SAE Baja Frame Design Brandt Lamonte, Luke Blocker, Alexandria Williams, Kyle Richert Advisor: Ho-Hoon Lee

SAE Baja Competition ▶ Intercollegiate design competition by Society of Automotive Engineers (SAE) ▶ Challenge is to build a small vehicle that can withstand harsh terrain ▶ Build must follow certain rules and guidelines set forth by SAE (Size, Capability, Human Factors, etc. ) Frame Construction and Material 4130 Tubular space frame with 1020 steel brackets and tabs Joining method and material GTAW ER 70 -S 2 filler Targets (Torsional Stiffness or other) 2000 lbs-ft/deg (2712 N-m/deg) Torsional stiffness and validation method 2100 lbs-ft/deg (2847 N-m/deg) CAE beam model, 1800 lbs-ft/deg (2440 N-m/deg) physical test Bare frame weight with brackets and paint 55 lbs (25 kg)

Our Project ▶ Team consists of 9 members, split into 4 different design groups (Frame, Suspension, Steering, Power) ▶ Our group will focus on the design of the frame. ▶ Group will be split into 2 subgroups to provide 2 individual frame designs ▶ Complete Solidworks 3 D design with stress analysis

Purpose The project will: ▶ Demonstrate the students’ ability to research, plan, and orchestrate the designing of a frame with given parameters ▶ Give the opportunity for M. E. T. students to apply knowledge in a real-world assignment ▶ Test the students’ ability to work within a group and communicate clearly, concisely, and professionally ▶ Create a well designed and efficiently built Baja buggy frame

Method (Brandt & Luke) ▶ Research to gain understanding ▶ Decide desirable tubing size ▶ Make reasonable assumptions to begin modeling ▶ Stress analysis ▶ Select material and estimate cost ▶ Mesh frame concept with other groups’ component designs ▶ Design mounting interfaces ▶ Final stress analysis ▶ Final modifications

Deliverables (Brandt & Luke) ▶ Solidworks 3 -D frame design ▶ Complete stress analysis of frame ▶ Design of mounting interfaces between Baja team groups ▶ Material Selection ▶ Cost analysis

Tentative Timeline (Brandt & Luke) February 24 th Proposal presentation Brandt & Luke February 25 th - March 10 th Research and initial design Brandt & Luke March 11 th - 17 th Design alongside Suspension team and adjustments Brandt & Luke March 18 th - March 31 st Research and rough draft Design Brandt & Luke April 1 st - April 7 th Stress Analysis Luke April 8 th - April 15 th Develop 3 D Model of final draft in Solidworks Brandt & Luke April 16 th - April 21 st Design mounting interface Brandt April 22 nd - April 23 rd Material selection Luke April 24 th - April 27 th Cost Analysis Brandt April 28 th - May 4 th Create final proposal and presentation Brandt & Luke May 5 th Present final presentation Brandt & Luke

Method (Alex & Kyle) ▶ Estimate respectable dimensions for ▶ driver’s comfort ▶ placement of suspension ▶ configuration of powertrain ▶ steering components ▶ Research materials ▶ tensile strength ▶ round and square tubing ▶ weight ▶ machinability ▶ Design 3 -D model using Solidwork or Comsol with force analysis ▶ Cost analysis

Deliverables ▶ (Alex & Kyle) Research a metal material that complies with the SAE Mini Baja regulations ▶ (Alex) Provide accommodations for other Baja components (powertrain, suspension, and steering) ▶ (Kyle) Understand how to create using reverse engineering ▶ (Alex & Kyle) Create 3 D model analyzing forces and complete stress analysis ▶ (Kyle) Cost analysis

Tentative Timeline (Alex and Kyle) February 7 -23 Meet with advisor, group selection, create proposal and presentation February 24 Presentation Day February 25 -March 10 Research and rough draft Design March 11 -17 Design alongside other teams and adjustments March 18 - April 7 Develop 3 D Model of rough draft in Solid works or Comsol April 8 - 21 Develop 3 D Model of final draft in Solid works or Comsol April 22 -May 4 Create final proposal and presentation May 5 Present final presentation
