Duke University Motorsports is a student group that designs and builds open wheel, single seat race cars to compete in the Formula SAE competition sponsored by the Society of Automotive Engineers. The team consists of Duke students from both Pratt and Trinity, in all classes. The purpose of the team is to provide students with a way to gain practical design and manufacturing experience in a fun and challenging setting.

Almost end of summer update

School's starting soon, we have our first recruiting event for orientation week on Wednesday (3:15-4:30 in CIEMAS atrium in case anyone is actually reading this...), and I'm well on my way putting together the full car model (well, half a car, and the other half is mirrored).

Bullet points after the jump...

What's done:
  • Suspension is done finally after figuring out the bell crank, shock mount, and ARB packaging.
  • Steering geometry is done.  More ackermann this year and shorter steering arm so that we can use an off the shelf rack.
  • Wings mounts done- the rear wing will be carbon fiber tubing with some custom aluminum pieces ot hold the tubes together and an x-brace to make sure the system is statically determinate
  • The front wing will use foam core/carbon fiber mounts and bolt onto the frame just behind the bulkhead
  • Bodywork design is more or less finished, and clearance for everything so far has been verified.
  • New throttle body for this year - single roller design for packaging reasons
What needs to be done still:
  • Bodywork and diffuser attachments - I have these more or less figured out, I just need to add a couple of surfaces to the current bodywork
  • Steering - I need to measure the rack because the model I have isn't complete.  The steering rack has a different housing and sits a bit lower this year (stupid bump steer) and so the mounts need to be redone.
  • Integrate the rest of the parts onto the car - drivetrain, new WHUBS, intake, exhaust (the design is more or less done)
  • New gas tank (a seat model would be nice to have - maybe someone will make one this year...)
  • Carbon fiber a-arms - doable this year in my opinion, but we'll have a backup set of steel ones too.
