      Not sure what the question is. Please try to be more specific.nnDo you have measured experimental frequencies between 30-250 Hz from a modal test (physical test), and you are not getting that in the modal FE results shown?.if that is the case check dimensions of part, material properties, units, etc, to see if there is a mistake in the FE model.nnSomething else, is that he part is quite short (~ 150 mm) so I would not expect any freq. (at least if it is made of metal) say between 30-200 Hz.nnAll the bestn

      Please adjust the FFT frequency. You may be oversampling the acoustic signal.
