GT Off Road is a club at Georgia Institute of Technology in which students design and build a single-seat off-road vehicle to compete in Baja SAE competitions.

​

Chassis

The chassis is built with a steel tube frame and steel plate mounts. It must integrate all the components of the vehicle while holding the driver safely and comfortably.

​

The chassis is designed in Solidworks and analyzed using Ansys. In addition, RAMSIS ergonomic software was used with NASA anthropometric data. RAMSIS is able to evaluate driver clearances, comfort, and the amount of force a driver is able to tolerate comfortably. Each iteration of the chassis was evaluated to ensure driver comfort.

​

The chassis and mounts were then welded in-house. Therefore, design for manufacturability and jigging were essential. After the chassis was fully welded, it was validated using a torsional stiffness test to ensure it could withstand operational forces.

​

Livery

The body panels are made of vinyl-wrapped carbon fiber and Kevlar. The carbon fiber lay-ups were done entirely in-house. The vinyl design was made to emulate NASCAR liveries in the blue and gold color scheme of Georgia Tech.
