Wheel Tester

Created on 25 Oct 2019

We are developing a partially-automated wheel tester with built-in data analytics to test wheel quality.

We are developing a partially-automated wheel tester with built-in data analytics to test wheel quality. Factors we will be testing may include rolling resistance, heat dissipated due to friction, time/distance rolled out, speed, and acceleration. The general design idea for the tester is to have a central motor rotate, causing the wheel on an axle attached to the motor to roll out in a circle. We are also considering building a starting "ramp", with an automated brake holds the wheel in place and then releases it, starting a timer and causing it to roll down the ramp and build up speed that way.
