Hi all

I'm currently working on a final year project at Uni, my topic is the dynamic modeling of race cars, in particular a formula 1 type vehicle. I have a problem though modeling the drive train, since I need some data for the gear ratios in an F1 car to do this, which don't get published. I just need some 'ballpark' figures, so my results won't be completely off. Does anyone have any suggestions what to use?? I was thinking about trying to find data on older models, but that wouldn't work with the rest of the data I'm using (it gets hard to decide if your results make sense or not).

Cheers lucy

Hi Lucia, that sounds a very cool project!

A suggestion, although a little left field, could be to see if any F1 games describe gear ratios - I know on many of them you can adjust this element of the car, although I don't know if these are based on reality.

I also ask around - but like you say, it's not something often banded about.

it will be hard to get exact data as the ratio's change at every track.

Try contacting one of the teams, McLaren, Williams et all, I know that may seem daunting, but it's not like you're after anything that's hyper top secret, they dont even have to be specific, just some general help is all you're after.

I'm sure their PR / tech departments would love to help someone like you. And anyway, what do you have to lose by asking?

Contact the teams defo, they might even been interested enough in your finial year project and the qualification your doing it for to consider employing you. . .

I suppose you could find out the top gear easy enough. If you think drivers are redlining at some tracks in top. You could then see what there max speed is at speed traps.

Look at the regs for tyre sizes work out the circumference of the rear tyres, work out there rotational speed. divide the engine speed (redline 18k rpm) by wheel rotation speed you will get a ratio. if you look at onboard shots at a single race you could do that for a a whole gearbox. you cold also work out the final drive ration at that point also. so from there you could hypothesize the gear ratio.

If you find onboard footage that shows both the rev counter and the speedo, then i'm sure you could easily calculate the gear ratio for basically every gear shown from there...??

If you're really stuck try what Stephen suggested, i could nip onto rFactor (supposedly the most accurate racing simulator game) and see what gear ratios they give for the '07 BMW, and you could plug them in and see if they work in reality (so to speak). It may give you a decent baseline to work from even if they're not quite right.

Sorry, typo, but thanks for the hyper-critique.
