Abstract

A need for a drivetrain and steering system that could provide locomotion and directional control for the H&H RC Baja racecar was needed. The RC Baja event is a competition hosted by the CWU ASME club in which teams of engineering students compete against each other to test the effectiveness of the respective designs. The car needed to be able to compete in three events: a drag race, solemn course, and a Baja event. This was accomplished by designing and manufacturing several parts of different materials utilizing a range of manufacturing techniques to produce sub-assemblies and that made up the drivetrain systems. The system were constructed using a variety of methods including; matching of parts, 3d printing, and off the shelf parts. The RC car was designed in SolidWorks a parametric modeling software to ensure manufactured parts were easy to assemble the systems were designed using; material analysis, statics, and concepts from mechanical design, across 12 unique engineering analysis to guide the engineering decisions and manufacturing processes and ensure the car would meet all requirements set forth by not drivetrain engineer but also the suspension and chassis Engineer The combination of all analysis, decision matrixes, designing, manufacturing and assembly, resulted in a top speed of 25mph was able to climb inclines up to 30 degrees and weighted less than 4 pounds.
