Even if you can't answer my question, maybe you can direct me to a forum that can.
I am attempting to design/make a vibrating platform (think foot massager) that has the following characteristics:
1. Vibrates at a frequency between 12-25 Hertz
2. Has an amplitude (displacement) of less than 4mm. Ideally somewhere between 1-4 mm.
3. Has an acceleration of less than 1G. Ideally between .3G's and 1G.
In a perfect world, this platform would only vibrate up and down and not side to side. But as I read more, it sounds like it may have to do both.
I'v done as much research as I can regarding linear resonance actuators, however these all seem to have higher frequencies than what I'm looking for. I then researched linear solenoids, but these seem to have lower frequencies than what I'm looking for.
I'm not sure if a piezoelectric motor would work, but they seem to vibrate a pretty high frequencies also. I vibrating ERM motor may also work but I'm having difficulty finding one that fits my characteristics.
I would greatly appreciate any advice or feedback on if this is possible.
