Application of bispectral analysis in vibration fault detection:a review

Mechanical system degradation always leads to the unstable and nonlinear characteristics in the dynamic responses of the system to some extent. Conventional spectral methods based on Fourier transform have limited value in showing up fault information deviating from linearity. Higher order spectral...
