How to make the small ball slide into the groove in Simscape multibody

Click For Summary
SUMMARY

The discussion focuses on resolving a simulation error in Simscape Multibody related to a mechanism involving a small ball sliding into a groove. The error message indicates a "position violation" due to the model not being assembled correctly. Key insights suggest that synchronizing the movements of the disk and lever, both rotationally and linearly, is crucial for successful simulation. The user is advised to consider the initial velocity of the disk as negligible to simplify the problem.

PREREQUISITES
  • Familiarity with Simscape Multibody modeling
  • Understanding of rotational and linear motion synchronization
  • Knowledge of position violation errors in simulation
  • Basic skills in manipulating simulation parameters
NEXT STEPS
  • Research how to resolve position violation errors in Simscape Multibody
  • Learn about synchronizing rotational and linear movements in mechanical systems
  • Explore the effects of initial velocity on simulation outcomes in Simscape
  • Investigate quick return mechanisms and their modeling techniques
USEFUL FOR

Mechanical engineers, simulation specialists, and students working with Simscape Multibody who are troubleshooting simulation errors and optimizing mechanical designs.

TL;DR
I have an issue in making the small ball slide into the groove
Good day All!
I have a problem , I could do almost all the mechanism, my problem is how to make slide the little ball into the groove. whenever i run the program i got the follwing error message
['rotating_groove_cylinder_good_trial']: The following errors were found in the model rotating_groove_cylinder_good_trial.
Caused by:
['rotating_groove_cylinder_good_trial/Solver Configuration']: *** Model not assembled: position violation *** Resolve this issue in order to simulate the model.
the wheel rotates around a fixed hinge.
I have joined the program file,
Many thanks in advance

It seems that the system is asking you to synchronize the movement of the disk and the lever, both rotational and linearly.
That Vo of the center of the disk greatly complicates things in this case, unless its value is small compared to the rotational velocities.

 
Thank you, consider is 0 as the disk is rotating around the center O. how can we solve it?
thank you
 
I don't know how to manipulate any software, sorry for not being able to help more.
I just added a video to my previous post, which shows the close inter-dependence of both members, being this a quick return mechanism.
