Steering Arm FEA Setup and Results

Model found in GrabCAD\MSXIV\Development\Dynamics\Suspension\Edward's Parts - “Assem1 for sim”.

Setup:

  • Fixtures: 2 fixed faces, and two fixed hinges (at UCA and LCA attachment points).

  • 2 bolt connections with no pre-load torque.

  • Force along the direction specified earlier.

Overview of setup.

Two fixed faces.

Two fixed hinges.

Contact set and bolt connections.

  • 2.73MPa is the max force experience, which is a little less than a SF of 2 with the yield strength of 7071 aluminum at 5MPa.

  • The result is most likely surface level forces, so this condition is acceptable.
