\uD83D\uDC65 Participants

\uD83E\uDD45 Goals

  • Individual System Requirements

  • Research/testing Checkpoint Review

  • Design Brainstorm and Development?

  • Daybreak Plan

  • Trial Workday Plans

\uD83D\uDDE3 Discussion topics

  1. come up with goals

  2. start brainstorming different options for system architecture (prototyping) - this doesn’t have to be dependent upon optimal characteristics

  3. continue conducting research and testing

  4. use findings to inform which options are good and which won’t work

  5. choose optimal option and revise design to match optimal characteristics

There is no point in making all of the critical decisions now. Make different prototypes with different designs/architecture so you have options to weigh. Don’t constrain yourself right away without having enough knowledge to determine those constraints. Making constraining decisions at the beginning without sufficient knowledge is premature, and those decisions can turn out to be the wrong decisions later on. Also, holding design to wait on optimal characteristics to be determined allows no actual progress on design to happen. Having a rough prototype that you can revise later to match optimal characteristics gives you a head start.

Research/testing Update

Design Brainstorm

Two probable designs so far:

  1. driver in the front

  2. driver in the back

...

3 wheel or 4 wheel

  • 3 Wheel is better but the only concern is tipping

Design Architecture Options

For a 3 wheel car:

Driver and battery position

  • Driver in the middle/front - battery box is behind the driver

    • advantageous since driver contributes the most mass

  • Driver is in the middle/rear - battery box is in the front or sides of driver

    • on sides of driver will increase width

Aeroshell - find optimal shell profiles (front and side) for the above options

  • Seat bottom shell into top shell

Dynamics

  • Front double wishbone suspension

    • external or internal

      • for internal suspension - top control arm mounted on top of frame

    • determine lengths of wishbones and ideal suspension travel

  • Rear suspension

    • Trailing arm (with two arms/one shock)

Design Philosophy

  • Skeleton model/reference sketches

  • Naming convention

    • 26-SYS-XXXX-RX-(Description)

  • Use of global variables and equations

Daybreak Plan:

  • won’t have a dedicated discussion, just a check in on progress

System

Aeroshell

What is broken/insufficient?:

What repair options exist?:

How much time do you believe each option will take?:

What level of involvement could new members have in these processes?:

What is your overall outlook on the feasibility of us repairing daybreak with such a capacity that we could pass scrutineering in FSGP 2025?:

Fergo

What is broken/insufficient?:

  • Fix some of the roll cage welds (if possible)

  • Roll cage needs to be painted

  • Brake light broken

  • Steering wheel (controls buttons and wiring is fucked)

  • Seat?

What repair options exist?:

  • weld frame : (

  • paint frame : (

  • get new brake light

  • Make new steering wheel

  • Idfk about seat, need to look into it

Dynamics

What is broken/insufficient?:

  • Upper and lower steering column

  • Wishbone lengths

  • Shock extender

What repair options exist?:

  • Remake wishbones

Trial Workday Plan:

  • What if someone wants to do two systems at once?

  • What materials do we need for your plans?

  • Logistics: how to go from one system to another, do you need the car for your plans, etc.?

✅ Action items

  •  Jason Heston Aidan Hodgin Continue practicing surface modeling in Solidworks
  •  Noah Hickman Joshua Miksits Start modeling a basic frame (make it adjustable by using reference sketches, global variables, and equations); look at roll cage designs
  •  Harshit Dalmia Start making a skeleton reference sketch for dynamics (make it adjustable by using reference sketches, global variables, and equations)
  •  Parthiv Shah Continue working on new pack/box design - refine design; come up with replacement enclosure for Daybreak
