摘要
A method for dynamic analysis of a rotor-journal bearing system, in which large dynamic loads act on the rotor, is introduced. The governing equations are solved by numerical calculation. The system is analyzed as a coupled problem regarding the equations of motion for a rigid rotor and the Reynolds equations for the oil film in all the bearings supporting the rotor. Then, an analysis method for when a relative misalignment exists between the bearings is also presented. A rigid rotor supported by three bearings was analyzed for use in rotary compressors. The rotor motion, the bearing load characteristics and the misalignment influence are shown as the results of the analysis.
