be characterized by the parameter T∞ /pa r0 . Solutions are obtained for various values of this parameter. It is found that, with ...
