In complicated frequency components domain, wavelet scalogram and assigned wavelet scalogram were used to further analyze vibration signals.
在频率成分较复杂的地方,利用度图和分配度图进行细化分析。

在频率成分较复杂的地方,利用度图和分配度图进行细化分析。
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,分配度图具有高的时频分辨率,可以清楚地频率成分接近的低频分量;
