I am trying to study a design for a non-pneumatic wheel.
The problem is the part is very complex. The flexible supports are made from layers of thin aluminum sheet metal strips. The double whammy , the mesh is very fine to correctly map the thin sheet metal & I have about 54 non-penetrating contacts in-between the layers of sheet metal.
The contacts would behave similar to this
The non -penetrating contracts are there because the sheet metal is set up similar to a leaf spring . Another issue is I can't find a way to simplify the wheel. I can't run a 2-d simulation because the part is not symmetric throughout . I have tried using shells for the sheet metal but I also have solid parts. I would have to learn how to do a hybrid study.
I have run the entire wheel in a static study & the deformation looks appropriate but I know it needs to be analyzed with a non-linear study to be accurate.
I have a decent computer that maxes out around 7,000,000 nodes, but this non-linear study is taking forever.
any suggestions on how to simplify this part? Thank you
