rolling shaft model in solidworks

[lucamaria]

Hi,
I have to analyze the deformation on a rolling shaft mounted on two bearings. I m using solidworks and I don t know how I have to fix the constrains. Untill now I tried to use the bearing connector, but there is a convergence error, so the only solution that gives me some result s using fixed geometry for the surface of the two bearings. I would like to find a solution for the same problem also for Comsol to run a dynamic analysis.
Thanks Luca

For shafts it's typical to just simply support the shaft at the centre of the bearings. You don't have to model contact with the bearings

only an edge constraint might lead to inaccurate stress results - numerical singularities.
