Coil Spring Force Application Area on Rubber Insulator/Isolator
Coil Spring Force Application Area on Rubber Insulator/Isolator
(OP)
Okay, this is probably just a geometry problem, but I can't wrap my head around it.
If I have a coil spring sitting on an isolator pad the surface of the spring which makes contact with the isolator pad will increase as the force on the spring is increased and the rubber compresses and deforms around the spring end. I would like to predict how much the isolator will bulge out radially, based on the force applied, but I am hung up on the first statement. How can I determine the deformation/deflection of the rubber isolator given a certain spring (and spring force) and applied load to the spring?
Thanks,
Jeff

To be honest I've never worked on the isolator side of this arrangement, we typically modify the spring profile, a non linear FEA seems like a modern approach. We did it on a rig.

What did we do before FEA? Oh yeah...build, test and break, build, test and break...sigh...
