Abstract

In order to investigate the vibration characteristics of the reciprocating compressors for the offshore platform, the vibration from the reciprocating compressor is analyzed by applying the harmonic wavelet packet transform. The energy distribution characteristics of vibration signal under the different frequencies are discussed. Results show that the vibration energy of the reciprocating compressor is mainly concentrated in the low frequencies of 25 Hz and 50Hz in the horizontal and vertical directions, and the vibration energy in other frequencies is small and smooth. In the axial direction, the vibration energy of the reciprocating compressors 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.
