Application of wavelet transform to detectione of decelerator
Ruyi Zheng · Coal Mine Machinery · 2003
Wavelet transform is a kind of singal analysis method in time - frequency plane. Compares with fourier transform, wavelet transform is more fit for fault diagnosis because it is more effective for nonstationary singal. This paper discusses applications of wavelet transform in niose elimination and identifying facility fault state by practical singal of decel-erator.
