| 摘 要： | 小波变换具有很好的时域和频域局部化特性，为以非稳态振动为特征的信号提供了有较的分析手段。采用磁电式速度传动器测定水泵机组的振动信号，并通过小波变换处理进行故障诊断分析。结果表明，小波变换的分析方法较传统的傅立叶变换更为有效。

| Abstract: | Wavelet transform possesses excellent characteristic of time frequency localization, and provides an effective measure for analysing signal causing unstable vibration. This paper collected the vibration signal of water pump units by magnetoelectric transducer, and diagnosed the faults by a method using wavelet transform. Results showed the wavelet transform is a more efficient method in comparison with Fourier transform. |
