- W2389635076 abstract "With the reputation of compact structure and high efficiency,integrally geared centrifugal compressor has been widely used in the modern process industry. However,because of the characteristics of bearing depend on the load of compressor,analyse the rotor dynamics of this type compressoris extremely complex. Based on the theories of rotor dynamics and gear meshing,the finite element model of a gear-bearing-rotor system was established to take into account the axial-lateral-torsional coupling effect based on a certain compressor. First of all,the model analysis on rigid support and unbalance analysis of the single shaft on flexible support were conducted. Comparingwith the measured results,the analysis results were reliable and have high accuracy. On this basis,the investigationindicatesthat the changing of the bearing stiffness coefficient caused by bearing load variation hasan effect on rotor critical speed and unbalance response. Also,the transfer characteristics between the rotors unbalance vibration was contrasted and analyzed. Results show that rotors vibration will increase with the increase of the compressor load,and gear mesh will increase the rotor vibration on the sensitive degree of imbalance. The result of this research can provide certain theoretical reference for the design of the integrally geared centrifugal compressor and compressor fault diagnosis based on the model." @default.
