looking for vehicule data base parameter

by Sebastien Tixie » Thu, 09 Jan 2003 18:58:02

hi,

i'm looking for a free data base where i could find vehicules and
tires parameter such as stiffness, load sensitivity factor,
longitudinal vs load curve, typical car angular inertia, tire spring
rate and damping factor, and other technical stuff like that, measure
from real stuff ....

regards,

Some decent racing tire data is available from Avon at:

Sebastian,

Does the English phrase, "In your dreams", translate to French?

In our experience, all this data is expensive to measure and what little is
available is scattered all over the place.  That's part of the reason why
our library is so valuable.  About the only place where a database as you
describe might exist is within a large car or tire company, and you can bet
that it's guarded carefully as a corporate asset.

Just as an example -- good luck getting matching vehicle data to go with
the Avon tire data (link below).

I'd love to be proven wrong, but I'n not going to hold my breath.

That's what i discovered by myself, but i thought, maybe i'm just not
looking at the right place :(

It's hard indeed. Very rarely I've seen some PAcejka numbers cross the
Racer forum for some tires.
What helps best I've found is some contacts in the automotive
industry. People with knowledge & tools to actually be able to create
a bunch of realistic parameters for you. :)

But it's scraping things together, certainly.
