Hello,
I have a question about assembly constraints and mechanisms.
I am developing a machine which can be simplified as an assembly like A.asm, composed by two main subassemblies:
- B (main part)
- C, which is an optional part to be mounted on B
Part G (external part) is assembled with two given distances from two given axes of B.
B can change its own geometry (E can rotate around a pin of D), thus dragging the part G together in the rotation.
My problem is the assembly of C. C is made with two bars (F and H) pinned in one hole, and is mounted on B so that C rotates together with E.
But, at the same time, I would like to have left hole of H to keep a constant distance from axis of G during the rotation of E.
I tried to accomplish this by:
- setting a constraint inside C with external reference, but in this case the whole A cannot move anymore (error message "mechanism cannot be satisfied anymore"),
- setting a cam constraint between left hole of H and axis of G, but the hole surface is not considered by the software.
Anyone tried something similar and can suggest how to fix this?
I enclose the model in the attachments.
thanks
