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

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

 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

 Original  Final Design

Manufactured at CSUS, by FSAE team

 A - Arms

 Bearing Holder  Hub & Spindle  Upright

 Camber  Caster  Wheelbase  Track Width

 Rate of camber angle change per degree body roll

 Rate of camber angle change per inch of wheel displacement

 Strain Gages

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

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

 Elastic

 Rosette location  Probe

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

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