This paper puts forward a new way of analyzing mutual vertical dynamic signal - pass holospectrum.

The article simply elaborates the basic principle of full spectrum,introducs with the example the application of the full spectrum to judging the move and static friction of the steam turbine units.

Based on rotor dynamics theory,this paper builds the rotating vibration equations under the period excitaion and thus deduce the theory and method of using full spectrum in precession analysis.

This paper discusses how to extract the color noise edge spectrum from the panorama spectrum and give the method to remove the influence of color noise through subtraction.

Diagnosis analysis of rotor system based on holospectrum

Study on holospectrum based on correction of phase difference

To effectively identify the illusory components in vibration signal,both rotor vibration signal of rotor with ideal shape at measurement section and illusory signal generated due to the typical shape error at measurement section are analyzed to summarize the signal characteristics adopting holospectrum method.

This paper analyzes the principle of THS(Traditional Holo-Spectrum) technique,and in allusion to the deficiency of THS that only can be used in stationary signal,a new holo-spectrum technique based on order tracking is proposed.

In this paper, theory and encoding display method of Fourier holo-spectrum are presented ,and a display system is developed.
