Acceleration FFT

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