Project Definition OverviewThis project focuses on the development of a Electric Motor Test Bench for RIT's Electric Vehicle Team. This project is designed to test the capabilities of the motor of an electric vehicle when used in conjunction with a motor control unit. The test bench will apply a dynamically variable load to the motor and controller, and then measure how these components react to the given conditions. REV(05-12-2016)
Overview of StatusA dynamic load test bench was developed and tested. The project was an overall success. A few redundant systems were not able to be completed, and user documentation was not as flushed out due to time constraints caused by budgetary issues.
Customer RequirementsCustomer Requirements were developed from meetings with the EVT team, as well as various "startup packages" from the EVT team.
Engineering SpecificationsEngineering Specifications were developed based off of the results of the Functional Decomposition, as well as from the Customer Requirements.
Achieved SpecificationsThe following are the results of our product compared to the nominal and minimum values determined at the beginning of the project.
TestingSubsystems were individually tested and then integrated. Sensing subsystems are performing as planned, though a smaller range current sensor would be an improvement to the system.
Through sponsorship, our budget expanded significantly. The final Bill of Materials below shows the totals spent for each subsystem. In total almost $26k was fund-raised through the course of this project.
SchedulingThe original plan for MSDII was changed significantly through the course of this semester. Due to major issues with using the donated golf cart motor as a Unit Under Test, the plan ended up behind by 3 weeks by week 8. The team reassessed out schedule at that point, settling on the final schedule shown, and successfully completing the project on time.
The team kept an accurate list of major project problems, which were regularly discussed among the whole team, as well as presented at design reviews. This problem tracking let us each individually deal with problems, while remaining accountable to the team as a whole.
At this time, there are no major problems left to be fixed, as the test bench is in a working state.
- When major budgetary concerns are present, it is most beneficial to front load component decisions to ensure that extended lead times for donated goods will not be an issue
Currently, all soft-copy deliverables have been uploaded to Edge. The following deliverables have been transferred to the customer.
