2024-12-02 Mechanical Meeting

Announcements

• LHR OB elections this Wednesday at 7PM in ECJ 1.202

  • at least 50% of leadership from each team must be present

Highlights

really cool solar car we found(matthew & jason) i think we gotta pivot the design

Aeroshell had the highest attendance out of any system this workday, both in number and percent (2/20 attended) (this includes leads and members)

Blockers/Conflicts

Do you have any blockers or conflicts that are preventing you from making forward progress/completing certain tasks OR making things more difficult than they should be?

no more china

Review of Thanksgiving Break

What was planned for break:

What got done:

Try to get CAD for the each part of the car done for each subsystem

Aerodynamics

• have finalized vague architecture design?

Advait - Finish daybreak stuff + finish battery box panels + finish processing for initial test of first forged carbon fiber test, figure out what to improve in manufacturing/prep process

Continue work on designing/planning ergo projects

Finalize ansys setups for frame sims

• motor controller cooling

• Intake/exhaust panel patterns

• Parthiv got a haircut

Steering got upper and lower steering CAD to exist

Unsprung was traveling the entire time

Suspension got a mix of some CAD and force matrix but also some weren’t able to get work done.

Overall minimal progress but people were able to rest

Aerodynamics

• some members(at least 2) got their sims done

Composites

• all bb layups except 1

• all daybreak prep done, pretty much ready to bond w/ frame whenever

• Did first frame test pieces

• Did one with a higher vol fraction which looks better (bc less excess resin) but i forgot to take pic

• Sanded the fcf part a bit, not effective. takeaway: we need to get rid of layer lines in mold. solution, more sanding or acetone

  

• michael and i cleaned out pickle

Ansys sims for latest frame iteration was setup and ran

Only of a little bit of progress on daybreak pedal box, otherwise not much ergo work done

• motor controller cooling

• Intake/exhaust panel patterns

Plan for this week - please break tasks down into sub-tasks

Dynamics

• CAD for every part should exist by Thursday

Unsprung

• Sim the hubs.

  • redisign

Steering

• Talk to Kenta about actual location of upper steering pertaining to steering wheel

• Fix the steering in the frame reference sketch

Supension

• completely define the hdpts

• first sim dummy apexes and bellcranks

• define spring rates ( have to talk to ic and fix some orientations of the masses on the car maybe)

• probably going to tweak the motion ratio in the front - first shock selections

Aerodynamics

• everyone needs to have an idea for the part they want to put on the shell, it needs to be able to put together as a final part on workday

Aeroshell(me)

• need to define some architecture things by workday, flat topshell or not,

Composites

• finish battery box, another metal sheet to be sanded, start making test coupons for nomex honeycomb frame panels, finalize test fixtures for panels, finalize test plans for demold and resin infusion

• Also will be working w/ emech to finalize plans for composite enclosure and also testing abs acetone vapor stuff to use in composite enclosure and composite steering wheel

Frame

• Compile all data from latest sims → see what design changes to make from there

• Continue jig design and weld plan → set due December 14th

Ergo

• Review initial designs for ballast box, seat, steering wheel @ body meeting tmr, go from there

• Work on daybreak pedal box 😩

• replace motor fuse, try to run again

• finish battery panels and send them to get water jet

• start manufacturing new locks

• start manufacturing vibration jig

• cooling stuff - intake, exhaust, mppt, calcs

Daybreak Progress

You tell me

finished sanding the bottom of daybreak

um

^

Questions people have

Have yall gotten good feedback in one on ones?

What do you need from me this week?
