Study on Mechanical Mechanics with the Application of an Anti-Aliasing Wavelet Packet Algorithm in Fault Diagnosis of Rotating Machine

Abstract:

Shortcomings inhered in the canonical wavelet packet algorithm are explained in detail. An anti-aliasing wavelet packet algorithm is proposed. The method is used to analyze a typical simulation signal and a vibration signal measured from a gear box in wind generator to study the mechanical mechanics. The results show that the improved algorithm is quite effective in overcoming the shortcomings of the canonical method. It can extract the characteristic frequencies of rotating machine precisely and effectively.
