This year the team goals were reduce energy loss with a stiffer vehicle, update the car to fit competition requirements, and find replacement tires for the car. It was the hope of the team to produce a reliable car that could be worked on easily.
The braking system had to be adjusted from previous years due to the new competition requirement of including hydraulic brakes and a pedal brake for the front wheels. Our design’s simplicity allows for future capstone teams to easily adjust the braking system if necessary.
A new alignment tool was designed to improve accuracy and reduce time to set up the car. It works by measuring the length between the front and back of the two front wheels and moving them until they are equal. This measurement must be precise because the wheels are cambered. The wheel camber makes it so that the distance between the front and back of the wheels must be measured at the same height (relative to the ground).
Due to the old wheels not being manufactured any more new wheels were found. This was done by a series of tests. The image above shows a spin-down test to determine the time decay of a set of bearings that are equipped to the vehicle. This test was similarly developed to help the team compare the friction losses in a set of bearings and determine which bearings would perform best during the competition.
