Considering friction between two RBE 2 elements

Hello guys,

 

I need to set up a model just consisting of RBE 2 and BEAM elements to get the reaction and grid point forces in the bearings using Sol 101.

 

I should also consider the the friction caused by the bearings at the representing nodes.

Has anybody some experience how to consider bearing friction in a simple RBE / BEAM model?

 

I am thankfull for every hint.

 

Regards,

 

Georg

Hi GStrickner,

 

I know Gap element can specify friction coefficient in tranverse direction in Sol106. In Sol101 however, Gap element is treated as linear spring element.. not sure whether it helps..

Hi Tuw,

thank you for your reply. Unfortunately in this case the RBEs are representing a joint in that friction should be considerd.

If somebody needs this in future, here my actual solution for it:

I solved it for now in the way, that I applied a moment at the joint node. Therefore you need to know the resultant reaction force in the joint. Out of this and the friction coefficient I calculated the friction moment. To get more accurate results several iterations would be neccesary to edit the reaction moment.
