Week 4

Week 4

During week 4, the team designed the Pedal Box in Solidworks.  The entire assembly will be made from various thicknesses of 6061-T6 Aluminum.  This material was chosen for its strength to weight ratio.  A few members performed a Finite Element Analysis of each part using Solidworks' built in features.  As stated in the Formula SAE rulebook, the brake pedal assembly must be able to withstand an applied force of 450 lbs. Every part had a safety factor above 1.5, which was the minimum value expected by the advisors.  The maximum displacement under that maximum load was 0.0328" which is well under the maximum values stated in the FSAE rules of 0.125".  Solidworks calculated the total mass of the assembly to be 8.79lbs.
