Evaluating Vibration Environments Using the Shock …

18 SOUND AND Vibration /APRIL 2003 The Shock response spectra computed directly from the timehistories of simulated stationary Vibration data are comparedto the expected values for the maximum response peaks com-puted from the autospectra of the data. The data are assumedto be random with a Gaussian probability density function andthe results reveal excellent agreement when that is truly thecase. However, for the complex Vibration environment gener-ated by a repetitive Shock machine, the Shock response spec-tra computed directly from the time history data are higherthan the expected values.
