Abstract
The disclosure is directed to a method comprising the steps: carrying out multiple measurements on a mechanical object, the measurements each differing by one or more parameters influencing the measurement; determining a spectrogram on the basis of the measurement data of the measurements and depending on a predefined parameter of the mechanical object; determining one or more excitations of the mechanical object; reproducing the excitations in the spectrogram.

A method for analyzing a movement behavior of a mechanical object, comprising the steps of:
- carrying out multiple measurements of a mechanical movement, using position-based methods and/or force-based methods at a large number of measuring points on the mechanical object, the measurements of the mechanical movement each differing by one or more parameters influencing the measurements of a mechanical movement, wherein the one or more parameters includes a rotational speed of the mechanical object;
- wherein the mechanical object is a rotating blade disk mounted on a shaft;
- determining a first partial spectrogram on the basis of measurement data of the measurements of a mechanical movement and depending on a predefined parameter of the mechanical object for selection of the measurement data of the measurements;
- determining a second partial spectrogram on the basis of measurement data of the measurements of a mechanical movement and depending on a predefined parameter of the mechanical object for selection of the measurement data of a measurement;
- fusing the first partial spectrogram and the second partial spectrogram into a composite spectrogram;
- determining one or more excitations of the mechanical object;
- the excitations being maximum amplitudes for the spectrogram;
- displaying the excitations of the mechanical object in the composite spectrogram;
- and
- balancing the mechanical object.
