The method for the dynamic analysis of a rotor-journal bearing system in which large dynamic loads act on the rotor has been applied to an elastic flexible rotor system. In this analysis, the momentum equations of the rotor are transformed into ordinary differential equations by the finite element method. Journal bearings are approximated by the short bearing theory, and the bearing loads which act on the rotor are given by the Reynolds equations for oil films. The system is solved as a coupled problem of the momentum equations and the Reynolds equations for all the bearings. A rotor system for rotary compressors has been analyzed by the present method. The rotor action, bearing load characteristics and pressure distributions of oil films are thus determined.
