Updates/Blockers
Please update me on the progress you’ve made the past week. Do you have any blockers? YOU MOVE OUT OF THE WAY
Workday Review
Unsprung ran sims on axle diameters, tried out SKF Sim Quick Pro for bearing and trailing arm geometry began development
Suspension researched adams kinematics software, Kayla worked on refining her sketch to find non-hdpts defined values, trailing arm geometry began development
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
Aerodynamics:
Matthew taught ppl ansys, 1 person was able to fully run a sim over the course of workday
Composites:
Battery box layup, worked on resin infusion research and test fixtures for composite panels
drivers sized → driver model can be finalized this week
first frame iteration finished → simming to begin
initial composite research finished → sandwich panel design and mount design next
steering wheel designs (daybreak and nextgen started)
critical hardware back in car and harnessed
mock cooling intake to send to regs
Next Workday Plan - please break tasks down into sub-tasks
Sim all the CADs that have been made throughout the week for Unsprung
Steering will create CAD for the bumpsteer effects that they have been researching throughout the week
Suspension begin simming the control arms and pushrods. Finialize HDPTs
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
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
its really just CAD the shell until January 18th, so it may be repetitive, any tips on how to fix that?
start simulating frame → get initial data for first iteration
have all battery box panel cutouts finished and dxfs created for waterjet
only layups will be a blocker then
Daybreak Progress?
Created a preliminary design (CAD model) of the radial tubular intermediate steering shaft constraint
no shell rn so nothing, may just do prep over thanksgiving break?
idk yet tho
Ideas are there for canopy hinge and shell to shell, need to cook
nah
made intake mock before finalizing to get checked by steve and dan
car can drive theoretically
need to pump tires
Questions people want to ask:
What do you need from me this week?
✅ Action items
⤴ Decisions
Meeting Notes:
Two real workdays left before Thanksgiving Break
Concern about part-level design and progress thus far to thanksgiving break
PDR is Jan 18, the first Saturday after we return from winter break
We only have a limited amount of time until the break, it’s come to the point where we will probably have to do work over the break
Naming convention is a real concern right now the longer we wait to fix it the harder it will be to fix. Leads and sub leads must take initiative on this
Unsprung, in talks with calipers, bearings need to be set, haven’t looked too far into sensors. Might not have caliper selection determined by this week, still needs validation in order to make a selection. Preliminary design of hub+ spindle design by the end of this week. Projected date of selection is to have it done by the end of Thanksgiving break.
Steering ackerman geometry and sterring linkage hasn’t been selected. Steering geometry update: they have a position but they need to test it for bump steer, needs to validate with better values, needs to utilize/refine Jacob’s code. Came up with an issue with where the rack bounding box will be placed relative to ergo and front axle
Roll cage needs to be finalized by end of week (11/16)
PDR - CADs need to be made, general geometry is made,critical mounting points need to be fixed (belly pan tabs, etc)
Ergo next-gen pedal box design needs to start
Shell to frame may need to have by PDR
Shell to shell interface may also need to have by PDR
Geometry issues with the shell with simming the current shell
Workday Review
Dynamics
Manas and Johnnathen on trailing arm geometry
Steering 3D sketch of geometry
Concern with location of steering rack and ergo bounding box
hash out a plan for FEA
Aerodynamics
Teaching Ansys
Simming approach
goal is for everyone to have a sim done on the parts they have
Composites: battery box layups
composite test fixtures and resin infusion
Body
Driver model can be finizaled
frame first iteration done
how to integrate the composite sandwich panels and tubes together
Good work on the steering designs for next-gen and daybreak
