Pictured above is the Front Upper A-Arm assembly, which consists of the A-Arm made from structural steel (Yield point @ 250 MPa), and the three corners of the Front Upper A-Arm are SAKAC 8 M with M8 Nuts installed.
In the finite element method of the Front Upper A-Arm, the applied load is the load if the maximum cornering force and maximum braking force occur simultaneously, according to the table above, and set the mounting point between the A-Arm and the frame to be fixed support and let the load acting on the mounting point between the A-Arm and the knuckle.
