the damn preview isnt working… ill fix it later -

According to WSC book: determining CG TW and WB can be quite arbitrary. Finding the CG requires overall weight and wheelbase - these two things do not have an explicit method of calculation. They are typically just values estimated from pre-existing designs.

...

  • estimate overall new weight

  • estimate CG

  • estimate weight distribution across front to rear axles

  • can get a rough est. of TW if the weight distribution w the assumed inputs are within our goal range of 60-70 front

I have estimated the CG and weight distribution of our new vehicle according to:

  1. WSC average values

    1. gave us a range of typical WB

    2. gave us examples of calculating CG distribution

  2. pre-existing daybreak weight values and dimensions - VDR

    1. battery weight - 30kg

    2. frame - ~187lbs

    3. 4.5 m length

    4. approx distance of significant masses from front axle

  3. system specific goals for the new car

    1. frame weight reduction

    2. occupant cell relocation

    3. 3 wheel assemblies

  4. regulations - give us a rough max and a min - regs

    1. battery - 30kg max

    2. max body length

    3. TW to WB ratio 1.5

my inputs:
