Vehicle max speed formula
Posted: Mon Aug 22, 2016 12:26 pm
Does anybody know which formula is used to define the vehicle maximum speed?
There's no explicit definition of top velocity in the prototype, so I've figured it's some sort of balance between friction and engine power, but attempts to approximate friction with linear and square functions did not succeed.
I've tried to describe the following vehicles
which stand for viscous friction and linear one (assuming that friction value in prototype stands for friction force coefficient: F=velocity^some_power * friction).
I used car as a reference point to set a constant multiplier.
However, first one undershoots the speed of raven vehicle and the second one is wrong for a tank.
edit: the cube formulae doesn't seem to work either.

with these formulae:
Code: Select all
max_speed= math.sqrt( effectivity*consumption/ weight / friction / const)
Code: Select all
max_speed= effectivity*consumption / p.weight / p.friction/constI used car as a reference point to set a constant multiplier.
