Architecture Discussion 09/27/2024

General

  • nodal on Matlab

  • Dynamics Syncs much more technical moving forward (after noodles ofc)

    • Share calc progress, dependents between systems, yapping

Suspension

  • Design Matrix result: Leading Arm / Double Wishbone

  • Quick Summary:

    • Macpherson: not possible for solar car due to chassis height requirements

    • Leading Arm: knowledge gap with dynamic integration

    • Double Wishbone: simplified and well documented integration

  • Objectives/Difference from MS15

    • Bellcrank →

      • RSU - can happen, planar linkages

      • FSU - potential 3d linkages (hard math), goal for 2d for less pain

    • Ackerman steering integration

    • RSU mass optimization, redesign due to loading distribution

    • Control arm bearing orientation

    • material aluminum unless welding needed

    • linkage research ongoing

    • welded tabs

    • Carbon fibre linkage arms?

Steering

  • Design Matrix results: Anti / Ackerman located above / inline with spindle

  • Quick Summary:

    • Anti-ackerman: bad for performance

    • Ackerman: better

    • Pulley: only invest if leading arm

  • Slip angle done

  • Go above suspension

    • Driver

    • space efficient

    • no u-joints maybe

  • Matt send dynamics course to steering

  • 15.5 Linkage changes under investigation, steering arm redesigned on parking brake mounting (regs dependent)

    • will know by next dynamic sync

Brakes

  • Task allocation: Brake pedal selection (floor/ chassis mounted)

    • OTS/ Custom

  • 15.5 pedal changes: floor panel to metal, limit switch rearrangement, 2-feet operation (dependent on chassis width)

  • 15.5 parking brake changes: handle?,

  • Estimate cost of 15.5 brake stuff by October 12

    • caliper, line, fittings,

  • Funding request because looking to do caliper testing
