The model of multi-phase flow oil film of journal bearing was established on CFD (computation fluid dynamics) method in order to ensure the stable operation and obtain the dynamic characteristics. The radial and tangential forces of multi-flow oil film with three tiny eccentric positions were calculated, then, the stiffness and damping coefficients were reached. Compared from other results, the ones in this paper are accuracy, providing an important value on the stable and high efficient operation of journal bearings.
