NASA TECHNICAL HANDBOOK-DYNAMIC ENVIRONMENTAL CRITERIA
This handbook is approved for use by NASA Headquarters and all field centers and is intended to provide a common framework for consistent practices across NASA programs. A concerted effort is underway within the NASA engineering community, under the cognizance of the NASA Office of the Chief Engineer, to promote more consistent practices across the NASA centers in the areas of dynamics and structures design and test criteria for spacecraft and payloads. This effort has resulted in NASA standards in the fields of structural design and test factors of safety, loads analyses, vibroacoustic test criteria, and pyroshock test criteria. A parallel effort, also funded by the Office of the Chief Engineer, was undertaken by the Jet Propulsion Laboratory and its contractors to summarize and assess mission dynamic environments, state-of-the-art procedures for predicting the dynamic excitations or loads induced by those environments and the structural responses to those excitations, and for establishing dynamics criteria with appropriate margins for the design and testing of a spacecraft and its components, along with the equipment and procedures used for testing. Contributions were made to this handbook by many members of the aerospace dynamics community; those contributions are gratefully acknowledged.
