Upper Control Arm

The Upper Control arm (UCA) is one of the links between the chassis and the upright. It is built using steel tubes welded to a main block. The UCA also includes three Super-Swivel Ball Joint rod ends, weldable tube ends and a jam nut.

Finite Element Analysis

Test Conditions

At the front of the UCA, we applied the reaction loads as the car experiences bump, brake and turn. These load calculations can be seen here:

Calculations

We also applied fixtures at the two rear ends. This is the section of the control arm that mounts to the chassis.

Result

As with all our design, we aim for a FOS of at least 1.4. This FEA study shows a that the minimum FOS of the design is ~6.5 and the nominal FOS is ~19. These are great results. The design passes!!!
