Foil Bearing Investigation. Reduction of Air Films in Magnetic Recording by External Air Pressure.

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 in film thickness can be achieved by applying small pressures in the inlet zone. The effect of several pertinent parameters is presented and discussed.
