| Abstract: | Differential equations of air film in elastic bump foil journal bearing were deducted by the perturbation method with air lubrication Reynolds equation and series expansions of air film,air film thickness and foil deformation.The mathematics model of the relations among air film thickness,bump foil deformation and air film pressure was developed in consideration of air compressibility.Both finite difference method and Newton-Raphson method were applied to solve the coupled differential equations and air fil... |
