Bearing Support/Restraint
Bearing Support/Restraint
(OP)
For a 3D structure supported by bearings, which is the best way to restrain the structure at the bearing?
A point support at the centre-line bearing position gives infinite stresses which affects the results close by. This is ok for stresses away from the restraint but at positions close to the bearing I want to know the cummulative effect of the nominal stresses and the bearing stresses. Additional translational restraints at the bearing would give a rotational restraint, which wouldn't be right.
Can the stiffness of the bearing be incorporated somehow?

This looks like it allows for a load transfer into a surface. The points all move together in an average sense, but are allowed to move.
Look in the interaction module under constraints for the coupled constraint. In there, you will see a choice for distributed coupling - the alternative, and default, is kinematic which looks to be the same as rigid MPC's.

"distributed coupling" is not new in 6.4; it's been around for a few releases.
