Model Version: 8.09.2 with the Weld Bead Configuration

Material: AISI 4130 steel, annealed at 865C

Yield Strength: 460 MPa

Validation: June 19th 20th 2023

• On Cylindrical Faces radial fixtures on the bearing wall (both bearings)

(Pic)

Note: there are “dummy screws” inserted to simulate the potential interactions between the UCA parts and the screws

Image Added

• Cylindrical faces axial fixture for the screw holes on the bearing housings (both sides)

Image Added

• Virtual wall fixture on inside of bearing (both bearings)

Image Removed

• Local Contact interaction between the screw head and the countersink on the bearing cap (both caps and all screws)

Image Removed

• Bonded component interactions on the UCA plate, Bearing adapters, and Bearing Housing

  • I imagine these pieces will be welded together or something like that - MP

  • Remember to remove the global bond at the start of the sim as not every part is bonded

• Virtual wall on bearing adapters (Top and bottom)

Fx & Fy:

• Fx and Fy are first combined into a single force using trigonometry to determine the magnitude and angle the force acts at, called Fxy

  • Smile Khatri has a good example in their UCA report from the week of may 29th

• Fxy applied at the inside of the UCA Bearing Adapter part, normal to a plane that is at the angle of the applied force

  • The force is only applied to one half of the cylindrical face

    • this is an older version in the picture but it is the same for every version

Fz:

• Applied normal to the UCA Bearing Adapter part, on the side in which the direction of the force is acting

Loading Cases

Any section in Red is greater than the Yield Strength (460 MPa)

The part will always be oriented to show the point of max stress
