Assembly

JL82

Are there a connector on Mecway? I have the simple assembly and you can see it in the attachments.

I want to add a joints at the ends oft the tension rod. How I add the joint?

Hello JL82. You can do it using *RIGID BODY like this:

• Change Analysis settings -> Solver to CCX.
  
• Add a node on the axis of the pin.
  
• Create 2 node selections for the 3 hole surfaces.
  
• Add a CCX -> custom model definition containing 2 *RIGID BODY cards that use the new node as the REF NODE.
  

I've made one pin like this on the attached model.

Caveats are:

• The hole surfaces become rigid.
  
• It's really a ball-joint, not a pin-joint. so you may need additional constraints or constraint equations if you want to enforce that.
  
• The moment arm along the length of the pin is neglected. In this case, it doesn't matter because of the symmetry, but if you were connecting only two plates instead of a symmetric three, it could be a problem.
  

An unrelated suggestion is turn on Fit midside nodes to geometry in the Meshing parameters for all the parts and remesh. That will make the holes circular instead of faceted.
