Plans

Timing

General

Aeroshell

Find screws to fix canopy latch

  • no more than one workday

Look at more secure canopy hinge

  • control side to side movement more

Fix shell to frame

Install top-shell tilting mechanism

Widen wheel cutouts

  • make sure area between wheel access panels and wheel cutouts is strong enough

*we made need more but I havent looked at the car, these 2 are the only ones I’ve heard tho

Latch

  • no more than one workday

Hinge

  • 2 weeks?

  • possibly a freshman project, but I already know a lot more about hinging than anyone else so itll take a decent time for them to catch up.

Tilting

  • month?

Wheel cutouts

  • no more than one workday

Fergo/Structures

Frame

  • Spot weld areas that are not fully welded (behind roll cage foam)

    • New member welding practice

  • Repaint

    • Teach new members how to use spray gun

  • Driver shields

    • Maybe use a more rigid material like sheet metal

Ergo

  • Brakes

    • Potential design change to pedal box to accomodate for brake light

    • Rebleed brakes

  • Communications

    • Make better plan for communications

  • Minor fixes to seat

  • Steering wheel

    • Remake the steering wheel to accomodate for buttons

    • Remake the grip

  • Ballast Box

    • Fix latch

Spot Welding

  • 1-2 days

Painting

  • 1 day to paint

Driver shield

  • 1 week

Brake Lights

  • Design change - 2-3 weeks; May be hard for new member project

Bleeding Brakes

  • Possibly may have to reroute brakes as well if rusting is worse than expected - 2 day; New member project

Communications

  • Work with data acq and purchase depending on changes of plan - 1 month; New member project

Steering wheel

  • Work with electromechanical to mount buttons and design/manufacture - 3 weeks; can be a new member project

Ballast Box

  • Easy fix to ballast box latch - 1 week; new member project with manufacturing

Dynamics

  • Steering revision

    • Supports at the ends of the rack extenders to counteract bending forces from the wheel turning (pillow blocks with linear bearings)

    • Extra constraint of the intermediate steering shaft

    • Correct length tie rods

  • New Control Arms

    • Longer to increase suspension travel before bottoming out shock

    • Larger

    • Spherical bearings at upright attachment

    • Possibly rotate orientation of inboard rod-ends to align load pathing with structure of wishbones

  • New Shock Extenders

    • Will be a result of the control arm changes

  • Steering Revision

    • part acquisition and attachment will take 2 weeks - can be done by new member

    • design, material acquisition, and fabrication will take 2 weeks - can be done by new member

    • Design and fabrication will take 1 week - can be done by new member

  • New Wishbones

    • Design will likely take several weeks of iteration

    • Intend for a new member to do this

    • Machining will vary depending on approach

    • Tubular wishbones may be shorter, solid wishbones will be longer

    • If a CNC is needed, machining softjaws and running the CNC will extend the time needed

    • Overall this is a full-semester project

  • New Shock Extenders

    • Will likely take around a week to redesign then machine

Emech

  • New battery enclosure (potentially slightly different BPS)

    • try to keep cooling as similar as possible

    • roughly same bounding box

    • actually modular so modules can be swapped

    • will require flat layups

    • Finished battery pack by end of februrary

  • New enclosures

    • water/splash resistant

    • some form of quick release mounting (instead of directly attaching to pipe clamps or frame tabs)

      • new members

    • panel mount connections

      • new members

    • 2-3 weeks to design

    • 2-3 weeks for manufacturing if printing

  • Few minor changes to cooling for new battery/interfences with additions to the car

    • same design, maybe changing dimensions or positioning slightly

  • Completely new wiring

    • 3 workdays

      • can be reduced with more hands and work doing week

  • Combine controls hardware into dashboard

    • 1-2 workdays once controls hardware and other hardware positioning finalized

  • Data qa

    • radio mounting

    • leader board mounting

    • sensor mounting/routing/shielding

  • Battery

    • End of Feb

  • Enclosure latching

    • 4-5 workdays

      • designing, prototyping, testing

      • new member project

  • New Enclosures

    • 4-5 workdays

      • depends on how many have to be made and how long 3d printing will take

  • New Wiring

    • 3-4 workdays

  • All of these have pre req decisions that need to be made from both divisions so they can’t be started until a lot is finalized
