Display Imported File Statistics. The software design response spectrum If it is desired that each of the accelerograms best matches the design spectrum, then formula 2 can be directly applied to determine a spectrum-compatible PSD. Iterations on the frequency content of the accelerogram are performed to adjust the spectral match”one-by-one”that is for each of the synthetic The PSD describes how the power of a signal or time series is distributed with frequency. The power of the signal in a given frequency band can be calculated by integrating over the frequency values of the band.

A vibration response spectrum is a really powerful yet underutilized tool by design engineers. It takes a PSD and then calculates the response of a hypothetical system for a range of different natural frequencies of that system. It tells you what frequencies to avoid in your design and how your system will react.

The compatibility between a design response spectrum and the corresponding target PSD function describes in the sense of expectation (on average) how well the response spectrum of a synthetic time history generated from the target PSD function converges to the design spectrum. A response-spectrum-compatible power spectral density (PSD) is used in design of nuclear power plants to circumvent costly time history analysis. Several methods are available for identifying the Power Spectral Density (PSD) and Shock Response Spectrum (SRS) analyses have been used in packaging laboratories for a number of years, but often with limited understanding of the underlying concepts.
