Abstract
This paper presents a new numerical foil-bearing analysis method for two-dimensional foil-bearing problems based on the inverse analysis concept. This method efficiently and reliably provides a convergent solution for a specified bearing surface configuration with a large penetration. Conventional numerical foil-bearing analysis methods are reviewed first, and the problems inherent in the iterative calculation method for nonlinear governing equations are discussed. Then, the substitution iteration algorithm alternating between the time-independent Reynolds equation and the static foil deflection equation is reformulated as the iterative inverse analysis procedure of a set of self-consistent solutlons whose bearlng contour can approach the given value as rapidly as possible. As examples of the numerical calcuIation, a cylindrical foil bearing with a head wrap length of an actual computer tape head is analyzed. Converging characteristics and calculated results are presented.
