Abstract

The RC Baja team set out to engineer and construct a working remote-control device that can compete in the ASME Baja Competition. The students have a focus on either suspension and steering or drivetrain and chassis. This report is centered on the suspension and steering. First, multiple analyses were completed using engineering methods such as mechanical design, statics, strengths of materials, and dynamics for parts of the device. The calculations found in the analysis are then used to create designs for the parts so that they will meet the requirements and be successful in the competition. After the parts are designed, they are then constructed using multiple methods of manufacturing such as machining, 3D printing, or a type of outsourcing. The parts are then assembled into a working device. The device is then tested to those set requirements and finally, compete against the other devices in the competition. The device withstood the testing with having under a 7.62 mm deflection on the lower control arms with a static loading of 9.1 kg. The suspension was able to travel well over 60 mm, the device had the ability to corner at 5 m/s without rolling, and the device was able withstand 3 vertical drop tests from a height of 650 mm. The device also placed in the top 5 in each discipline in the ASME competition.
