Presentation on theme: "Ergonomics & Driver Controls"— Presentation transcript:
1 Ergonomics & Driver Controls David Anlian, Justin Greenidge & Alan RadojcicProblem BackgroundFormula SAE is an international collegiate engineering design competition which challenges universities to design, manufacture, and race formula cars. The premise of the competition is to create a marketable race car for the average weekend racer.Final AssemblyShifting SystemThe main focus for the design of the mechanical shifting linkage are reliability, weight, and comfort. Some key design aspects include:Designed weight is 3.5 lbs. versus a 6 lbs. linkage in the 2013 racecarCan withstand a force of 250 lbs.Project ScopeThe FSAE Ergonomics and Driver Controls team is responsible for the complete design and manufacturing of all subsystems of which the driver is in direct contact. This includes:Pedal boxSeatShifting SystemSteering SystemDashboardFuel TankDashboardKey Design AspectsCarbon Fiber constructionTachometer in direct view while drivingAim MXLPista Data Acquisition SystemSteering SystemThe 2014 FSAE Steering Assembly is designed to be stiff, aesthetically pleasing, and lightweight. Through careful material selection and geometric design, this year’s steering assembly outperforms any previous year’s design. Low deformation and flex with in components (0.01 cm < )New single U-Joint connection design (25% more precise)Minimal slop design (< 0.01 cm within system)1 lb. lighter than 2013 designPedal BoxThe 2014 FSAE Pedal Box is designed to be lightweight, durable, ergonomic, aesthetically pleasing, and easy to assemble and disassemble.Extremely stiff with a high factor of safety (3.0 and up)4 lbs. lighter than 2013 designFuel TankThe main focus for the fuel tank were weight and volume. Some key design aspects include:Use of .05” thick 5052 Aluminum Alloy for corrosion protection and minimal weightA designed weight of 5 lbs. when compared to the 10.5 lbs. tank built in 2013SeatKey Design AspectsSeatback angle of 50° from horizontalDurable and lightweight carbon fiber constructionAcknowledgementsWe would like to thank the following individuals for their immense efforts in advisement and resource assistance for the engineering and manufacturing tasks undertaken this semester:Dr. Steven TimminsFrank SneeringerSteve BeardJeff RickettsDave FogartyRob BuchlerAdrian Sawyer
