tongue's modelling
Altair EmployeeHi everibody!
I'm doing a project for university. I'm trying to analyze a wheels set connected by a tongue but i'm struggling a lot with the facial contact between shaft and tongue and and also tongue and wheel. For first i tried applying 'freeze' on every face but it doesn't gives good results so i tried with another configuration but i have convergence's problems. What can i do?
I can share the file for more information.
Thanks to all!!!!

Which solver are you working with?
For first i tried applying 'freeze' on every face but it doesn't gives good results
Can you please explain?
yes, please share the model files and also results from Freeze contact.

In this pic ishared an example extracted by my model, here you can see where i freeze the surface between shaft and tongue (B) and also where i do the same thing for tongue and wheel (A). The simulation with this configuration converged and i obtain results.

howevere preview model gives these results, but in my opinion they are wrong cause they are symmetrical.

What i want to obtain is something like this, with asymmetrical stresses congruent with the rotation
About the simulation that doesn't converge i tried freezing only few side of the tongue like in the pic that follows
Unfortunately the model doesn't converge and i don't know how to fix it
I'm going to sent you the model.
I state that i have to do a static analysis of the gearbox.
Hi Lorenzo Loscalzo,
Can you explain little more with some snapshots.
Also, please share your file.
