Driver Placement Bias

Cooling Testing Results:

CAD design method

• This will be presented using a lecture format

• The goal of this presentation is to develop consistency in design across the board and ensure that people are implementing best practices while doing CAD

• What topics do people want covered?

  • Naming conventions

  • CAD organization, folders, naming features, reducing

• How do we want to approach reference dependencies - do we want to design in context of assemblies

Highlights

Does anybody have any highlights from the week they would like to share?

Blockers

It was brought to my attention that some people are having a difficult time knowing where/how to start since some design/architecture decisions haven’t been made yet. What are y’all having trouble with?

• We should implement the philosophy that designs can be started even without defined constraints. This involves incorporating enough flexibility in your design so that you can modify it once these constraints have been set.

• Finalized hardpoint locations (we can work with a general idea for now) but like also this isn’t exactly ideal

• Finalized hardpoint locations (we can work with a general idea for now)

• Front or rear biased (generally battery box and driver locations)

• Driver measurements

Workday Review

Suspension:

• Further progress on new member task of creating their own suspension

Steering:

• Looked into upper steering column and its relation to lower steering column geometry

Unsprung:

• Each member researched further and is starting to develop calcs for their section of research, started CADing practice unsprung parts.

Frame:

• Talked with suspension for clarification on what rear trailing arm and double wishbone approaches look like for frame

• Also got together an approach for designing around hardpoints and making reference sketches

• Frame Parameters spreadsheet created

Ergo:

• Driver Model outline is finished; will only change slightly based on ergo jig collected data/survey data

• Ergo and pedal jig plans are finalized; just needs to be reviewed before being manufactured

Next Workday Plan

General:

• Go over the reference sketch and get the HDPT-DYN-24 sketch to be a thing

Suspension:

• Check up on member progress on their suspension designs hopefully they are close to being done or are done

Steering:

• Talk to Jacob about lower steering column and geometry

Unsprung:

• Practice CADs for their parts (uprights for Sumi and stuff) should be a thing and can be reviewed. Continue practicing through more designs and getting a feel for unsprung and its relations

Frame:

• Go over general statics/solids intuition as applied to frame building

• Continue determining general roll cage dimensions and creating frame reference sketch

• Create varying designs for front and rear of chassis (new member task)

Ergo:

• Review and then manufacture the pedal jig → start Finish measuring drivers

• Continue adapting percy model with survey data and eventually measured data

• Generate a preliminary steering wheel design/manufacturing method

• Continue brake calcs

Daybreak Progress?

•  New Suspension Geometry - due Yesterday
•  New Wishbone Model - due Yesterday
•  Select Spherical Bearings - due two days ago
•  Bearing Mounting Scheme - due Yesterday
•  Bearing Mounting Design - due Yesterday

•  Progress on Refinishing bottom shell?
•  Shell to frame ideas?

• Pedal Box redesigning has progressed → Pedal Jig can be manufactured after review and new pedal/master cylinder location can be tested and verified

•  When are battery materials getting ordered
