pacejka data 1

[vitelblendo]

In order to simulate the dynamics of a vehicle, I need tire data in the form of Magic Formula coefficients.
Anyone knows where to find such data?

Thank you in advance for your help

You'll have to ask your tyre supplier (good luck) or read the original papers on the magic formula, which I'm pretty sure are published by the SAE.

I would look at the following resources:

Milliken Research:

ADAMS:

&

http://university.adams.com/goodyear/goody.htm

Other:

http://www.informs-cs.org/wsc00papers/135.PDF

&

http://www.racer.nl/reference/pacejka.htm

I got these from doing a Google search (

http://www.google.com/search?sourceid=navclient&q=pacejka+tire+model+data

or

http://www.google.com/search?num=50&hl=en&lr=&newwindow=1&q=magic+formula+tire+model+data&spell=1).

Google is always a good place to begin looking for information.

If you find any good information, please post it back to this thread.

Hope this helps. Best regards,

I haven't checked, but I bet none of them give actual coefficients. There seems to be a conspiracy of silence about this, and reading the technical agreement we've got with our supplier, I can't break it. None of the SAE papers I've read (for example) give actual coefficients. Sorry.

On the other hand, the curves generated by a FlatTrac machine are available on the web (I found them in 10 minutes of googling), and the actual equations are known, so it shouldn't take an enterprising person too long to devise a curve fitting algorithm to generate coefficients.

Of course, one problem is that you have to decide which Magic formula you are using - I've come across at least 5 variants. Cheers

I realize that this post is very old, however I found the following SAE paper most useful when I need some Magic formula data on a measured tyre for a range of normal loads.

d'ENTREMONT,K.L., 'The Behavior of Tyre-Force Model Parameters Under Extreme Operating Conditions,' SAE Paper 970558
