  2. Outline • Executive Summary (TT) • Design Approach – HOQ (PM) • Design Approach – Block Diagram (KL) • Material Selection (PM) • Frame Design Optimization (KL) • Finite Element Analysis (FEA) (KK) • Timeline – AIL (AL) • Resources Needed (SB) • Summary (AL)

  3. Executive Summary • Project Background • Building an off road vehicle to SAE specs, with intent to sell to general public • International competition of 100+ schools • Problem Statement: Previous frame designs have been overbuilt with material that was too thick, or supported with unnecessary members adding extra weight. • Goals: • Focus efforts on weight reduction of 100 pounds. • Can be achieved through applying principles of material selection, frame design optimization, and Finite Element Analysis (FEA)

  4. Executive Summary • Team Responsibilities: • Material Selection (PM) • Frame Design Optimization (KL, SB, TT) • FEA (AL, KK) • Bottom Line • The overall project is estimated to cost approximately $855. The project will begin on January 14, 2014, and will be completed by March 7, 2014.

  7. Material Selection [1] 4130 (Chromoly) Normalized Alloy Steel 4130 Chromoly • The material selected for the use of this years SAE baja frame will be 4130 “chromoly” steel. Although it is more expensive than typical 1018 steel, the durability, ease of welding, and superior strength to weight ration makes it a prime material for off-road applications. A majority of other teams use this material and have had great success in past competitions.

  8. Design Optimization • Tube frame chassis: Rear Roll Hoop (RRH) Front End Base

  9. Design Optimization: Side View Template

  10. Design Optimization: Auxiliary View

  11. Finite Element Analysis (FEA) • Performing static representation of dynamic loading to find failure modes of frame • Models followed from other teams/auto industry • Goals are to locate areas of minimum stress and reduce member size • Top, front, side impacts, roll over

  12. Time Line

  13. AIL

  14. Resources Needed

  15. Summary • Considering our material selection, design optimization, and use of FEA will allow us to reduce the weight of the frame. • Our goal is to start on January 14thand finish on March 7, and we will achieve this by sticking to our timeline.
