Hello @Anonymous ,
You have a contact issue and you needs to make some other changes.
1. Contact between the Binder Base + Support and the efficentfloor. The Activation Distance can be calculated from SQRT(mesh size ^2 + distance^2) = SQRT(0.1^2+0.136^2) = 0.33 in.
2. I would add a solver contact > bonded type, because you are missing contacts between the other parts and the Binder Base + Support.
3. This solver contact doesn't create a contact between multi bodies. Binder Base + Support is a made up of 3 Solid Bodies. Use the Combine feature to combine them to one single body.
4. I added an extra Mesh refinement (0.15 in) to part Circle Cover v2.4 L:1 because of meshing issues.
5. I changed the time step size to 0.00004 sec (1/(100* dominant frequency).
Below an animation of the result.
For some reason I can't attach a simple zip file with a size of 4 MB to this post, so you can download your modified model here. (The link is valid until June, 4th, 2021).
Instead of Structural Damping I would suggest Rayleigh Damping. Take a look at this post.
