Formula Sae Hybrid Carbon Fiber Monocoque / Steel Tube Frame Chassis, Matthew Hagan, John Rappolt, John Waldrop

Mechanical Engineering

The Cal Poly Formula SAE Team created this project in order to design and fabricate a high-performance chassis which would be competitive at 2013 FSAE Lincoln, and to document the process so that future teams could more easily create a chassis. One of the main goals was to reduce weight from the 143- lb 2012 chassis subsystem. A weight of 95 lb was achieved, with 82 lb in the chassis structure itself and a predicted torsional stiffness of 1700 lb*ft/deg. Composite materials design and manufacturing techniques were developed during the project. Design, testing, and manufacturing processes are detailed, and results …

The purpose of this project was to design a suspension that would improve the performance of the Cal Poly SAE Formula Electric car around a racing track Performance would be quantified through skidpad, slalom, and straight-line acceleration tests as well as autocross lap times. The approach to meeting the objective was to increase the steady-state lateral acceleration and quicken the transient response while maintaining predictable handling so that the driver could extract maximum performance from the car.

The car uses round-section (motorcycle) tires at a large negative camber angle because the lateral force generated by a pair of negatively-cambered tires …
