Wavelet Processing Method of Random Vibration Signal

WANG Jia-feng (Institute of Electronic Engineering, China Academy of Engineering Physics, Mianyang 621900, China)  
Use wavelet transformation to process the random vibration signal. At first, adopt wavelet transformation to process the random vibration signal and the analyzing level is confirmed by precision; then, carry out time zone segment for frequency zone signal, make sure the segment is directly proportional to the center frequency of frequency zone, therefore the time differentiate rate is directly proportional to the center frequency; at last, acquire the average rate of segment data, combine the data of all frequency and time zone and compose the compressed time frequency distributing. The results show that the wavelet transformation processing method can reflect the time frequency feature of random vibration signal.
