Abstract
The spectral structure complexity of the Mine Reducer vibration signal was analyzed. The basic theory of the vibration signal frequency demodulation analysis was introduced, The essential mode function which met the single component requirement was obtained by using Empirical mode decomposition in the Hilbert Huang Change. The instantaneous frequency was calculated, The spectrum of the instantaneous frequency was obtained by performing the Fast Fourier Transform, The spectrum analysis was done.
