I started showing two handlebar model versions (before and after 2017 model). Introduced my constraints into the handlebar, fixation and load location. But now what? The objective!!!! I wanted to know where was the weak spot of the handlebar. It has two elbows at each side. Where will the cracks start preferebly? I could just say 50% chance on any of the elbows but that would be to easy.
So why not Build the simulation model???? First check my previous posts:
Handlebar mesh
Forgetting about model accuracy I am just looking for the stress field.
My assumptions:
- Isotropic material
- No transient effects
Making the mesh was straight forward with FreeCAD. The two meshers in FreeCAD behaved differently in Gmsh I could not use the default values. I had to use max 1.8mm and min 0.8mm mesh size. On NetGen I used the default without any issues.
I am not saying that it was easy to setup things… I got many installation issue however in the end everything worked. Fortunatelly FreeCAD has a great forum that can help when in need.
On a next post I will look at the results…
