Hi @ahmedhussain18. Thank you for having a look at my simulations. I’m currently doing several various setups, linear and nonlinear, with different geometries. I will be deleting some of the projects, because I’m starting to loose myself between them and some are meaningless. I was struggling to make the assembly simulation actually work, to get it finished successfully.
I found, that it’s best to turn OFF the tolerance for the Sliding Contact. For nonlinear simulations I now use only Absolute option for Convergence criteria type, and using 32-32 computing cores.
I now moved to assembly versions where the left and right side of upright arm are connect by wheel axle. It’s amazing how this connection stiffens entire assembly.
I prepared assembly with coil-end contact-area extruded from the support plate, to have precise area for placing the correct spring stiffness force. The result is very interesting, assembly is very slightly stressed.
And I’m comparing it to another assembly where pivot shafts are mimicked by extruded cylinders to provide surface that is against the mating hole surface (that was at time when I thought the two surfaces in SimScale Contact must be have their normals against each other). And this version gives quite different stress distribution
No pivot shafts, just very distant Sliding Contacts.
Pivot shafts mimicked by extruded cylinder surfaces to face the pivot hole surfaces.
