Study on Vibration of Rotor by Application of the Improved Harmonic Wavelet

摘要

Because of low attenuation speed of harmonic wavelet in time domain, we carry on the smooth processing in the frequency domain to get better quality of harmonic wavelet. With improved transaction of harmonic wavelet, this paper analyzes in subdivided frequency domain the vibration signal about rotor in normal working condition, which is distilled by the track of axes, eliminates most useless signals by calculating time domain and gets high definition graph of vibration signal in time domain at last. The fine track of axes, especially this of inferior frequency signal, well serves the analysis of rotor malfunction. The result shows greater value in practice.
