ItemWhoNotes
Brakes

Adam

  • No update, pedal mounting
ChassisAdam
  • Sent out to review, VR3
  • Ready to resend, awaiting payment to be sorted out
  • Sims past well, chassis is quite light
  • Pushing to get tabs finished out
  • Jig is underway, hopefully construction done by end of Sep
DoorsDevon
  • Considerable progress, not done yet
  • Part of the second VR3 order
Driver ControlsAdam
  • Accelerator pedal does not hit the floor of the chassis
  • Parts have been ordered in, parts are also on the shelf
  • Large rack for asymmetric steering, linkages shift steering column
  • Sleeve yields at point on the steering collar, and stops on a collar (4"-5")
  • Tie rods will be a challenge, (Chassis interference on compression of suspension)
SuspensionAdam
  • Remained stagnant, changes made to the structure of the control arms
  • Use plates to seat the bearings
AerobodyAdrian
  • Shape defined. refined
  • Shape is bumpy
  • Optimizing for aesthetic and array optimization
  • Alias is used as a surfacing program (typical in automotive design)
  • Preliminary panelization was done, however the unrefined model caused issue
Battery BoxAdam
  • Tested battery packs
  • Pulled the right voltage and current, no issues
  • did not use typical manufacturing methods though
  • vibe testing was not done, an unresponsive professor does have a vibe test
