Definitions

  • the invention relates to the automated performance of sound samples on multi-component components, such as blade associations, are recognized in the pattern.
  • the problem is the subjective, potentially error-prone assessment on the one hand and the time-consuming disassembly of the component on the other hand.
  • the object is achieved by a method according to claim 1 and a device according to claim 2.
  • distinctive characteristics of the sound image such as the temporal change of the frequencies, the frequency response and the decay behavior can be determined.
  • Other liberis ⁇ tics of the acoustic analysis methods can also be used.
  • FIG. 1 shows a frequency image 1 of one or more components when new or before the first use.
  • FIG. 2 shows a frequency image 2 of a used component according to FIG.
  • Both the intensity I and the position of the frequencies f have at least partially changed or shifted.
  • the pattern recognition recognizes the deviation from the nominal state and assigns the blade rows as a component of a further classification such as "acceptable” or “interchangeable.” These classifications are determined beforehand on the basis of preliminary examinations and existing measurements.
