Abstract
This was our 2017 Senior Design Project.
Goal: Design an ergonomic chassis weighing 50 lbs (~22.7 kg) that complies with FSAE rules, and maintains a torsional stiffness of at least 700 ft-lbs/deg (~950 N*m/deg). The resulting stiffness-to-weight ratio shall not be lower than 14 ft*lbf/deg/lbs (~41.8 N*m/deg/kg).

Material selection: 4130 Chromoly tubing
Cockpit design: material sizing matrix
Impact attenuator material selection: 3003 Aluminum Honeycomb
Impact attenuator design options: Rectangular block yielded best results overall.
