Comparing the spectrums of a rotor system with pedestal looseness in the literature [3, 4], the spectrum not only contains the fundamental frequencies of inner and outer rotor, 1/2 fractional harmonic components, but also contains sum frequency and difference frequency of two rotors' fundamental frequencies, and superharmonic frequencies (such as 2X, 3X, and 4X) are presented.
