Signal of Roller Drilling Machine Vibration Based on Wavelet Packet Transform Real-time Detection
Tang Tianqiu · Modern Electronics Technique · 2008
Wavelet packet transform can not only detect integer harmonics of non-steady signal,but also detect non-integer harmonics,and wavelet transform is sensitive to signal of the strange point,it can be used to track roller drilling vibration signal.This paper introduces the principle of wavelet packet,the roller drilling vibration signal processing is realized based on Matlab.The signal processing has measurement functions:signal noise separation,vibration power spectrum of roller drilling mesurement,time frequency domain variety regulation of the signal of roller drilling vibration,three dimensional diagram of the signal of roller drilling vibration,companion contain noise primitive vibration wave of roller drilling and noise wave etc.Signal of the vibration of YZ-35C roller drilling in a mine is measured,actual measurement results is better than HP3562A dynamic signal analysis instrument.The result shows that this method is feasible and effective.
