4 Days until Final Design Review

  • Touch-base meeting Sunday or Monday evening?
    • Monday 8pm!
  • Mechanical team overview Wednesday or Thursday
    • Thursday 8pm!

Goals

  • Set days for final design review
  • Finalize pending action items:
    • Bonding testing
      • Updates to strategy
      • Plan for testing with current timeline
    • Wheel integration plan
      • Load calculations?
      • Material choice?
        • PETG?
    • FEA
      • Areas of focus, plan for timeline
        • Areas for FEA:
          • Drivetrain wheel hubs & Drivetrain wheel hub connectors
            • Test with statically for buckling and vibration
            • Test effect of heat on ABS connector? (Less of a priority)
          • Suspension
            • Bending on bogie connector plates
            • Impact on bonding tubes, specifically the fastener?
            • Vibration on fastener + thread lock coming loose (Less of a priority)
          • Differential
            • Impact of chassis forcibly wanting to tip
    • Sponsored items update?
      • Get in by the end of this weekend!
        • Demtool only for pieces we can't machine in-house or that have tight precision
        • Demtool wishlist → EVERYONE TO DO
    • CAD updates
