Calculating force on isolators under a room

mlarm

Hi, I need to insulate a room built like a box using vibration isolators and need to know the force on top of the isolator pad in order to select the right isolator. I've tried different ways of creating the walls/floor but the results I am getting is all over the place so I am questioning my abilities here ... Is there a tutorial/template or any other example that models a room like below (sketchup example) ? Where should I place the fixed supports? Under every pad or just in the 4 corners of a ground slab?

Hello mlarm

Not sure if I understand quite what you're doing, so here's a picture of my interpretation.

If the ground slab is effectively fixed (very massive and stiff) then you can put fixed supports under each isolator and ignore the ground slab.

What's wrong with the results? Feel free to post a .liml file or email it to me at the support address if you don't want it public.

Tutorial 2.7 "Dynamic Response of a Solid Part" under Help->Tutorials sounds similar.
