  1. Mini Baja

  2. Mini Baja goals • Modular suspension • Concept • Analysis • Rebuild of rear frame • Automated transmission • Air shifting system • Implementation of electronics

  3. Modular suspension • Bolt on hoop design • Symmetric about the center of car • Installation in less then 20 min

  4. Analysis on suspension • Deflection testing • Finite element analysis • Bolt selection

  5. Frame changes • Narrow the frame to account for added hoops • Add brake to center shaft • Create space for air components

  6. Air shifting system • Air compressor • CFM • Battery • Air tank • Size • Weight • Cylinders • Shifting • Clutch

  7. T.C.M. – “daughter board” • Sensor Signal Preparation • User Input Recognition • Output Signal Conditioning • Upgrade Ready Design Circuit boards provided by PCB Fab Express

  8. Modern Device’s Arduino Clone • Self-Contained Microcontroller Main Board • C++ Derived Programming Code • 10 bit Analog to Digital Converter • 14 Digital Input / Output Pins • 6 Analog Input pins

  9. Conclusion

  10. Conclusion continued • Suspension operated as expected • Air components shifted transmission in manual testing • Electronics had errors and failed upon initial testing • Causes of failure are: • Electro-Static Discharge • Unforeseen components needed

  11. Questions ???????
