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

  • create initial design ideas for frame jig

  • continue working on steering wheel designs

  • finish up daybreak pedal box changes (test pedal jig, finish design)

  • start work on next gen seat

  • manufacture mock module

  • characterize a few battery cells and bin

  • 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?

Tabled discussions:

  • Being able to remove the master cylinders from Daybreak to test pedal box - talk to controls during leads meeting tomorrow

  • Keeping the sim/iterate process less repetitive for aeroshell

  • Coming up with a plan to accurately apply loads for suspension FEA

⤴ 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

    • Advait Joshi needs to clutch up on Statics

    • System updates:

      • 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

        • Body

          • test setups need to be setup with current frame iteration

          • comtune work with sgeering wheel design

          • design and testing o pedal jig

          • starting work on nect=gen seat utlizing data from ergo jig
