This is a brainstorming page for all initial sketches and SolidWorks models for the chassis design.

Rough Sketch

Rough CAD Outline:

Total outline:

Basic outline without cross members:

  • 4 hoops
  • Straight beam at the base (I beam) for support
  • Additional cross beams added to base for mounting points
  • Cross behind driver seating area
  • Triangular beams along sides, except at door area

Matt Suski

-All members triangulated

-7 hoops, one main, front roll hoop rear roll hoop, front wheel and rear wheel hoop, front bulkhead and rear bulkhead

-main hoop is one curved tube, with no bends (recommended by Student Formula Design Teams document)

-Three horizontal beams on the front and back to mount the control arms to

-door would be placed between main hoop and front roll hoop

Image result for tesla chassis

Lightweight chassis (does not conform completely to aerobody). Composed of just a chassis floor with a roll cage (just thick enough to mount suspensions and steering). This would also keep our center of gravity very low, which is good for dynamics.

The aerobody should be structural enough to support itself. If not thin extension members can be implemented from the chassis to help support the aerobody.

No reason for the chassis to be as large as the aerobody.





Imagine the Tesla bottom chassis but with a roll cage.

I forgot to do the rear wheel wells before I posted this, but imagine them the same as the front....

  • Involves 5 hoops
  • Uses an inward design for the rear wells where it angles inwards and juts outwards (allows for wheels to remain flush with the body without differing shape between the two hoops)
  • Two curved portions at the top. We could add one more hoop in the center of this
  • Front half of the middle area is for the door, rear half can be used to add support or create a space to enter the back of the vehicle for mounting

Side:

  • Conformed to aerobody design
  • Just the outer framing, no triangulation yet
    • will start placing support beams once outer frame is finalized
  • Next steps:
    • Map mounting points
