Abstract

An RC car needed to be created to meet set requirements to compete in the annual American Society of Mechanical Engineers RC Baja Competition. Students of the Mechanical Engineering Department of Central Washington University developed an RC car that has working suspension/ chassis size to hold a all components of a working RC car with a floating rear end. This RC car needed to meet set requirements to compete in the annual American Society of Mechanical Engineers RC Baja Competition. The requirements relative to the suspension/chassis is that the RC car must not exceed a weight of 10lb, must not exceed 500 dollars in cost, survive a 1.5ft drop landing flat, and withstand a 506.72N force on the front end during the impact test. To achieve these requirements the team completed material matrices, 24 analysis calculations, and worked together to create a device that achieved both partners parameters. The devices main assembly was broken into sub-assemblies that required parts to be machined using processes such as milling, drilling, and plasma cutting. The principal engineer and Bill Hedlund combined all completed sub-assemblies to finalize the RC Car. After completing construction, tests were completed to decide if the car was ready to compete in the event. After completing the tests, results showed that the car has not exceeded a 10lb max weight, the total cost of the project is 418 dollars, the car sustained the 1.5ft drop and impact of 506.72N tests without the suspension deflecting .5 inches.
