Abstract
The critical speed is one of the important dynamic parameters of the rotor system in a centrifugal compressor. With the increase of rotation speed the two or more higher order critical speed appears. So it is very important to identify the high-order critical speed of one rotor system during its trial run. The vibration signal of the rotor critical speed has been analysed and identified by means of harmonic wavelet in its trial run. The final result is satisfactory.
