Abstract

Students of Central Washington University’s Mechanical Engineering technology program were tasked with designing, manufacturing, and testing a remote-controlled scale vehicle for the American Society of Mechanical Engineers (ASME) Radio-Controlled (RC) Baja Car Contest sanctioned by Remotely Operated Auto Racers (ROAR). A team of three students was assembled and responsibility over the sections of the RC vehicle were divided amongst the three students. This report focuses on the design, manufacture, testing, and evaluation of the suspension and transmission systems of the RC vehicle. A suspension tower component and transmission housing assembly were conceived to satisfy the RC suspension and transmission systems. Engineering analyses were conducted on various aspects of the then to-be-manufactured parts to achieve optimal dimensions. The parts were 3D-modeled using SolidWorks software, and were manufactured using 3D printing methods and machining methods. The various parts were then tested and evaluated to ensure they satisfied their basic requirements and met the criteria of the ASME Contest. The suspension towers and transmission covers conceived in this project are interchangeable, require less than three tools to disassemble, and are able to be assembled and disassembled in less than five minutes. The transmission covers and suspension towers successfully completed a one-hour continuous operation test without any disassembly or reduction in function. The covers also successfully withstood the required exterior forces specified in the report. Both components resisted a drop from two feet, along with the entire RC vehicle.
