Using contact to simulate flexible media between to rigids. How?
Using contact to simulate flexible media between to rigids. How?
(OP)
this fell on me as an urgent task.
ANSYS Mechanical v. 12.1
I've got a long metal spiral pipe covered by a thick layer of "rubber". As pipe deforms (Thermal loads. This I did.) this thing first touch a rigid wall and then rubber deforms.
I want to setup a linear force vs. distance between pipe and the rigid wall to represent rubber compression.
How to do it?
I tried a spring, but it's attached to points, so when pipe merely slides along a wall a force occures. I need forse as a function of distance between a wall and a pipe - not between particular points.
Is there a way to setup some contact boundary condition to simulate this?
I will greatly appreciate any help. This is an urgent and important for me.
Please, be specific about all selections and options as I'm no expert in Ansys.
Thank you
P.S. same post starting with " does not show up when I'm logged out. That's probably the reson for 0 replies. So I repost. Thanks!

If you do need springs then use COMBIN14 as kan123 mentioned, and set it to act only in the direction normal to the wall. You also need to use the ILENGTH feature of this element (Keyopt(3)=1) to define the initial force-free length which in your case is the initial contact clearance.

Can this be done in workbench?
