A close look at the measurement of shock data - Lessons learned
Abstract
Pyroshock testing and analysis is one of the most difficult regimens in the field of structural dynamics. The harsh and often-unpredictable environment has caused relatively poor behavior of the measurements systems used, often for reasons that were not well understood. This paper reports on a study that was performed with the goal of better understanding of the problem areas and development of methods for improving results. Specific areas addressed include: (1) characterization of the broadband response and evaluation of its effects on standard measurement systems, (2) transducer mounting and cabling techniques, (3) the measurement of in-plane motion, and (4) the problem of justifying/normalizing the results obtained by different data acquisition systems.
