Spring element between solids

Spring element between solids

Spring element between solids

(OP)
Hello guys!
I'm trying to model some solids elements connected with ONE spring CBUSH element and I have rigid motion problems :(
Do you have any idea, how to eliminate this problem without modelling couple of spring elements?
P.S. I've constrained the rotational dof of the CBUSH, but I'm still getting rigid motion.

RE: Spring element between solids

3D element nodes do not have rotational stiffness.

what you could do is use RBEs to connect the CBUSH nodes to several nodes of the solids (so that the moment in the CBUSH is distributed to several nodes, as couples).

another day in paradise, or is paradise one day closer ?

Thanks rb1957! I played a little bit with the RBEs. From the one side I created RBE2, so it will deform as a rigid body and to the other side RBE3, so the load would be uniformly distributed.

White Paper - Considerations for choosing a 3D printing technology
The adoption of 3D printing into major companies’ product development life cycles is a testament to the technology’s incredible benefits to consumers, designers, engineers and manufacturers. While traditional production methods have limitations in manufacturability, 3D printing provides unparalleled design freedom due to the additive method of building parts layer by layer. Download Now
