Gantt Chart
11
Scheduled Goals for This Semester

• Finalize overall design
• Start manufacturing the frame
• Purchase
• Frame Tubing
• Shocks
• Torque Converter

12
Benchmarking

• Optimum wheel base
• best overall length
• 108 is the recommended length

13
Critical Function Prototype (C.F.P.)

• Motivation
• Last years model is tight
• Ergonomic concerns

C.T.F of the Frame
14
C.F.P. Goals

• Find an ergonomic solution
• Visually Stimulating
• Pass all of the SAE rules
• Manufacturability

15
Lessons from C.F.P.

• Cockpit length
• Back rest angle
• Complexity of manufacture

16
Refinement of Design

• Frame (Modify the angle of front control arm and
  shock mount).
• Frame height requires additional 6.

17
Refinement of Design

• Transmission using chain drive between gears.
• Optimize gear span in torque converter.
  (acceleration, low end torque and efficiency)
• Rear control arms (light, strong, adjustable and
  stable)

18
Conclusion

• Many items currently modeled in Solidworks
• Design revisions under way for frame, control
  arms, torque converter
• Benchmarking continues
• On schedule
