2024-09-30 Mechanical Meeting

Announcements

• Action items I set from last week’s meeting:

  • Have week-by-week timelines in the daybreak gantt chart

  • Have material ready to set a track width, wheelbase, and CoG location

  • Have draft research proposal by EOD 9/28 - Advait

  • Create a more detailed plan (roughly in general detail, doesn’t have to be hyper-specific) for onboarding over the next 5 weeks

• SRR is THIS SUNDAY starting @ 12pm

  • trial run for dynamics, aeroshell, and emech is on Friday evening

What is something you struggled with this week? What is something you are proud of this week?

• SRR Deadlines

• Plan for workday was good and people liked it (even though one person felt like it was a bit repatatvie)

•  finishing all our work

• workday wasnt planned out as well as we wanted

• still proud of how we managed to get people involved

Workday Review

everyone seems to be engaged

got feedback form our form from one person saying that it was interesting and engaging and another person said it was repetitive and a boring presentation what an asshole

• aerodynamics didnt have as clear of an outline as it should have for the first half of the day

• composites was maybe too technical and we’re not sure all the members understood everything

Next Workday Plan

Suspension:

Steerin: Draw the bicycle model for using the previous cars dimensions in solidworks, correlate model with ackerman calculations and correlate ackerman angles with physical steering geometry (4 bar probably, maybe 6 bar)

Unsprun: Spend 3 hours on just going through unsprung together dimensions and finding out all the dependencies. Then go about who needs to do what design.

Aerodynamics:

• Keep building up solidworks knowledge, at least half the day spent teaching them how to do 3D parts, refining splines and relations(give them different parts to make on their own)

• Give them timeline for making the shell, design constraints and everything, find something they can do that helps forward the shell design w/o solidworks, maybe aerodynamics research?

Composites:

• continue research

• kevlar battery box layup

Daybreak Progress?

nun.

N/A

Questions subsystems want to ask:

can one of my members work w composites as a main task this sem? @advait

at some point can we / do we want to do a mech joint lecture practice on FEA on a part or some shit - maybe noah led or smth

same for master modeling from esther perhaps?
