| Abstract: | The rotatory energy spectrum of the rotatory machinery is studied. The concept of rotatory energy spectrum is established. Two kinds of full vector energy spectrums are defined, the simple calculation equations of full vector energy spectrums based on complex signals are derived, and they have been applied to the actually fault diagnosis systems. It has been shown that the full vector energy spectrums are a very practical analysis tool to fault diagnosis of rotary machinery as a energy analysis method to process whirl signal of rotors. |
