In complicated frequency components domain, wavelet scalogram and assigned wavelet scalogram were used to further analyze vibration signals.
在频率成分较复杂地方,利用小波尺和分配小波尺行细化分析。

在频率成分较复杂地方,利用小波尺和分配小波尺行细化分析。
Results show that reassigned wavelet scalogram has higher time-frequency resolution than wavelet scalogram and can well identify such close low-frequency components.
结果表明,分配小波尺具有频分辨率,可以清楚地识别出频率成分接近低频分量;
