基于小波—Hilbert解调的齿轮故障诊断方法
Published 2013-01-01“…A method of gear fault feature extraction based on wavelet transform and Hilbert demodulation is proposed.On the basis of fault mechanism and characteristic frequencies of gearbox fault,wavelet transform is used to decompose the vibration acceleration signals of gear faults into different frequency bands,thus realizing the extraction of nonlinear coupling characteristic frequency of gear fault,which is then used to achieve accurate fault information by Hilbert demodulation.The result shows that the proposed method can effectively improve the frequency resolution and realize accurate extraction of fault feature,and it has certain practical value for the gear fault diagnosis of automobile gearbox when applied to the automotive industry.…”

Communication emitter individual identification based on 3D-Hibert energy spectrum and multi-scale fractal features
Published 2017-04-01“…For communication emitter identification,a novel method based on Hilbert-Huang transform (HHT) and multi-scale fractal features was proposed.First,the time frequency energy spectrum was derived via HHT,which was called a complicated curved surface in the three-dimension space,namely,3D-Hilbert energy spectrum.Then,the differential box dimension and the multi-fractal dimension was extracted to compose the feature vector under multi-scale segmentation using fractal theory.Finally,communication emitter individual identification was obtained using the two dimensions of features above and the support vector machine (SVM).Moreover,the novel method was compared with two existing methods to identify simulated and actual signals with different and the same modulation modes,respectively.Results show that the identification rate of the novel method is higher than that of the two other methods.The features extracted by the novel method have high stability,sufficiency,and identifiability,also outweigh the negative effects of the change of signal-to-noise ratio and the number of training samples and emitters.…”
