Definitions
- the invention relates to the automated implementation of sound samples on multicomponent components, such as bands, in which patterns are recognized.
- the object is achieved by a method according to claim 1 and a device according to claim 2.
- FIG. 4 shows a component with which a sound test is carried out and a measuring arrangement for carrying out the sound test.
- the description and the figures represent only exemplary embodiments of the invention.
- the aim is to provide the sound pattern of a new part or a technically approved component, in particular a row of blades, for pattern recognition.
- the sound pattern of a row of blades must first be assigned. With direct excitation of the row of blades e.g. With a hammer blow, the exact airborne sound and the relevant relevant frequency images can be assigned directly to the row of blades.
- the assignment of the measured signals to a row of blades is problematic. However, this problem can be solved by individual measurement in the new production.
- the frequency images of the new condition are stored in a database and are known as blueprints. These blueprints are assigned to a pattern recognition and assigned as a "healthy" row of blades. Alternatively, the frequency images of new components can also be calculated numerically using the finite element method.
- Striking characteristics of the sound pattern such as the change in frequency over time, the frequency response and the decay behavior can also be determined.
- Other characteristics of the acoustic evaluation methods can also be used.
- the signals are evaluated accordingly and fed to the pattern recognition.
- FIG. 1 shows a frequency image 1 of a component 100 (FIG. 4) when new or before it is used for the first time.
- the intensity I and the frequency f are plotted. You can see different, not necessarily discrete frequencies with different intensities that are typical for a new component. This is just an example of an acoustic parameter.
- FIG. 2 shows a frequency image 2 of a component 100 according to use according to FIG. 1.
- Both the intensity I and the position of the frequencies f have at least partially changed or shifted.
- FIG. 3 showing a decay behavior 4 for new components and curve 7, here dashed, representing the decay behavior of a used component.
- the decay behavior 4, 7 is only one example of an acoustic parameter.
- the pattern recognition recognizes the deviation from the target status and assigns the blade rows as a component to a further classification such as "acceptable” or "to be exchanged". These classifications are determined beforehand on the basis of preliminary examinations and existing measurements.
- Figures 1, 2, 3 represent exemplary patterns that are created from the recordings of airborne sound.
- FIG. 4 shows a detail of a blade dressing 10.
- the dressing blade 100 includes a plurality of circumferentially Rich ⁇ tung 200 on a rotor 300 arranged as a turbine ⁇ shovel formed blades 11 ', 11'',11'''.
- the turbine rotor blades essentially comprise a rotor blade 500 which is formed between a cover plate 14 and a blade root (not shown in more detail).
- the rotor blade blade 500 is designed in such a way that a flow in the direction of the axis of rotation 700 is deflected with thermal energy in such a way that the thermal energy is converted into rotational energy of the rotor 300. To do this, the rotor blade 500 is profiled.
- the Deckplat ⁇ th 14 ', 14'',14''' are arranged in the circumferential direction 200 hinte purely other.
- the cover plates 14 ', 14' ', 14' '', ... are designed as Z plates.
- the blade root, not shown, is designed as a hammer base.
- a cover plate 14 ', 14'',14''', ... a force to a Benach ⁇ disclosed cover plate 14 ', 14'',14''', ... exercises.
- the cover plates 14 ', 14'',14''', ... are thereby biased against each other.
- the rotor 300 rotates about the axis of rotation 700 at a frequency between 25 Hz and 60 Hz. Larger frequencies are also possible. At these frequencies, a centrifugal force takes place which causes the rotor blades 11 ′, 11 ′′, 11 ′′ ′′ to move in the radial direction 800, which is caused by the blade root, which is held in a groove in the rotor 300 , is prevented.
- the radial direction 800 is in this case from the rotation axis 700 along the longitudinal substantially form a blade 11 ', 11'',11''', ....
- Figure 4 is also the implementation of the sound sample Darge represents by means of mechanical excitation, for. B. a Ham mer 17, which is controlled manually or by a pulse generator and can be carried out directly.
- Component 100 is a vane assembly, here a cover band 14 ', 14' ', 14' '', ... of a turbine vane 11 ', 11' ', 11' '', ... is excited, preferably only a component of the multi-component component (100).
- the microphone 20 is commercially available and converts the measured sound vibrations directly into electronic data.
- the electronic data are transmitted with a cable 23 or other type of transmission to a cell phone or mobile electronic device 26 which has a program or an app by means of which the electronic data can be recorded and analyzed and to a service technician directly a recommendation and statement can spend.
