Fixtures

Fixed on hub nut’s inner threads

Loading

Applying +Fx only on the portion of hub nut that contacts the rim

Mesh Settings

  • Using curvature-based mesh

  • Applying mesh refinement to the flange edge (max node size of 2.67 mm)

  • Using h-adaptive method with mesh coarsening enabled

Mesh Convergence

Material yield strength: 460 MPa

Brake + Right Turn

  • Most positive Fx load case

  • Max stress not converging, but stays within a small range << material yield strength → PASS

Recommendations

Could add a fillet on the boss edge to reduce the stress concentration there, as seen in the above loading cases.
