Ferrari @ monaco

Post

Why was ferrari slow at monaco ..is it because of the longer wheel base ...? or is it something to do with car and the track ..?



Sorry for the spelling mistake (ferrar) :)

the long wheels base is a hinderance at the tight twisty circuit of monaco, plus massa has not got to grip with the circuit yet. Sticking my neck on the line kimi might have done a beeter job but he struggled with underster all gp so....

i tot their was some problem with their longer wheel base not letting the car go around the track fast specially in the dam slower coners .

longer wheelbase 'not fitting' the track has definitely "something to do with car and the track" :wink:

I would really like someone to give a technical perspective on the longer wheelbase issue about monaco. Anyone??? :lol: :lol: :lol:

OK, when you turn the front wheels the car rotates around the rear ones, this increases the turning circle and in this case also means the car must turn in later to avoid clipping the inside of the corner with the rear, this is why lorrys and long vehicles swing out at a junction before turning in.

Mr Brawn had some words about it on Autosport the other day.

Oh ffs a slightly longer wheelbase isn't an issue. Longer wheelbase is certainly better for braking, which happens frequently at monaco.

For a longer wheelbase, geometrically you need more steering angle to navigate a given radius turn. This is true of low lateral accelerations, not necessarily of GP racing.

Without knowing steered vs slip angle correlations, slip angle curves, cg location, etc, you can't really say if a longer wheelbase is better or worse. It may be that in a heavy reverse Ackermann setup, as is the case at Monaco, the lateral force vector from the outside tire comes close to intersection the cg of the car, and making the wheelbase longer gives it a bigger moment arm to act on yawing the car into the turn.

Suffice to say I'm sure the Scuderia knows what its doing!

and whats ackerman setup ...?

You may want to invest in the Carroll Smith series of books.. Prepare To Win, Tune to Win, Engineer to Win, Drive to Win. All excellent.

I had hoped his fastener book would be called "Screw to win" but unfortunately it isnt!

I can't find it on wiki but the basics of convensional ackerman steering is that when you turn the wheels of your road car the wheel on the inside turns more than the wheel on the outside. F1 cars use anti-ackerman which means the outside wheel turns more the inside wheel. Don't ask me why.

Because the outside front has more weight on it, hence able to generate more slip angle before skidding.
