摘要

为研究海洋平台往复压缩机的振动特征，应用谐波小波包变换对往复压缩机的振动进行分析，探讨不同频率下振动信号的能量分布特征.结果表明，在水平方向和垂直方向，往复压缩机振动能量主要集中在25 Hz和50 Hz的低频处，其他频率振动能量小，变化平稳；在轴向，往复压缩机振动能量向中高频扩展，在225 Hz处出现较大值.因此，谐波小波包变换可用于往复压缩机振动特征研究.

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.

Key words： harmonic wavelet packet; reciprocating compressors; vibration; energy
