Validation of Pyroshock Data

Abstract

This paper presents a comprehensive description of pyroshock, the interpretation of pyroshock data, and the validation of pyroshock data. Recent events in the pyroshock testing community show that corrupted pyroshock data are still being acquired at government agencies and private companies. A large part of this paper is devoted to acquisition and analysis of pyroshock data because proper time-history data acquisition and, consequently, test specification development are common industry problems. To avoid corrupted pyroshock data and thus corrupted pyroshock specifications, recommended practices for instrumentation and data acquisition systems as well as data analyses are provided. Causes of corrupted pyroshock data are explored and recommendations for avoiding corrupted pyroshock data are presented.
