Abstract

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 analysis (HOSA) had been reported to be effective in providing information on nonlinear response. Bispectrum as one of higher order signal analysis tools found to be a useful tool in identifying nonlinear behavior of mechanical system due to vibration faults. This paper provides an introductory treatise of to Bispectrum, and reviews its applications in machinery vibration faults detection that includes misalignment, bearing and gear faults, and cracked shafts. The effectiveness and limitation of this technique are also reported for these faults based on published literature
