2013 NDSU Hybrid FSAE car
Our main goal is to compete with the hybrid car in the 2013 SAE competition. In order to accomplish that this semester, we plan on completing four major tasks. Those tasks are designing the frame, fabricating the frame, integrating the electrical system and the gas system, and assembling all components in the new frame. If these tasks are finished the next senior design team should have enough time to familiarize themselves with the car, test and optimize components in the new frame, and prepare for competition in the spring.
We will begin by designing the frame. This will involve precise planning and measurements for the placement of the component mounts inside the frame. This is important because a low center of gravity is needed in order to increase traction and handling capabilities. Also, the car must pass a static tilt test requiring that the major components contribute to a low center of gravity (Formula Hybrid Rules, 2012). The frame needs to be designed to handle the increase weight of the electrical components and to protect the batteries for safety (Formula Hybrid Rules, 2012). After that we need to fabricate the frame, requiring the bending, cutting, and welding the steel tubing together.
The next task is integrating the electrical system and the gas system, which will be worked on at the same time as designing the frame. For the electrical system we have a 30 ft-lb motor that will run in parallel with a 30 hp gas engine. Both of these drive components will be connected to the differential assembly developed last semester and geared so that the operating range of both components allows for ease of driving and high performance.
Finally, the components need to be assembled in the new frame. This task cannot be started until the new frame is designed and fabricated. Once the design is finished and the frame is fabricated, all the components will be mounted in the new frame and reconnected. Upon completion of this task, testing and optimization of the drive system can begin.
