Disc Rotation
Disc Rotation
(OP)
Hello all,
I have a static twin disc contact model that I am satisfied with. I would now like to develop this model to simulate disc rotation in contact. I have never develop such a model and wondered if anyone could provide some advice on how to go about this?
Many Thanks

RE: Disc Rotation
Thanks for your input, so I could do this by applying a 'Moment' in the loads section? or a rotation in the 'BCs' section of the Step menu?
By setting a coupling constraint what does this mean to the model?
Thanks again, you inout
RE: Disc Rotation
"Boundary conditions are specified on inactive dof of 2817 nodes. The nodes have been identified in node set WarnNodeBCInactiveDof".
Have you comes across this before or know what it is?
RE: Disc Rotation
Basically the coupling will force the coupled nodes to move with the control point in the DOFs specified. In your case probably just rotation.
My guess is that you have rotational DOFs constrained on a symmetry plane. Basically Abaqus just ignores them and issues a warning. In the results there is a node set of these nodes so you can figure out what the problem is.
I hope this helps.
