Impact function and contact are not working

Hello everyone,

I would like to simulate a platform sliding on the ground supported by two wheels. Initially, I tried using the contact , but it was not effective, so I replaced it with the impact function

When I disable Joint 6, the results are as expected: after the platform tilts, it slides along the desired road profile.

However, this is not realistic because Joint 6 exists in the actual mechanism. When I enable Joint 6, the platform penetrates into the ground. Could anyone please advise me on how to fix this issue?

Thank you very much.

Hi @tonynguyen_1432,

Does your impact force show any reaction during the simulation?

Is any force generated at all?

Hope this helps!

Hi @tonynguyen_1432,

Based on the constraints in your model, your geometry wont allow that IMPACT force to do much. There is force being generated but the Motions will overpower it. Deactivating Joint 6 allowed the the system to move according to the Motions in your model.

If you turn off Motion 1, the top table Body 0 will slide down and contact the ground (Body 3).

Without Motion 1:

output_motion1_off.mp4

Hope this helps!
