Stiffness Effects on the Infinitely Wide Foil Bearing

Abstract
Numerical solutions are presented for the film thickness of the infinitely wide, self-acting foil bearing for various values of tape stiffness. The solutions indicate that with increasing stiffness there are: (a) a slow reduction in the nearly uniform clearance prevailing under most of the wrap angle; (b) an increase in the peak of the undulations occurring in the region where the tape leaves the spindle; and (c) virtually no change in the trough of these undulations.
