Chassis Overhaul
Problem statement
The University of Wisconsin – Madison Formula SAE Team requires a new chassis for their electric and internal combustion racecars to meet the competition rules and make strides in vehicle weight and stiffness. The previous chassis designs have added many “band-aid” fixes that make it difficult to pass the competition’s technical inspection and add unnecessary weight to the vehicle. A ground-up redesign is needed to easily and efficiently meet the rules. The overhaul includes the creation of completely new composite panel design and monocoque geometry. The suspension is also designed around a new tire, and changes the actuation from a corner damper system to a roll-heave damper system. The co-designing of the two projects allows for a better overall vehicle chassis design, and permits the team to incorporate design changes that would be difficult without coordinating the changes to the monocoque and suspension. Although the scope of the project introduces the risk that the team would be unable to compete if the project were not completed, similar projects have been undertaken at competitor teams such as Cornell Racing, at Cornell University. Their reports allow for a deeper understanding of the undertaking. Creating Formula SAE cars is an educational experience that allows students to gain unrivaled hands-on engineering experience. Working with the team to redesign the chassis will allow them to compete and reap the rewards of their hard work.
