Team Vision for Problem Definition Phase

Summarize: The team planned to define the challenge posed by this project. The following steps will be used to define the problem before moving on to developing an action plan.

The team has actually accomplished the following:

Project Summary

The RIT Baja team currently lacks a method of determining the capacity of the driveline to efficiently transmit torque to the wheels. The Baja drivetrain engineers require a metric to quantitatively measure the efficiency of several half-shaft designs, specifically CV and U-Joints, so that they can use verifiable test results to make a more informed engineering decision as to which half-shaft design to use.

The goals of this project are to design a test apparatus for the Baja team to use in their shop to measure the applied and transmitted torque through a variety of half-shaft designs, to do so through the entire range of the outboard hub travel, and to convey this information to the user to allow for the power loss comparison of different designs.

Use Cases

The following document defines the expected use case for the driveshaft efficiency tester.
