Hello
I have a Catia Assembly, made up of sub-assemblies. Each subset contains its own assembly constraints, kinematic links and the mechanism driving it.
Question: In the main assembly, what tool would simulate all the mechanisms simultaneously or sequentially? We tested the Submechanism Import function, but only the piloted links animate.
Thank you for your help, cdlt
This is a question for the specialist @franck.ceroux
I've been interested in simulating mechanisms in CATIA for a while. So your question is of great interest to me. On the other hand, I don't really understand your question. Can you clarify your question?
1) Do you want to animate your mechanism in ASSEMBLY or DMU Kinematics?
2) Do you have any assembly constraints for the main assembly between the subassemblies?
then other assembly constraints for each of the parts of your subassemblies?
3) Does your mechanism have kinematic loops? If so, it will be necessary to control the right number of degrees of freedom in the system. For example, for a connecting rod-crank system, there will be only one ddl to drive.
See you soon
Yes, the animation is DMU Kinematics and I want to do it at the main assembly level.
Yes, the main assembly has constraints between the subassemblies
Finally, at the level of each subset, I have a Controlled Mechanism (DDL=0).
The idea is therefore to create a link between the sub-assemblies and controlled, with the simultaneous animation of the mechanisms of the sub-assemblies
Hello, sorry but I don't have the KIN license (DMU kinematics).
If you can't find help here maybe on this side

I'm not sure that you can have 2 levels of mechanisms simulated with DMU Kinematics.
By the way, in DMU Kinematics, all the kinematic links that are created are at the same level in the shaft at the mechanism level.
Otherwise, with a 0 ddl system with the controls is what is needed before starting a simulation.
Sorry for not helping you more. Maybe the solution would be to switch to a more powerful tool (tjs with CATIA) namely LMS Virtual Lab. But, you still have to have the license but also to get to grips with it, which is far from easy...
Thin,
If Franck Ceroux dries, it will be complicated.
Notice to his employer: he must be the KIN license (DMU kinematics) the KIN license (DMU kinematics)!
