i’m an idiot i should have done the maximum tensile case of bwd left acceleration. lmk if these sims look ok and i’ll come back to do that load case! Jens Dekker

Mesh settings:
Using curvature-based mesh
Applying mesh refinement to the flange edge
Using h-adaptive method with mesh coarsening enabled
Mesh Convergence
Material yield strength: 460 MPa
Fwd left acceleration
Maximum stress is like one high stress node on the edge between the flange and the nut boss
Nominal forces on the hub nut body appear to be converging to around 0.035 MPa, but then drops to 0.012 MPa at the smallest tested node size
Max Node Size (mm) | Mesh Picture | Max Stress (MPa) | Nominal Stress (MPa) | Location/Results |
|---|---|---|---|---|
5.63 2.67 (on flange edge) |     | 7.146 | 0.02862 |    |
4.53 2.67 (on flange edge) |     | 7.683 | 0.02972 |    |
3.57 2.67 (on flange edge) |     | 11.15 | 0.03499 |    |
3.01 2.67 (on flange edge) |     | 16.38 | 0.0352 |   |
2.57 1.66 (on flange edge) |     | 54.57 | 0.01217 |   |
Bwd right acceleration
Nominal forces on the hub nut body appear to be converging-ish around 0.0125 MPa
Max stress 29.47 MPa < 460 MPa → PASS
Max Node Size (mm) | Mesh Pictures, after h-adaptive refinement | Max Stress (MPa) | Nominal Stress (MPa) | Location/Results |
