The mathematical equations of dynamic pressure of oil film were deduced according to the hydro-lubrication theory and Reynolds equations. With the comparison of the pressure in the different methods of calculation, the analysis and calculating means of the pressure and the load capacity of oil film were presented by the application software of finite element analysis, MSC. Marc. A practical sample was simulated and calculated with it. The numerous results indicate that it takes on favorable emulation effects. It can be applicable for diversified and complicated sliding bearing. Simultaneously the so precise calculating results provide a base for the stability of the rotor- bearing system.
