1. Team Members: Jarret Vian Bryan Rowley John Murray ME 191 Final Presentation Spring 2009

2.  Introduction  Re-Design  Manufacturing  Testing  Conclusion

4.  Minimum 60” wheel base  Unequal front & rear track widths  Minimum 1” ground clearance  Minimum 2” total suspension travel  Template must pass through frame  Spherical bearings must be in double shear  Design must handle applied loading  Rate of camber angle change with respect to both body roll and wheel displacement

5.  Original  Final Design

6. Manufactured at CSUS, by FSAE team

7.  A - Arms

8.  Bearing Holder  Hub & Spindle  Upright

9.  Camber  Caster  Wheelbase  Track Width

10.  Rate of camber angle change per degree body roll

11.  Rate of camber angle change per inch of wheel displacement

12.  Strain Gages

13.  Degrease  Abrade  Burnish  Condition  Neutralize  M-Bond 200  Solder  Connect to instrumentation

14.  Apply the load, and maintain a constant force on the tire  139lbs, 300lbs, 400lbs  Read the strain from each channel on the instrumentation

16.  Elastic

17.  Rosette location  Probe

18.  Assumption: rigid  Assumption: smooth  S y = 50,800psi

19.  Strain gauge and accelerometer data logged during driving  Mychron 3 data logger with internal Accelerometer  Strain gauges
