Abstract
Aridged foil journal bearing having a finite length and lubricated with an incompressible fluid was analytically investigated in order to understand and quantify its behavior. Film rupture has been accounted for by employing swift-stieber boundary conditions.The governing equations were numerically solved for a length to diameterratio of unity. The equation is solved by using finite difference technique. The charts are presented for the acndimensional pressure at the median plane and for the effect of changing eccentricity on the pressure distribution. Acomparison hasbeen made between foil bearing and journal bearing to clarify the differences between them.At the same e the charts illustrate that the positive pressure occupies a larger portion of the bearing circumference in the foil bearing than the journal bearing andtheangularlocation of minimum film thickness increases from 200’ in journal bearingto 250’ in foil bearing. This property is advantageous from the standpoint of bearing stability.The bearing load for the foil bearing is less than that for journal bearing.
