As compared with the power spectrum, the higher order spectrum (HOS) has three features, HOS may be used to. (1) detect the Gaussianness of a process;(2) estimate the phase of a non-Gaussian process; (3) detect the non-linearity of system. In this paper, the sensitivity of a third order spectrum of frequency response function (FRF) to the variation of structural stiffness is analysed.The HOS of FRF is introduced into the fault diagnosis.
