  1. Team UDFSAE: Chassis Group Harmon Amakobe, Sharnita James, Stephen Rosenkrantz Faculty Advisor: Dr. Steven Timmins Sponsor: Michael Bauman Overview and Scope Drivetrain, Powertrain Final Design • Split Assembly • Design and fabricate a stiff and lightweight tube-frame chassis • Completely original design with emphasis on: • Weight loss • Split-chassis design • Sub-system integration • Aesthetic appeal • Constraints • Compliance with 2014 FSAE rules • Design and fabricate drivetrain mounting • Design and fabricate engine mounts • Design for exhaust and intake clearances • Design for appropriate chain clearances • ½” Bolts in double shear • Extra long weld and gusset areas designed to strengthen joint • Sleeved for compressive strength Manufacturing • Tube prep • Rough cut with miter saw • Final cut on lathe • Bend tube if necessary • Notch on lathe with hole saw • Polish and clean tube for welding • Tack structure together • Assembly • Tack subassemblies together • Double-check manufactured tolerances • Final weld (TIG) Final Drivetrain Design Weight Loss 2012-2013 Chassis • Cost • Key Metrics • 71 lbs • Thin wall (0.028”) tubing • Strategically placed nodes • Chain tensioned by turnbuckles • Turnbuckles in tension • Pivots about bottom pinned joint • Factor of Safety of 4 • Clearances optimized using CAD • Large, heavy • 115 lbs • Extra nodes, thick tubing
