  1. AMPHIBIOUS VEHICLE

  2. The Team The Project Overview The Design & Prototype The Testing The Conclusion The Acknowledgements

  3. Michael Gondhi Steve Brink Steve DeMaagd Jasper Gondhi Tyler Vandongen • THE TEAM

  4. THE GOAL Colossians 3:17 “And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus, giving thanks to God the Father through him.”

  5. PRIMARY GOAL Design and develop a working prototype of human powered amphibious vehicle (AV) by applying the principles of an engineering design process from concept to production. THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  6. SECONDARY GOALS Speed on Land of 15 mph Speed on Water of 2 mph Successful Braking on Land Successful Transitions between Land and Water THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  7. Design Goals • Water: • Buoyancy • Stability • Getting on/off • Turning radius Land: • Speed • Braking • Turning radius • Stability THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  8. Design Norms Trust Transparency Stewardship THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  9. Scope Human-poweredrecreation vehicle market Customer: Lake house owners Flood region service Customer: Disaster relief agencies and NGO’s THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  10. THE DESIGN & PROTOTYPE THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  11. FRAME DRIVE TRAIN PROPULSION STEERING FLOTATION THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  12. FRAME THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  13. FRAME – Finite Element Analysis Maximum Deflection: 0.08 in. Direction of Force • MODEL W/ FEA THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  14. DRIVE TRAIN FRONT AXLE PADDLE WHEEL AXLE THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  15. DRIVE TRAIN – FRONT AXLE Minimize Axle Length: 66 in. - 62 in. 0.75 in. 0.475 in. THANK YOU PROJECT OVERVIEW DESIGN & PROTOTYPE TESTING CONCLUSION

  16. DRIVE TRAIN – PADDLE WHEEL AXLE Paddle Wheel Axle Aluminum Tubing Wheels Flotation Initial safety factor used for flotation = 2 Result: Vehicle floats too muchand paddle wheels don’t hit water as they are placed with respect to the flotation Change: Paddle wheel assembly lowered to match necessary height.
