Component SRS Testing
Component SRS Testing
(OP)
Certain electronic components must be subjected to shock response spectrum testing, particular if the component must survive a pyrotechnic shock event while in service. (Refer to MIL-STD-1540, 810, etc.)
I have an idea for a new type of shock test machine:
http://www.vibrationdata.com/iv_rod.pdf
One of the advantages of this method is that it lends itself to mathematical calculations (in contrast to most SRS test methods which are black-magic).
I currently do not have the resources to actually build this machine. But a simple, subscale prototype would be easy to build and test.
Anyway, I am available to collarborate with anyone who wants to develop this machine. This project could readily result in a conference paper, and hopefully a commercially practical test machine.

RE: Component SRS Testing
I gave a quick run-through of your paper. I'm assuming you want to build the machine off of the design concept presented in the paper, although more detailed of course. I can design the machine on Solidworks (even test it if necessary) and have a machine shop build the precision parts if needed. I have experience in acoustics and structural dynamics as well.
Go through my website below to get a hold of me if you would like to have further discussion.

It looks simple, but other than orientation and energy source, how is this different from a Hopkinson bar test? Sandia has done a lot of work using them for pyroshock simulation.

This idea is not ready for SolidWorks. It first needs to be tried out using a subscale prototype made from hardware store parts. Thanks for your offer of help anyway.
Jim,
This idea is very similar to a Hopinkson's bar. The excitation source is different as you noted.
One of the ideas of this project is to compare the responses from force excitation versus initial velocity excitation of the bar/rod/pipe/beam.
My career opportunities have taken me away from hands-on testing to straight analysis (for better or worse), so I do not have ready access to data acquistion systems, accelerometers, etc.
But this would make a great science project for someone, as I mentioned previously.
