10/08 Fergo Meeting

SRR Discussion

Overall Comments

• Utilize hand-calculations and intuition prior to running FEA (i.e. FEA is a validation tool, not a tool start a design)

• Starting a welding training schedule

  • Would it be useful/do y’all want to start delving into that this semester or save it for next semester?

Ergo SRR specifics

• Carbon Fiber is not the most viable material in terms of cost and usability for ergo

  • (i.e Fiberglass is cheaper and just a usable for the steering wheel, CF maybe uncomfortable for seat)

  • Need to really reflect on how it will be used/if it will be worth the cost

• Ergo Jig is a good idea → need to further reflect on how we collect driver data/bounding box limits

  • We need to set a clear data gathering methodology to make sure data is consistent and accurate

  • Also may need to go more in-depth into leg length and torso height, rather than just “height”

• Need a way to test egress before building the car

• Need a way of measuring the average braking force of our drivers, relative to adrenaline

Frame SRR specifics

• Setting up a proper composite chassis research proposal

  • I.e. having a clear theory/goal, prior research as to why we want to pursue it, plan as how we want to manufacture and test composites, etc.

• Beam elements absolutely must be used in for FEA simulations

  • Simulations have no need to take hours of load time, focus on beam elements, quick iteration time, etc.

• Need to set a date/plan on finalizing a roll cage design/dimension soon

  • This is a huge blocker for aeroshell, we need to get this done so they can progress

• When planning out bounding boxes/references for frame sketch, make them into solid bodies

  • Ensures you don’t accidentally go out of bounds without noticing

Workday Plans

Ergo:

• Continue working on pedal box redesigns for Daybreak, have some sort of tangible results/prototypes soon

• Finalize ergo jig plans, come up with materials budget

• Compile and create sizing plan for ergo driver model and bounding box

• Materials research?

Frame:

• Continue compiling dimensions and dependency values (suspension hardpoints, length and width, roll cage dimensions, etc.)

• Discuss and finalize architecture selection (multi level frame, 3-wheel car frame design, etc.)

• Assign research tasks to members on composites research and solids hand calculations

• Plan out design task breakdown (how are we splitting up frame jig, frame design, etc.)
