In complicated frequency components domain, wavelet scalogram and assigned wavelet scalogram were used to further analyze vibration signals.
在成分较复杂的地方,波尺度图和分配波尺度图进行细化分析。

在成分较复杂的地方,波尺度图和分配波尺度图进行细化分析。
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,分配波尺度图具有高的时分辨,可以清楚地识别成分接近的低分量;
