【Abstract】 Critical speed is one of the important dynamic parameters of the rotor system in centrifugal compressor. Especially, it is very difficult of identify the high order critical speed of one rotor system during its trial run. In this paper, the vibration signals of rotor system are analyzed using harmonic wavelet, then the high order critical speed is identified. The final result is satisfactory.更多还原
