小波分析在深孔加工刀具故障诊断中的应用

Wavelet analysis and its application in the cutter fault diagnosis of deep-hole processing

在小波分析的理论基础上 ,讨论小波包在故障信息提取中的应用。小波包频段能量故障特征提取方法 ,克服了传统的信号处理方法不易提取微弱故障信息的不足。

On the theoretical basis of wavelet analysis,wavelet packet and its application in the extraction of fault information are discussed The method of frequency energy based on wavelet packet is given So it overcomes the shortage of extracting the weak fault information difficultly by conventional signal processing method And the practicability of this method is illuminated by an example.
