Displacement FFT

Displacement FFT (Fast Fourier Transformations) Spectrum – transition from Time History to Frequency Domain. The AVA Software provides a visualization of the amplitudes of the speed vibrations of the point, at different frequencies. The amplitudes of the displacements in the frequency spectrum normalized by absolute values ​​are shown. These values ​​are used to estimate the degree of impact in cases where norms limit the permissible PPDs, as a function of frequency. The AVA Software provides fast interactive movement and scaling of graphics. If desired by the user, the Displacement FFT graphs can be saved in DXF or tabular format. These Displacement FFTs can be used to estimate vibration frequency amplitudes.
