> There was a need to test the relative energy consumption of different rim, tube, tire, pressure, and hub configurations.
> Working with a computer engineering student, I designed a bicycle wheel dynamometer.
> Adaptable to fit any wheel and tire size.
> Can be used to measure relative energy consumption, or provide a constant wheel speed for other testing.
> Uses a bicycle computer, rotary encoder, and a microcontroller to measure, control, and report wheel speed, flywheel speed, and time.
> Currently in validation stage:
Further testing is required to ensure accuracy.
> A snow-bike trail groomer was designed in the fall of 2016 for a local trail system.
> I am the current project lead of this project. The original designer has graduated.
> Design includes multiple implements that can be attached to a chassis that is pulled by a snowmobile.
> Current implements include a plow and a grader.
> Future implements include a snow compactor and a snow tiller.
> Additionally, we working with the customer to determine required design changes to current system.
