12/16 Fergo Meeting

Impending Deadlines:

• 1/18 Mechanical PDR

  • CADs must exist and mostly frozen

  • Body 000 Assembly is created and completed

  • Approaches for validation of our designs is complete (i.e., system for simulating the frame, ergo parts, etc)

• Link to Combustion Body’s PDR:https://utexas.sharepoint.com/sites/ENGR-LonghornRacing/_layouts/15/stream.aspx?id=%2Fsites%2FENGR%2DLonghornRacing%2FLHR%20Combustion%2FLHRC%202025%20Design%20Presentations%2FPDR%2FLHRC%20Body%20PDR%202025%2Emp4&referrer=StreamWebApp%2EWeb&referrerScenario=AddressBarCopied%2Eview%2Ef1d9af04%2D16a2%2D45dd%2D884e%2D76bd7f10601e

• Can members present?

Action Items

Frame:

• Body reference sketch refined and pushed

  • Adjust roll hoop to accommodate updated driver model (aeroshell)

  • Update rear frame to match the new hardpoints (Ask Kayla about the rear shock position

  • Adjust front HDPT cross-bracing

  • Talk to Evan about new steering coloumn position to match driver model steering column position

  • Confirm location of ballasts and add to reference sketch

• Frame Sims - We want to be close to passing on most sims ← ?

  • We need RH sims set up and meshed

    • We probably want these passing above all because aeroshell is set to order their top-shell molds by 1/25

  • We need OC sims set up and meshed

    • Beam set up has all tube cross-sections to iterate in Mechanical itself

    • To what extent do we want to be passing on these sims?

• Up-to-date Frame added to 000 Body Assembly

  • (Higher-level assembly for Body: will be built from frame reference sketch, all larger subsassemblies will reference the origin of the reference sketch. All smaller parts can be mated in-context)

• Frame Jiggin approach is outlined

  • HDPT jig designs

  • Which ones we intend to machine/outsource

  • Rough welding plan

Ergo:

• Preliminary CADs for next-gen

  • Pedal box and brake pedal

  • Seat design (rough manufacturing plan)

  • Steering wheel

  • Dashboard? ← Controls/emech now? will it be on presentation

• Finished CADs for Daybreak

  • Finish daybreak pedal box redesign

  • Steering wheel

  • Close-outs

  • Belly pan tabs and materials finalized

  • Ballast box redesign

• Ergo CADs added to 000 Body Assembly

  •  

• Ballasts locations

• Individual is behind the seat

• Common is in the front, will be added to sketch

• Have both prelim and daybreak CADs done?

• Next gen concerns with progress by end of winter break, what can we have done, just have what progress we have so far and approach

• Main projects

  • Daybreak steering wheel and pedal box

  • Preliminary designs try to be pushed

• Ask Diya about scope of dashboard and if its ergos concern

• Continue Documentation on sim setups

Member Progress

• How are we doing to maintain progress during break for all members? How to keep accountability with everyone and ensure we’re all on the same page?

• Continue documentation

• How do we delegate members ANSYS sims?

• ANSYS learning hub? 🐒

• Hard deadlines, keep bugging them but not too much

• Doubt about members going through hella long ANSYS learing hub courses, look for shorter articles and videos

• Online tutorials on how to run the sims

• Ergo progress mostly done

• Idea to offload sims: OC impact cases

• Approach is to keep it as beam elements for OC load cases, learn more about why we choose to sim with beams instead of solids

• Composites? Will Maylin be on that

Josh Action Items

• Simulate roll cage B

• Begin creating a V4 for new driver model

• Refine frame ref sketch with corrected hdpts (front and rear) and ergo tubes

  • Ask Evan to update steering in ref sketch to match driver model

  • Ask Kayla about location of rear shock?

• Make 000 assembly and port over frame ref sketch and up-to-date frame

• Slide templates for PDR

• Ask Diya about the scope for the dashboard?

• Update member tasks in ClickUp

Kenta Action Items

• Add common ballast to front in reference sketch

• Finish Daybreak redesigns

• Push on Noah pedal box redesign

• Push on Akaash’s Daybreak steering wheel

Devansh Action Items

• Check in with Abby and Grace on jig design

• Check in with Maylin on composite research

• System for simulating roll cage

• Beam elements iteration set-up with cross-sections imported into Mechanical

• Curriculum for ANSYS Learning Hub
