Description
Summary:This procedure was developed for validating pyroshock data by Powers and the author, using techniques originated by Gaberson and Chalmers in validating naval shock data at lower frequencies and subsequently modified. It requires that the acceleration time history be single and double integrated to obtain a velocity and a displacement time history, which is to be examined. Valid data look like a low-pass filtered acceleration time history which is not integrated. The maximum resulting displacement should approximate the independently measured displacement (often near zero) or that previously computed analytically for the structure at the measured location. In addition, the positive and negative SRS are computed and compared. Valid data usually show similar spectral content.
