Full Spectrum Analysis Technology and Its Application in Fault Diagnosis

The clew of full spectrum is introduced, the theory relationship between the full spectrum and the signals of the rotary machinery are studied, and the theory calculation formula and simple numerical method of full spectrum based on complex signals are deduced, and they are applied to the actual fault diagnosis systems. It shows that as an analysis method of comprehensively processing whirl signals of rotors, the full spectrum can clearly deal with the relationship between the orbits and positive/negative eddy. Through the simple conversion, we can also identify the turning intention of the rotors, and it is a very practical analysis tool for fault diagnosis of rotary machinery.
