MIL-S-901 Shock testing
(OP)
Does anyone have practical experience in tests acc to MIL-S-901D? (Barge test) I just wonder whart is the practical way of measuring the G levels? Will the instrumentation, cabling, recorder etc. fly all over the place? I know you can experience extreme G-levels.
Thanks for any input.

DTIC has other stuff from him as well as other shock-related documents.

Yes, I have been through Clements. Gives some very good insights to the levels and dynamics. But we may now be at the threshold of doing such a test. And this is probably beyond any shock levels we have been "used to". And the difference between theory and practise.......
But thanks for the input.

If the g-levels inside the insulation go down far enough, you wouldn't need to do anything inside the boxes. Otherwise, you might need to put some sort of foam insulation on the inside of the boxes. You'd also probably need to get solid state drives, of course.
You can probably test your instrumentation ahead of time, by whacking it with a hammer test; you can tune the fixturing to get the comparable levels of shock as the barge.

RE: MIL-S-901 Shock testing
Do accelerometers fall off? Yes, if you use those little accelerometers that you glue on they will sometimes fall off during a shock blow if you have very high G levels. The accelerometers that you mount on a stud are much more robust, but they are bigger and require you drill and tap holes into your UUT.
For more detailed information you can always call one of the test labs.
