This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD).The base input PSD must be in terms of acceleration.The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles...
