Design Motivation:

Motivation of Problem Workspace:

For the 2021 fall semester, the Formula Hybrid senior design team is seeking to complete the major outstanding senior level engineering and design work started by the Lafayette Motorsports project after the 2018 competition. This year the structure of the Lafayette motorsports project has evolved such that there is a new performance based motorsports club responsible for getting the current car design to a competition of the clubs choosing while the senior design team will serve as a research and design group for the club. In the initial year of this new structure, the senior design group is working to update documentation, complete outstanding engineering design work, and get subsystems into a working space where club members are able to integrate subsystems onto the car. The senior design team is focusing on completing senior level engineering in the fall semester in order to support the club in their endeavor of competing in competition in their inaugural year.

 

The functional goals and motivation of the Senior Design Team and Lafayette Motorsports club will diverge in Spring of 2022

In the 2022 spring semester, once subsystems have passed off to the club, the Formula Hybrid senior design team will commence design work for selected subsystems for the 2022-2023 car in order to give the Lafayette Motorsports club completed designs/prototypes in order to improve performance of the car for the following year.

 

Synthesized Literature Review:

The working subsystems— Chassis, SCADA, Suspension, Cooling, Steering, Battery Packs, Drivetrain, and CarMan, CellMan have each preformed a literature review and identified a problem space that requires senior level engineering and design throughout the fall semester.

Stakeholders:

For this project, identified stakeholders who would benefit from the completed formula hybrid car would include the Lafayette College Enrollment Division, Lafayette Motorsports club, the audience of the formula hybrid competition. These stake holders directly benefit from the completed project such that they would gain greater understanding of a disciplined engineering design process, inspiration to pursue potential careers in STEM, or in the case of admissions would be able to more directly market the benefits of Engineering at Lafayette College. Additionally, if the Formula Hybrid project pushes the “state of the art” in any technical area of research then the list of stakeholders grow to include specific researchers in fields of note such as data acquisition, electric vehicle dynamics, fuel efficiency, or structural integrity, etc. Of particular note, if successful, this project can have significant ramifications in increasing fuel efficiency for electric vehicles and for inspiring new generations of traditionally under represented groups to become involved in engineering.

Subsystem Goals:

Each working subsystem has identified major goals for their respective subsystems. A brief overview of these goals can be found here.

Budget & Schedule:

The senior design team has generated a high level overview showing interdependencies between subsystems in order to accomplish our long term goal of delivering subsystems to the Lafayette Motorsports club by the end of the semester. Additionally, our team has generated internal Gannt charts (Mechanical & Electrical) that are available for viewing. The team has also developed a high level overview of our proposed budget for the year. For more information click here.

Team Structure:

In order to accomplish our chosen goals the senior design team has created a management hierarchy that can be explained in detail here.

Safety Plan:

To aid in our initial explorations and problem scoping of the project the senior design team has developed an initial safety plan to allow/disallow entry into AEC 134, where the majority of the mechanical work for the car takes place. For more information on this safety plan see here. Safety plans will be updated to include additional precautions as use of energized tools, electrical equipment, etc become necessary.
