Can anyone explain me how to compute tyre forces with the Pacejka formulae ?

Here's a website that may help.

I haven't checked it but it looks OK.
Incidentally you should be aware that there are several magic formualae, with different numbers of terms.

In my data
A coefs range from a0 to a13 with a111 and a112
B from b0 to b12
C from c0 to c18
and also am0 to am9 and bm0 to bm3
Thanks

Un fortunatly the coefs for a Michelin tire are no longer available on the site i'v found them...
Anyway i'll try with other coefs.
Thanks a lot

a0:1.9
a1:16
a2:1440
a3:1800
a4:8.65
a5:0.14
a6:0.165
a6
a7
a8
a9
a10:-2.35
a111:-2.35
a112
a12:-14.9
with these coefs Sv=(a111*Fz+a112)*gamma*Fz+a12*Fz+a13
if you want a plotter for pacejka you could download the simulation racer at www.racer.nl and you will get a pacejka plotter in which you can alter the coefs.
Send you my curve.
