Abstract

The project's primary aim is to employ engineering techniques in the design and construction of an RC Baja car, ensuring the chassis and drivetrain are sufficient for participation in the ASME RC Baja competition. The suspension and steering system were entrusted to a teammate to contribute to the project's success.

In approaching this problem, various analyses were conducted during fall quarter, in deciding the design of the RC car. For example, one analysis established the necessary output power to attain a maximum speed of 25 miles per hour within a 15-second timeframe. The analysis employed acceleration and power equations to arrive at its conclusions. The outcome of the analysis indicates that a minimum of 67.45 Watts of power is essential to achieve the required acceleration. Utilizing a decision matrix helped determine Aluminum 6061 T6 as the material to be used for the chassis. Aluminum is relatively easy to machine, allowing for intricate designs and precise fabrication of chassis components. With this selection complete, the manufacturing and assembling of the RC car took place during the winter quarter.

During spring quarter, The RC car achieved a speed of 20 mph within 25 ft from a complete stop on a concrete surface. Also, the RC car weighed less than 15 pounds fully assembled.

Keywords: RC Baja, Aluminum, Analysis.
