What is something you struggled with this week? What is something you are proud of this week?
SRR Key Takeaways/Next Steps
Overall
Ideas for reviewing drawings and structure for estimating weights
Get reasoning for 3 wheel by PDR
Suspension
Not being scared of aluminum welding and using that as a way to push ourselves
Quantify with just reasoning our parameters like 60-40 or FOS
Steering
Look further into gearbox design as the issues we were maybe afraid of aren’t as big of a thing
Look into tunability
Unsprung
Figure out brake disks
Tolerancing of bearings
Overall
we need to define how we are going to do reference points on the mold, and confirm that the knowledge is transferred
Aerodynamics
We need to solidify the plan for splitting up work and creating different parts of the shell(nose, tail, how to we avoid it messing up the overall geometrey)
Talk about roll cage in an intersystem meeting, because thats the next big thing that defines what we do
Composites
Figure out design of windshield with respect to the polycarb and what materials we should use
LOTS of wesley notes, not worth putting all in this spot since its lot of smaller specific notes
resin infusion is a risk and will cost a lot of money (vacuum)
consider having aeroshell PDR at the same time as dynamics and frame CDR
Be more thoughtful/less arbitrary with goals (i.e. goals were good, but have them bounded better, and be able to directly measure/compare them in the future
Really really review composites plan to ensure we can make good progress while reaching our key frame goals
Be more thoughtful in ergo design, think more about possible situations/applications (minimize oversight)
Difference between making a part that would be cool, and making a part that is practical and effective (i.e. carbon fiber steering wheel vs fiber glass steering wheel)
Rethink whether we really need so much of cooling, vibration dampening, etc
Have a good testing and simulation plan - know the basics.
Do composite testing but only test for your expected loading/impacts. Wastes time
Add FOS to only few parts and then design other parts to handle extreme cases
Shield all HV cables - probably a source of most EMF interference
properly fuse all battery connections
Match mechanical loading of rest of the car in terms of FOS/what we can see during transport
