【Abstract】 Based on the design requirements of the API617 standard, the rotordynamic characteristics of a centrifugal compressor are analyzed in this paper. First, a model of the rotor-bearing system is established. Subsequently, the critical speed is calculated and the corresponding computational result is assessed based on the requirements of API 617. Finally, the stability analysis is conducted. The results are shown to be useful for the compressor design.更多还原
