Disclosed are a method and apparatus for simulating pyrotechnic shock for the purpose of qualifying electronic components for use in weapons, satellite, and aerospace applications. According to the invention, a single resonant bar fixture has an adjustable resonant frequency in order to exhibit a desired shock response spectrum upon mechanical impact. The invention eliminates the need for availability of a large number of different fixtures, capable of exhibiting a range of shock response characteristics, in favor of a single tunable system. 32 figs.

Pyroshock simulation for satellite components using a tunable resonant fixture

Conference - in OSTI.gov collection Davie, N.T. ; Bateman, V.I.

Aerospace components are often subjected to pyroshock events during flight and deployment, and must be qualified to this frequently severe environment. Laboratory simulation of pyroshock using a mechanically excited resonant fixture, has gained favor at Sandia for testing small (<8 inch cube) satellite and weapon components. With this method, each different shock environment required a different resonant fixture that was designed such that it's response retched the environment A new test method has been developed which eliminates the need to have a different resonant fixture for each test requirement This is accomplished by means of a tunable resonant fixture thatmore »« less
