Data Fusion Based on the Vector Spectrum and Harmonic Wavelet Packet
Weiwei Li · Journal of Taizhou University · 2007
Because the running rotating machines have various signal frequency,the signal from single channel only embodies frequency and amplitude value of that direction.It cannot completely represent the information of this section.So mechanical fault diagnosis are likely to have imprecise judgment.In the paper,the vector spectrum is combined with the wavelet packet to fuse the homologous non-stationary signals,representing the information of this section.Emulation signal is used to validate data fusion based on the vector spectrum and harmonic wavelet packet.
