  1. Design Review

  2. Funding: • Remaining items: • Drivetrain • Services • Seating • Steering • $3,250 – Private donations • $1,866 – Funds through SIUC • $1,300- Account balance • Estimate an additional $1,500 needed to complete project

  3. Projects Completed • Suspension: Done except for rocker arms • Frame: Tacked • Driveshafts: Preliminary machining done • Locking mechanism: Assembled • Much of the components have been sent out to be laser cut • Steering, drivetrain, suspension, hinge & lock, etc.

  4. Steering

  5. Steering • Bump Steer • Causes poor control • Result of steering and suspension geometry

  6. Steering • Ackerman: Geometry set up to reduce tires from scrubbing in corners

  7. Drivetrain Two speed HammerSchmidt transmission Intermediate shaft Locking differential U-joint and splined shaft assembly Chromoly axle Heavy duty wheels and tires

  8. Seating • Tubular chromoly frame • Extends above head to provide rollover protection • Folds • Fiberglass seat bottom and back • Contoured to support body

  9. Prepared Questions • 1. Do you have any suggestions on how we can raise additional funding to complete the 2013 SIUC Moonbuggy? • 2. What methods should be used to test safety critical and low factor of safety parts before assembly? • 3. Do you have any ideas on methods to test the completed vehicle to ensure that it is ready for competition? • 4. What suggestions do you have on the material selection and design for the seats? Are there any concerns with using fiberglass? • 5. Are there any other manufacturing methods that we should consider that would decrease our manufacturing time and costs? • 6. Do you have any particular concerns with current 2013 design that we need to remedy?
