99 Teams Attended
Suspension & Chassis Team• All new suspension geometry & components• New optimized chassis tailored to the suspension points
Drive-train Team• New dual reduction gearbox with Forward-Neutral-Reverse & inboard brakes• Custom CVT system-Senior Design Project• New drive shafts
Composites Team• Continued development of composite manufacturing techniques• Front & rear upper suspension links• Steering post holder• Front lower suspension arms
Flotation & Propulsion• Flotation for the 2009-10 vehicle• New adjustable fender
Data Acquisition System• Stand alone data acquisition unit• Strain gauges, accelerometers, temperature sensors, etc.
Dry weight < 375 lbs◦ 15% reduction from 2009◦ Smaller and more robust chassis◦ Improve FEA to optimize components
Acceleration Time < 4.8 seconds◦ Reduce vehicle weight & reduce rotational mass◦ New gearbox: improve efficiency◦ New CVT: improve efficiency and greater shift range
Develop Data Acquisition System◦ Record “road load” data◦ Benchmark vehicle design and compare simulations◦ Use data to create accurate simulations in the future
February 20, 2010 at Lake Linden Community ParkEstimated Attendance: 60 vehicles - 25 Universities
4 Hours of Endurance Competition
