The suspension system of vehicle Formula Student that it must have weight light. The numerical wheels to various parts of the suspension system, and should be a cheap, readily available. Including the wishbone (A-Arm), Hub,Upright, by calculating the force exerted on the part of the driving conditions. The Factor of Safety 2 times, and then analyzed using SolidWorks simulation, each piece will be analyzed from two different material types. Aluminium grade 7075 was Yield strength 435 MPa with iron AISI grade 1020 was Yield strength 351.57 MPa experiments have found that maximum of the throttle in each material is similar material is made from Aluminium7075 will be displacement than iron,aluminum is lighter than the steel weight almost 3 times.
Wishbone front lower building materials, steel AISI1020 could not get the force exerted by Factor of Safety 2 times because of stress, up happening is that the Yield strength of the material, thus changing values. The Factor of Safety 1.5 times, which was the result that the lower wishbone front wheel can withstand up to 1.5 times of the Factor of Safety.
