Wheel Hub FEA Report - 05/29/23

Fixtures

Had bearing support fixtures to act like the bearing that connect the hub to the spindle and used roller sliders on the bearing to hub connection faces as I think they have the ability to slide when in rotation, can be removed if needed (JENS ROAST ME PLS).

Recommendations

Reduce mass on the back part of the hub that is in contact with the spindle, potential chamfer would be nice.
