  6. 6. Senior Project 2 Gantt Chart<br />
  7. 7. Modified frame design from <br /> mock up due to the rider position<br />Ordering a 20” solid front fork with <br /> disc brake mounts<br />Will weld mounts for other front brake<br />Begin manufacturing <br /> steering assembly<br />Rider Position and Steering<br />
  8. 8. Frame <br />James VanBiervliet<br />
  9. 9. Frame<br />A full scale model was created from wood<br />
  10. 10. Frame<br />Using the finalized dimensions obtained from model, a roll bar was designed<br />
  11. 11. Frame<br />The frame was then broken down into elements and nodes<br />
  12. 12. Frame<br />Pieces of bamboo were then cut according to the list of elements<br />
  13. 13. Drivetrain & Frame Integrations<br /> Dante Mucaro<br />
  14. 14. Drivetrain Revisions<br />Gearing<br />50-34T crankset replaced in favor of 50-36-22T triple ring crankset<br />10spd 11-28T cassette replaced with 9spd 11-34T cassette<br />Crank arm design modified to collar-type adjustable crank mount<br />
  15. 15. Table of Gear Ratios<br />
  16. 16. Comparison<br />27 available speeds vs. previous 20 speeds<br />Broader range of gearing<br />“Granny” gear equivalent speed decreased ~40%<br />Top gear equivalent speed increased ~13.5%<br />Negligible cost impact<br />
  17. 17. Twin Disc Front Hub<br />Twin disc mounts for standard 6-bolt rotors<br />Machined from 6061 aluminum stock<br />
  18. 18. Current Drivetrain Status <br />Components ordered<br />Cassette, crankset, bottom brackets, single sprockets, chain, derailleur (F&R), rims & spokes, brake rotors & calipers, shifters, cables<br />Front hub and wheel construction<br />To be completed by March 8<br />Crank arm implementation<br />To be integrated into frame structure prior to frame completion<br />Rear dropout fabrication<br />Design to be finalized and implemented prior to frame completion<br />
  19. 19. Aerodynamic Fairing<br />Rich Nelson<br />
  20. 20. Design and construct, <br /> respective of constraints,<br /> a single-rider recumbent fully faired human<br /> powered vehicle. <br />Compete and win the 2010 ASME East Human Powered Vehicle Challenge. <br />Aerodynamic Fairing - CFD<br />Velocity Contour Plot<br />Pressure Streamlines<br />
  21. 21. Aerodynamic Fairing - CFD<br />#1<br />#2<br />#3<br />
  22. 22. Aerodynamic Fairing – Plug Construction<br />Took cross sections from CAD model <br />Made wooden cross sectional templates<br />
  23. 23. Aerodynamic Fairing – Plug Construction<br />Using wood templates to shape foam into plug<br />Next – Sand plug smooth, prepare for Vacuum Bagging<br />
  24. 24. Aerodynamic Fairing – Fabrication<br />Vacuum bag layup of both halves of Fairing<br />Cut out top hatch of fairing and wheel cutouts<br />Integrate fairing into the frame and fiberglass halves together<br />
