Mechanical System

The MIT Solar Electric Vehicle Team continues to develop and improve its mechanical systems with each vehicle. The mechanical system generally consists of the suspension, brakes, chassis, and steering. Design begins with Solidworks, a computer modeling software, where students work in conjunction with the aero team to maximize efficiency. Using a finite element analysis method, students optimize each component, while working under the constraints of rules and the aerodynamic body.

After a few months of deliberation, the team moves forward with a design, jumping straight into construction. All work on the vehicle is done in-house by the students themselves. Most production and all assembly is completed in our shop on campus. Thanks to the generous support of the Institute and the Edgerton Center, SEVT has the resources and space it needs to complete such an extensive project.

 

Chassis:

The chassis is designed to protect the driver from impacts. Valkyrie is the first solar car in SEVT history to have an all-composite chassis. This design has been chosen in preparation for the next four-wheeled vehicle to ultimately achieve flexibility in the chassis design.

Chopper’s chromoly steel chassis is designed to protect the driver from impacts. The two front wheels have dual A-arm suspensions, while the rear wheel is attached with a trailing arm.

 

Suspension:

The two front wheels have dual A-arm suspensions, while the rear wheel is attached with a trailing arm. Each suspension has been improved since the last design with optimal geometry and mechanical parts.
