Project Overview: 2-3 paragraphs that provide a general description of the project – background, motivation, customers, problem you’re trying to solve, project objectives.
BACKGROUND:
Over the past few years, the Hot Wheelz Electric Vehicle Team has been developing various configurations of electric vehicles for Imagine RIT competitions. As the team develops and looks to move into a larger scale competition the project will require more advance testing equipment and a more rigorous design and build than in the previous years.

PROJECT:
The RIT Hot Wheelz Electrical Vehicle team is taking on a large challenge and building their first ever Formula SAE Electric vehicle. There is currently no method to test the electro-mechanical drive system. Due to the scope of the project, the team is in need of a user friendly, size appropriate testing platform. Key electrical drive system performance data, such as torque output and battery life, are required to optimize the system capabilities. Safe operation of the electrical components and smooth integration of the completed drive system onto the chassis of the vehicle are desired as well as the ability to verify the system's compliance to the SAE rules. The project will be constrained by a limited budget, strict timeline and desired size limitations.
Detailed Project Description:
The goal of this section is provide enough detail for faculty to assess whether the proposed project scope and required skills are appropriate for 5th year engineering students working over two quarters. The sequence of the steps listed below may depend on your project, and the process is usually iterative, so feel free to customize. Emphasis is on the “whats” (qualitative and quantitative), not the “hows” (solutions), except for the section on “potential concepts,” which is necessary to assess the appropriateness of required skills and project scope. Not all of the information in this section may be shared with students. (Attach extra documentation as needed).
● Customer Needs and Objectives: Comprehensive list of what the customer/user wants or needs to be able to do in the “voice of the customer,” not in terms of how it might be done; desired attributes of the solution.
1. Ensure Electro-Mechanical drive system safety
2. Acquire Data under various testing conditions( battery life, torque, etc)
3. Produce a series of subsystem manuals for future use.
4. Produce a safety manual and procedures.
5. Features a user friendly control panel and interface.
6. Capable of user variability of applied load on the Electro-Mechanical system
7. Testing unit to fit in the Hot Wheelz Room
8. Incorporates emergency stop/ safety features.
9. Incorporates mechanical safety features to prevent injury to the user.
10. Electro-Mechanical Drive System that mimics placement on the vehicle chassis
11. Monitor testing results during test as well as a data storage method to view and analyze data after the test.
● Functional Decomposition: Functions and sub-functions (verb-noun pairs) that are associated with a system/solution that will satisfy customer needs and objectives. Focus on “what” has to be achieved and not on “how”it is to be achieved – decompose the system only as far as the (sub) functions are solution independent. This can be a simple function list or a diagram (functional diagram, FAST (why-how) diagram, function tree).
o Provide power to the system
o Engineer’s Design Manuals
o Promote the engineering development for future expansion
o Support System components
o Motor load scheme to simulate acceleration, deceleration and dynamic braking
o Data collection and storage for performance monitoring
o Platform to hold all testing components
● Potential Concepts: Generate a short list of potential concepts (solutions) to realize the system and associated functions. This may involve benchmarking or reverse engineering of existing solutions. For each concept and its associated function(s), generate a list of key tasks or skills needed to design and realize the function(s), and identify which disciplines (ME, EE, CE, ISE, …) are likely to be involved in the design and realization of the function(s). See the “PRP_Checklist” document for a list of student skills by department. Potential concepts, skills, and tasks should not be shared with students.
● Fixture that has the ability to vary load to the electro-mechanical system (ME)
● A platform that safely holds all components of the test fixture as well as electro-mechanical system (ME)
● Data collection system to monitor and store output for performance tuning. Could export to a spreadsheet or text file. (EE)
● Electro-Mechanical components of the RIT Hot Wheelz Vehicle that will be undergoing testing. (EE & Hot Wheelz Team)
● System Safety (ME & EE)
● Interface that allows the user to apply loading parameters. Interface would allow for constant and variable loading during the testing.
● Specifications (or Engineering/Functional Requirements): Translates “voice of the customer” into “voice of the engineer.” Specifications describe what the system should (shall) do in language that has engineering formality. Specifications are quantitative and measureable because they must be testable/ verifiable, so they consist of a metric (dimension with units) and a value. We recommend utilizing the aforementioned functional decomposition to identify specifications at the function/ sub-function levels. Target values are adequate at this point – final values will likely be set after students develop concepts and make tradeoffs on the basis of chosen concepts. Consider the following types of specifications:geometry (dimensions, space), kinematics (type & direction of motion), forces, material, signals, safety, ergonomics (comfort, human interface issues), quality, production (waste, factory limitations), assembly, transport/packaging, operations (environmental/noise), maintenance, regulatory (UL, IEEE, FDA, FCC, RIT).
Electrical Specs:
● Max tractive system voltage = 300V(Formula SAE Rules Maximum)
Mechanical Specs:
● Constraints: External factors that, in some way, limit the selection of solution alternatives. They are usually imposed on the design and are not directly related to the functional objectives of the system but apply across the system (eg. cost and schedule constraints). Constraints are often included in the specifications list but they often violate the abstractness property by specifying “how”.
- Formula Hybird 2015 Formula Hybrid Rules (Revision 1 – 9/16/2014) or newer.
- Budget money.
- Limited Space
- Strict Timeline for completion
● Project Deliverables: Expected output, what will be “delivered” – be as specific and thorough as possible.
o Working system that will apply a load on the electro-mechanical system in order to collect data and test different configurations prior to live testing on a chassis.
o Electrical and Mechanical Safety components to prevent system overload or failure
o User friendly interface that acts as data acquisition
o User friendly control panel to define load on electro-mechanical system
o Operation Manual
o Software Manual for Software Libraries developed.
o CAD drawing and simulation of the entire test fixture.
o Schematics, evaluation fixtures and simulations, as appropriate.
● Budget Estimate: Major cost items anticipated.
Item / Approximate CostElectric Motor(s) / $6000
Motor Controller / $10000
Wiring/Electrical Components / $7000
Batteries / $10000
Method to apply load( magnetic brake, electric motor, etc) / $200
Test Bench Components / ~$4000
TOTAL BUDGET / $37,200*
* Overestimated budget, can/will scale back when project parameters are solidified. Electrical budget ($33,000) will be part of the Hot Wheelz Team budget not the sole responsibility of the Senior Design Project
● Intellectual Property (IP) considerations: Describe any IP concerns or limitations associated with the project. Is there patent potential? Will confidentiality of any data or information be required?
● Not sure what we are thinking for this section: need to discuss further
● Other Information: Describe potential benefits and liabilities, known project risks, etc.
Benchmark existing systems from other universities, if possible. Field visit to other development locations.
● Continuation Project Information, if appropriate: Include prior project(s) information, and how prior project(s) relate to the proposed project.
This could potentially be longer than a two term project. We may need assistance figuring out what is feasible within our timeframe.
