Abstract

The engineers at Central Washington University were each asked to produce a device to compete in the ASME RC Baja competition. The principle-engineer set out to create a system that allowed an RC car to be controllable over a variety of terrain utilizing suspension and steering principles. The steering and suspension designed by the engineer was implemented in part with a drive train and chassis that was designed by a partner engineer.

The Engineer chose to utilize an independent front suspension with a solid rear axle for his design. This design was chosen because the independent front end allowed for the front to stay very stable and the trailing arms in the rear allowed for the car to have a lot of suspension travel and suspension flex. This proposal covers the design, manufacturing, and testing of the device throughout the fall, winter, and spring quarter.

The device was completed at the end of the winter quarter and testing began at the beginning of the spring quarter. The testing results showed that the device met some key requirements, the suspension deflection was 3” after a 3’ drop and the steering angle met the 50-degree requirement. The device performed well and met the engineer’s requirements stated in section 1.d of the proposal.
