Abstract

The purpose of this paper is to analyse the basic characteristics, which include the hydrodynamic effect caused by the high rotating speed of the spindle, and to propose the optimal design principle which attains the maximum stiffness of the bearing. The finite element method with the Galerkin criterion is applied to solve the nonlinear Reynolds equation, and the pressure distribution of the lubrication film is numerically caculated.
