Design and Test Criteria for Components Subjected to Explosive Shock Environments 690616

Full scale ground tests of explosive separation of missile stages defined the shock environment for sensitive components, and indicated the requirement for specification of test criteria according to component weight or location. Design and qualification test criteria for the components were derived by enveloping the peaks of ensembles of shock test response spectra. This approach was justified by analytical considerations. The resulting test criteria specified response spectra tolerance limits of + 100% and − 50%, and a damping ratio of 0.05 (Q = 10) for the shock response spectra analyses. A shock synthesizer electrodynamic shaker system was used successfully to conduct shock qualification tests using the criteria developed for the separation shock environment.
