The following report outlines the full design process that the senior project team went through to develop a steering system for the 2018 Cal Poly Supermileage vehicle from the development to the manufacturing and testing of the senior project steering system. The team was successful in reducing the weight of the steering system from 12.64 to 5.85 pounds while remaining within the cost budget provided for the Cal Poly Supermileage team. The new steering system initially failed drop testing which resulted in the uprights pulling out of the bottom carbon supports. This failure was repaired with a small redesign to the steering system and retested. Testing shows that the steering system will be strong and stiff enough for proper implementation into the 2018 Supermileage vehicle. Learnings from this report will provide the club with valuable information and a prototype steering system to use as a platform to improve and implement in their 2018 competition vehicle.
