Team Vision for Problem Definition PhaseSummarize: 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.
- Why does the customer need this?
- What are the customer requirements?
- What existing devices can begin to solve the problem?
- What are the engineering requirements, based on the customer requirements?
- What kind of intellectual property do we expect to
- How do we intend on sharing the IP among ourselves and with the RIT Baja Team?
- What kind of risks do we expect to have to mitigate in this project?
The team has actually accomplished the following:
- Defined the customer's desires for the device.
- Defined the engineering requirements for the device.
- Done a little research into existing solutions.
- Defined the intellectual property allocation of the project.
- Defined what risks we expect to face and their
- Began defining methods of mitigation
Project SummaryThe 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.
