Reference points and rigid body

Reference points and rigid body

Reference points and rigid body

(OP)
I want to assign two reference points to a rigid body in Abaqus.
 To assign the first point I used the constraint Rigid body.
 What constrain can I use for the second point?
 I try with coupling constraint, but I think it takes too long   simulation.
 Sorry for my enghish!
 

  

RE: Reference points and rigid body

You can't apply two reference points to a rigid body.

Thats right, You can apply excatly ONE reference point to a specific rigid body.

The article shows in fig 1-3 that each part has one reference point. If each of these is conctrained to move together, then that is a different matter. Use *equation or tie them to link them.

So, every rigid body have a reference point around which rotation is free (RP1-RP5).
Free rotation of the rigid bodies around their own axes.
But, all rigid bodies rotate around the reference point RP6.
