Dynamic-Holo-Spectrum Decomposition Technique

The rotor dynamic theory is applied to improve the traditional machine fault diagnostic and holo-spectrum analyzing method. A dynamic-holo-spectrum decomposition technique is thus advanced for describing the high frequency components of the vibration signals. Insight are gained with the theoretical basis of the decomposition principle as applied to the problem at hand.
