Students designed and manufactured an RC Baja car to compete in the ASME RC Baja competition. The goal of this section of the project was to create a steering system and suspension system that work together properly with a partner’s chassis/drive train systems during tests and competitions. The car needed to be able to complete in the three events, which are a drag race, a solemn course, and the Baja event. The RC will also be evaluated on the ability to climb inclines, top speed, and withstand the drop test. This proposal will explain all the details and effort that went into the design and manufacture process that made the steering and Suspension section of this project. Requirements were decided for both portions of this device to help determine what the RC car should look like and how it should operate to be successful in competition. Design used of statics, mechanical design, and dynamics. The design of these systems was accomplished using the 3D modeling program SolidWorks and calculations on green sheets. These two systems were manufactured by methods including machining, 3D printing, and buying parts. Machined parts were made using the Bridgeport but also the lathe and CNC mill. These processes have resulted in an RC car that is able to withstand and not bottom out from drop of 3’, the battery was able to operate for 30 minutes at a time without being charged, and was able to operate from a distance of 10ft away.
