Select on Wavelet in the SK Static Mizer with the Velocity Pulse Signal Analysis

摘要：

The velocity pulsated signals were analyzed in the SK static mixer,using Daubechies wavelet,Symlets wavelet and Dmeyer wavelet. Compared with the results,it was found that the analyzed results of the three wavelets at all levels of the energy distribution of signals had a similar trend,and the three results of the frequency analysis corresponding to the pulse peaks were very close,especially,the results of the db7 and the Dmeyer wavelet transform. Analyzing the percentage of the main signal energy value and the peaks pulse,the results showed that Sym7 wavelet transform was great different from the db7 and the Dmeyer,while the results of db7 wavelet transform were very approached to that of the Dmeyer.
