FSU-05/07/19 Upper Control Arm Assembly

Model Version: 8.0

Material: AISI 4130 steel, annealed at 865C

Yield Strength: 460 MPa

Validation: June 15th 2023

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

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

  • the Jens method

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

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

• 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

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

Fz:

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