Collision issues with custom module imports

[Jay Sun]

Hello everyone,

I was using solidwork to build a custom model, and this problem occurred with the import, Importing custom models in pychrono keeps colliding and won't stop. How do I solve this problem. (video links: https://youtu.be/SeSbmbPPn8E)

The second problem is how to detect the force on each wheel, or the value of the wheel load.

The third question, how to detect the sink of deformable terrain. 

Looking forward to your reply. Thank you very much!!!

Regard,

Jay

Hi Jay,
about collisions: did you went through the documentation about collision settings and tried to tune the parameters before asking on the forum?

about detecting forces: if you are using simple rigid bodies did you went through the documentation about collision callbacks before asking on the forum?

If you will use other specific tire models things are different, but since you are importing from SolidWorks I don't think that it's the case.
I don't know about deformable terrain.

Hi Dario,

Thank you very much for your reply! I read the document you recommended, which explains how to define the collision between two objects by yourself. But I the collision in solidwork import objects (in my here is the car) and deformable surface (pychrono. Vehicle. SCMDeformableTerrain) between. In solidwork, I set the collision boundary according to https://api.projectchrono.org/tutorial_chrono_solidworks_demo_shapes.html, in my case is the wheel. Then it was imported into pychrono and touched with deformable terrain, and the footage from the video appeared. It keeps bouncing, and there seems to be no energy that's not conserved.
