Abstract:
Critical speed is one of the important dynamic pararameters of
the rotor system in centrifugal compressor. With the rotational
speed increasing, the problem of passing the two or more higher
order critical speed is appeared, so it is very important to
identify the high-order critical speed of one rotor system
during its trial run. The vibration signals of rotor system are
analyzed by harmonic wavelet I then the high-order critical speed
is identified. The final result is satisfying.
Key words:
Harmonic
wavelet Rotor system Critical speed
