Study of Vibration Characteristics of the Reciprocating Compressor on the Offshore Platform Based on Harmonic Wavelet Packet Transform

Abstract:

In order to determine the vibration characteristics of the reciprocating compressor on the offshore platform, the vibration signal from the reciprocating compressor on the offshore platform was investigated by applying the harmonic wavelet packet transform. The energy variation of vibration signal under the different frequencies was discussed. It was shown that the vibration energy of the reciprocating compressor in the horizontal and vertical directions is mainly concentrated in the low frequency of 25Hz and 50Hz, and the vibration energy of other frequency is small and smooth. In the axial direction, the vibration energy of the reciprocating compressor extends to the medium-high frequency, and the large energy appears in the 225 Hz. Therefore, the harmonic wavelet packet transform can be used to research the vibration characteristics of the reciprocating compressor on the offshore platform.
