对小波包分析应用于故障诊断进行了研究，利用仿真出来的故障数据，将快堆钠泵非平稳时变振动信号分解到不同层次和不同频带上，有效地提取出反映钠泵不同故障的特征向量，在识别中得到了满意的结果。

The wavelet packet analysis applied in fault diagnosis system is studied in this thesis. Using simulation fault data, uncalm and time difference vibration signal of sodium pump are decomposed on different levels and frequencies. To picked-up the eigenvectors reflecting different fault of sodium pump with availability, simulation results have shown its satisfaction in the identification.
