NASA-HDBK-7008, NASA TECHNICAL HANDBOOK: SPACECRAFT DYNAMIC ENVIRONMENTS TESTING (12-JUN-2014)

NASA-HDBK-7008, NASA TECHNICAL HANDBOOK: SPACECRAFT DYNAMIC ENVIRONMENTS TESTING (12-JUN-2014)., This Handbook is published by the National Aeronautics and Space Administration (NASA) as a guidance document to provide engineering information; lessons learned; possible options to address technical issues; classification of similar items, materials, or processes; interpretative direction and techniques; and any other type of guidance information that may help the Government or its contractors in the design, construction, selection, management, support, or operation of systems, products, processes, or services. This Handbook is approved for use by NASA Headquarters and NASA Centers, including Component Facilities and Technical and Service Support Centers. This Handbook establishes recommended practices across NASA programs, addressing dynamic environments testing of flight spacecraft, large instruments, associated dynamic test models (DTMs), and flight structure subsystems for the mission dynamics environments and loads. The emphasis of this Handbook is on vibration, acoustic, and shock environmental testing. Static and modal testing are discussed only in regard to the role each plays in complementing the dynamic testing in a complete structural qualification program. Recent advances in the areas of structural dynamics, vibrations, and vibroacoustics, in both methodology and capability, have the potential to make spacecraft system testing more effective from technical, cost, schedule, and hardware safety points of view. However, application of these advanced test methods varies widely among the NASA Centers and their contractors. Identification and refinement of the best of these test methodologies and implementation approaches has been an objective of efforts by the Jet Propulsion Laboratory (JPL) on behalf of the NASA Office of the Chief Engineer (OCE). To develop the most appropriate overall test program for a flight project from the selection of advanced methodologies, as well as from conventional test methods, spacecraft project managers and their technical staff need overall guidance and technical rationale. Thus, the OCE has tasked JPL to prepare a NASA Handbook for Spacecraft Dynamic Environments Testing. The Goddard Space Flight Center (GSFC) has agreed to co-author this Handbook.
