  •  Vehicle weight that we use to design is 720 kg.
    •  Would want to get a more updated quantity of how much the current assembly weighs.
      Would need to include at least: Chassis tubes, Dynamics assembly, Battery Box, Seats, and more.
    •  Can work from a baseline how much the Chassis weighs and then see how any further modification creates how much percentage weight change
  •  Should do onsite measurements and inspection of any implementation method before finalization. This is because there are inaccuracies with the welded Chassis assembly.
  •  We will not model the current thin Bottom Panel and put it into simulations in hopes of contributing to structural integrity
    •  There are too many inconsistencies on the physical bottom panel, e.g. too many wrinkles and unevenly distributed patches of carbon fiber
    •  There were also too many issues with manufacturing it therefore it should not be considered at all
    •  It is also not within our scope or capacity to model a half built bottom panel

Options for Reinforcement

Expand
  •  Review previous
    •  Consider reviewing MS12 simulation files and documentation to learn more about what setups and assumptions that they used
  •  Adding chassis tubes, e.g. more tubes, thicker walled tubes, larger cross section tubes
  •  Sheet metal across a plane of tubes
    •  Carbon fiber panel has better strength-to-weight ratio
  •  Carbon fiber panels across a plane of tubes
    •  Very good strength-to-weight ratio
    •  Involves more manufacturing and time. It also has to be manufactured properly to be effective.
    •  Do we make any CF panels accurately? Have we performed destructive testing on CF panels yet?
      •  Not yet. Would need to be completed within Material Testing Project which is led by Tommy Tran
  •  

Housekeeping Reminders

Please document your work in a confluence page for any work completed for Midnight Sun.
For this specific project, it would be highly advised your documentation includes the following information:

  •  Directly Responsible Individual (DRI)
  •  Advisor or Reviewer
  •  Dependencies
  •  Location of work files, e.g. simulation files.
    Include file name and folder path.
  •  Date
  •  Child pages to separate and document sections of your work
