Hi 彰悟 花村

In the initial step create General contact (Standard) interaction between the beam and the tires.

Thank you very much for your reply. I tried as you told me. But it didn't work. The error "General contact surface can not have surfaces defined with edges of shell, membrane, or rigid element." Was displayed.

Hi 彰悟 花村

I meant edge-to-surface contact formulation (something like in the figure).

I'm sorry, but I can't understand what you're saying because of my lack of understanding. I would appreciate it if you could teach me a little more carefully.

I have attached a cae file to this message. I would be happy if you could confirm it.

Now I can't upgrade my Abaqus/CAE to your version 6.21-6. Can you upload .inp file.

I can do it.

Model your tire as a 3-D cylindrical rigid body rather than circular plate.

I modeled the tire as a 3D cylindrical rigid body. But it didn't work. "795 secondary nodes for surface pair (assembly_cp-2-beam-1, assembly_cp-2-wheel-1) are reverted back to type node-to-surface. This case may happen if type surface-to-surface cannot find some nodes Some of reasons are: the secondary is coarser or larger than the main surface, the secondary is not flat relative to the main surface, or secondary nodes that are beyond the extent of the main surface. These nodes have been included. The warning message "in a node set small sliding_ntos_assembly_cp-2-beam-1_assembly_cp-2-wheel-1." Was displayed.

I have an .inp file attached.

The tire model as a 3D cylindrical rigid body is right. In the initial step, you should create General contact (Standard) interaction between the beam and the tire (not surface-to-surface contact).

I have created General contact (Standard) interaction. But it didn't work.

Try refining the mesh on the cylindrical contact surface. Begin with static simulation (horizontal displacement and vertical load). Inp file will be required as usual.

Should I do a static analysis with the tire on the left edge of the beam?

Yes, you can position the tire on the left edge of the beam. The main goal is to establish the right contact interaction.
