A combined magnetostrictive/piezo electric driver using 2 frequencies works
well for this as well mixing BTW. Wilcoxin makes those drivers for dynamic
shakers and I have one setup in the lab. A large shaker table works really
well but they are heavy and expensive to move around. I've never seen one
with explosion proof electrics either so a barrier would be required.
My guess is you don't have access to equipment like that but they do make
some relatively inexpensive air driven, ball or piston type vibrators that
you can attach to a container directly. They also make tables that have them
integrated. The tables float on air cushions. You can change the pressure to
the motor and cushions to achieve the frequency and displacement you desire.
An accelerometer and a scope to read it is nice to have as well.
That being said, it's easy to end up with solid loading gradients if you
don't characterize the process right.
Good luck.

Subject: [AR] Vibratory compaction
Anyone have experience w/ vibratory compaction if solid rocket propellant,
with or without vacuum?
Initial search did not turn up anything specific....
