thank you to everyone who helped out
Austin Auto Festival this weekend so just more outreach this weekend
🛠️ Chief Engineer
\uD83D\uDDE3 System Updates
🚨 Controls:
Updates
Motor Controller isn’t working (CAN Issues)
Ongoing Pedals work
First draft lighting board schematic done
Good progress on rear camera
Leader layout has begun
Week Plan
meeting with Eliana tomorrow to finish schematic
Pickle tonight to fix MC
Upcoming Deadlines
first draft lighting schematic
reviewed pedals schematic
backup camera feasibility
documentation on MC parameters, purchase MC if issues cannot be resolved
🔥 BPS:
Updates
Week Plan
Upcoming Deadlines
⚡ Power Generation:
Updates
MPPT ADC breakout board review
Starting MPPT fw makefiles
Array layout w/ Jason
Temp and Irradiance sense board schematic start
constant current driver re make schematic
PV capture database implementation complete; continuing database manager
training loop for model works :DD
Week Plan
finish up array layout w/ jason & send it to d2
Upcoming Deadlines
📻 Data Acquisition:
Updates
Array and battery sim are hard
Leaderboard progress continues
Week Plan
We try our hand at the challenges placed before us
Upcoming Deadlines
- RF Receiver Schematic
- IMU/RPM board proposal
🔋 Power Systems:
Updates
Week Plan
Power board layout 95% complete. Will get done very soon.
Board orders will go out very soon (eFuse test board, contactor driver, dataacq env board, active precharge (maybe))
Week Plan
Battery manufacturing (spotwelding) will begin next workday
Continue board development
Upcoming Deadlines
🔌 Electromechanical:
Updates
critical hardware back in car and harnessed
mock cooling intake done to send to regs
ready to manufacture mock modules
start characterization of a few cells with ps
Week Plan
have all battery box panel cutouts finished and dxfs created for waterjet
only layups will be a blocker then
Upcoming Deadlines
- EOD Sat - BB waterjet files
🧑🏭 Body:
Updates
Frame
first frame iteration finished → simming to begin
initial composite research finished → sandwich panel design and mount design next
Ergo
drivers sized → driver model can be finalized this week
Week Plan
Frame
Ergo
start simulating frame → get initial data for first iteration
create initial design ideas for frame jig
Ergo
continue working on steering wheel designs
finish up daybreak pedal box changes (test pedal jig, finish design)
start work on next gen seat
Upcoming Deadlines
- Nov 16, 2024 - Roll cage position/dimensions set
- Nov 16, 2024 - Driver Model finalized
🔩 Dynamics:
Updates
Unsprung: Unsprung ran sims on axle diameters, tried out SKF Sim Quick Pro for bearing and trailing arm geometry began development
Suspension: Suspension researched adams kinematics software, Kayla worked on refining her sketch to find non-hdpts defined values, trailing arm geometry began development
Steering: Steering worked on bump steer research + created a 3D sketch for Ackermann because I had anti for some reason + found the C factor of the old steering rack on the car + found issues with steering placement relative to the bounding box that we have + found a steering geometry that should work for new gen
Week Plan
Unsprung: 2 upright designs, 2 hub designs for Sami, Sumi, and Sohan. Jonathan works on rear swingarm which shows methods of motor and caliper mounting
Steering: Research bump steer optimization and have it implemented in CAD by workday
Suspension: Carter secures adams/dynatune, La’akea sims pushrods, Oliver sims control arms, Manas works with Jonathan on refining trailing arm hdpts
Upcoming Deadlines
- - Location of steering rack (code is broken, talking to Jacob about it. Will try to get a value that is worst case though.) - Steering
- - Length of tie rods (code is broken, talking to Jacob about it. Will try to get a value that is worst case though.) - Steering
- - Steering rack extender length (code is broken, talking to Jacob about it. Will try to get a value that is worst case though.) - Steering
- - Backup tires that aren’t Bridgestone are decided - Unsprung
- - Brake calipers and rotor size decided (Arav needs to get us this data) - Unsprung
- - Model bending forces and moments on the axle (working on throughout the week) – switched to doing sims instead - Unsprung
- - Axle diameter decided (doing the calcs for it throughout the week) - Unsprung
- - Axle length (already have somewhat of an idea) – switched to doing sims instead - Unsprung
- - Upper steering architecture selected (is in talks with ergo and suspension)- Steering
- - Bump steer design optimization - Steering
- - Finalize brakes and rotor config (Arav needs to get us this data) - Unsprung
- - Caliper and motor mount for Swingarm - Unsprung + Suspension
- - Decide bearings - Unspung
- - Suspension non hardpoint critical values decided - Suspension
- - Version 1 of Upright design in CAD - Unsprung
- - Version 1 of Hub design in CAD - Unsprung
- - Suspension Geometry Finalized - Suspension
💨 Aeroshell:
Updates
Aerodynamics
Members have been taught ANSYS
Composites
Battery box layup, worked on resin infusion research and test fixtures for composite panels
Week Plan
Aerodynamics
Everyone have a sim done of the parts that they have made by next workday
Getting into the flow of make variation, sim variation
Composites
Battery box, first frame panel test subject, maybe machining test fixtures (not sure on this yet, depends on materials), design molds for wire cutter
Upcoming Deadlines
- Nov 16. 2024 - all members have run sim
✅ Action items
- rray Array and Aeroshell meet on workday to discuss array layout after D2 meeting
- Electric figure out if driveday can be done during Thanksgiving
