The Spindle

Model Version: 10.0

Material: AISI 4130 steel, annealed at 865C

Yield Strength: 460 MPa

Validation: July 24th 2023

Fixtures

  • Remove the automatically created global bonded interaction and replace it with a component contact interaction

  • Fully fix the top and bottom faces of the dummy upright

Loading

Fx

  • + Fx acts on the inner face of the thread

    • -Fx is ignored

Fy & Fz:

  • Fy and Fz are combined into their resultant force and the angle that force acts in is found using trig

 

SET ALL FORCES TO “TOTAL” AND NOT “PER ITEM”
