Fault Characteristic Extraction by Fractional Lower-Order Bispectrum Methods
The generated signals generally contain a large amount of background noise when the mechanical bearing fails, and the fault signals present nonlinear and non-Gaussian feature, which have heavy tail and belong to α-stable distribution (1<α<2); even the background noises are also α-stable distri...
