rotating problem in marc-mentat

rotating problem in marc-mentat

(OP)
Hallo everybody,
I have simulation of rotation disk under contact with a conveyer bell with Marc-mentat. But I dont'n know how to apply the rotation to the disk. If anyone has examples for the rotating disk or similarity problem, please show me how to find it or the links to .
Thanks in advance

RE: rotating problem in marc-mentat

For rotating disks use a point mass with rotational degrees of freedom and tie that to adjacent points at the centre of the disk. Constrain the disk translationally and in 2 of the rotational freedoms. In the rotational direction of the spinning disk apply a known rotational velocity to the mass, or a fixed angular displacemnt. The tied points of the disk will be a rigid region, in effect, so results won't be any use near there.

An alternative is not to impose a rotation on the disk but instead drive the conveyor with a known velocty or displacement. The contact, and friction, with the pinned disk will spin it.
