- Vibration Response Spectrum
- License: Freeware
- Price: 0.00


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 equation.
