PSD Computing
The calculation of PSD has many specialities. Simple FFT transformation solves the problem (theoretically), but in practics there are more problems. E.g.: time signal has finite length, while FFT decompose signal into a number of SIN/COS functions which are infinite, and to make it the time...- baigazin

Second task of diagnostics
There is possibility of adjusting FEM-model parameters (shell thickness, masses, etc.) with experimental vibration charakteristics (e.g. egenvalues) in some special packages. You must build and analize the FEM-model prior such an adjusting . Then the program changes properties of the FEM-model...- baigazin
