Hello,
I would like to simulate a mechanism consisting of a pendulum (Point A), a pulley (Point B), and a slider (Point C) in an assembly.
The conditions are:
- The wire between Point A and Point C is inextensible (constant length, no stretch, no slack).
- The wire passes over Point B (pulley).
- The pendulum is rigid one-part.
My questions are:
1. Is it possible to build such an assembly model using relations or other Creo mechanisms?
2. Can this model be used for motion simulation in MDO (Mechanism Dynamics Option)?
I tried using relations based on measured distances (Analysis → Measure).
However, it seems that the measure feature cannot be used on the left-hand side of a relation, so I could not enforce the constraint properly.
Does anyone have suggestions for modeling this kind of system in Creo?
(I am useing Creo11)
Thank you in advance.
