Development Process of a Formula SAE Chassis 2011-32-0656
Chassis design on a racing car must meet many conflicting requirements including high torsional and flexual rigidity, driver safety, optimum suspension geometry, a low center of gravity and light weight. In comparison to our 2010 model, the frame weight of the 2011 model was reduced by 15% whilst increasing torsional rigidity to 920Nm/deg. Suspension geometry was refined based on driver feedback and track chronometry. Suspension components were simplified, reducing weight by 10% and greatly reducing cost. A standardization approach was taken from the 2011 model, allowing a near complete compatibility of commercial parts amongst different year models.
