Dependency Tree & Timeline

Please link you dependency trees and timelines (as discussed during last leads meeting) below:

Blockers

What is blocking you from starting designing (CAD - even if just preliminary/prototyping)? Do you have any other blockers?

  • Geometry but that is accounted for in the timeline

  • Figuring out how to use better reference sketches

  • Are we changing array size(how much)

  • Finalized driver model/roll cage bounding box → ergo jig manufacturing and collected data

  • Frame reference sketch → rear hardpoint reference sketch (front is done alr)

  • Brake calcs finishing→ caliper and rotor selection from Dynamics

  • Maximum sizes although we are designing everything to be flexible - once we have max/target sizes we can modify

Workday Review

  • Timeline made

  • Unsprung worked on our mockup cads, caliper/brake calculations, trailing arm design and collaboration with suspension

  • Steering talked to Jacob about RMS error, code, and geometry optimization

Aerodynamics:

  • decided on 2 part top shell

  • split up everyone into their actual tasks

  • maybe a little bit too much high level yapping that they couldnt get involved in which wasnt great

Composites

  • continued work on and finished array cooling layups

  • Started work on daybreak

  • cleaned pickle bc ppl are showing up according to nathan

  • sanded a large metal sheet

Frame:

  • Mini solids/frame design lecture

  • Frame concepts (front and rear) designs continued, close to having preliminary design

  • Frame reference sketch created → will have 1st iteration this week

  • Composites Research continued → first round of research due this workday

Ergo:

  • Pedal box redesign continued (getting closer, pedal ratio redesign finished)

  • Brake calcs continued (again, blocked currently)

  • Seat outline created for more accurate driver model

  • Ergo jig design done → manufacturing this week

  • Battery review done, ready to start manufacturing

  • Adjustable angle vibe table jig skeleton done

  • Intake and exhaust started for battery box

Next Workday Plan - please break tasks down into sub-tasks

  • New members join us on newgen geometry design

  • Unsprung begins working on CAD for newgen rather than old gen

Aerodynamics:

  • Esther goes over how she made daybreak

  • Either ANSYS lecture or more time spent working on the parts they have been assigned.

Composites

  • Continue surface prep on Daybreak

  • Continue research and start working on testing w/the materials that were just ordered (assuming they arrive)

  • Continue sanding metal sheet

  • Frame ref sketch 1st iteration finished → move to adding weldments

  • Ergo jig built → data measurements begin

  • Pedal jig printed? ?

  • Manufacturing plans, who’s doing what, hardware, stock, and part inventory

Daybreak Progress?

  • From what dynamics understands, y’all are going to do it

  • Canopy hinge and shell to shell parts have been assigned to new members and work has actually started

  • Frame welding soon?

  • Battery review done, ready to start manufacturing

Questions people want to ask:

What do you need from me this week?

✅ Action items

  •  Have some sort of internal dependency tree for leads tomorrow - Everyone
  •  Make a defined dynamics reference sketch (doesn’t have to have exact values, just has to be defined) by EOD Tuesday - Harshit Dalmia Kayla Lee
  •  Have an overall frame bounding box for aeroshell (includes roll cage position, frame max height, frame length, and width in front and rear) by EOD Tuesday - Joshua Miksits
    •  Get an idea for battery bounding box and driver model to finish a preliminary reference sketch
  •   Have a discussion about reference sketches with Jason
  •  Rough draft for PVDR by Monday - Everyone

⤴ Decisions

    Notes:

    • Review standardized global coordinate system

      • +z → longitudinal forward

      • +x → lateral left

      • +y → transverse upward

    • Pay attention to align part with this coordinate system (SolidWorks default coordinate system)

    • It is fine for smaller parts to be defined not aligned with the referfence sketch origin

    • Subassemblies need to be defined relative to a reference sketch (i.e., control arm subassemblies, etc.)

    • Reference Sketch Discussion

      • A part, not an assembly

      • Key features that define geometric properties and location of systems

      • Everything derived from HDPT sketch

      • Review naming convention in Confluence

    • Have a dependency tree with a set of items that are agreed upon by both the subleads and systenm leads

    • Blockers

      • Aeroshell

        • Frame and Dynamics reference sketches need to be done asap with all critical architecture, begin working on spaceclaim for bounding boxes

        • Dynamics needs suspension geometry, suspension reference sketch

        • Frame needs to have a 3D reference sketch done by EOD tomorrow

        • We need to begin part level design
