I just weighed one because of time. The weights of tires will be included with data so youll get it soon. Just intersting that you can lose almost 8 lbs off the car just switching to 10 inch tires plus what ever rim weight you drop. Substantial weight loss from my eyes. It will be interesting to compare the data between the 13's and the 10's to see what real advantages and disadvantages there are between them.

Hi all,

Day Two of testing at Calspan went well. One more day tomorrow.

We've been able to negotiate another day of testing on the current contract to follow sometime later this year. By then we may have some Avons to test (Dr. Woods has been working hard, but Avon has been less cooperative than Goodyear or Hoosier).

We are also now able to announce that Mike Stackpole of Stackpole Engineering Services will be providing TTC members with Pacejka/Adams models of the data. (Details to follow later.) This in addition to the Nondimensional Tire Model already to be provided by Milliken Research and, of course, the raw data.

There's one more day of testing tomorrow. I'll let you know how it goes.

Is the raw data in Tydex format? I'm currently writing Tydex 1.3 import and post
processing tools in Matlab and would be happy to pass them on to anyone wanting
to look at the raw data in more detail.

CALSPAN splits our data into Fy_pure and F_combined and my scripts reads in all
the files and divides off the Fx_pure data and stores the whole lot in a single
Matlab structure. My plotting routines then talk to the structure.

Hungry for data...

FSAE TTC Registrants,

Testing was completed on Friday. Right now Calspan is performing some post-test reduction of the data. Stackpole Engineering Services and Milliken Research Associates are fitting their models to the tire data. I expect to mail DVDs containing the raw data, the tire models, photos of the tires and videos of the tests by the end of next week (8/12).

Edward

If I'm able to judge again next year, I'll eagerly await the data - and as importantly, discussion of what the individual teams have done with it!

Could you tell us what model is used for the Pacejka data, e.g. '89, '94 or MF-Tire?

Thanks,

When I talked with Mike Stackpole we discussed 94, 96 and MF-Tyre. I'm not sure which one he's settled on. Right now he's working on modeling the data (as is Milliken Research). I still hope to get DVDs mailed at week's end to FSAE TTC members.

Edward

I am anxiously awaiting the data and was wondering if there was an update on the status of the DVD's.

The DVDs are still waiting on the Stackpole model and the Calspan decals. The new target is Monday for shipment. I'm as anxious as anyone to get these out the door....

Edward

Any news?

Good news!

DVDs are being burned as we speak and will be shipped tomorrow.

Edward

Hi all,

DVDs have been shipped to all FSAE TTC registrants who have paid the $500 registration fee in full. Our website (http://www.millikenresearch.com\fsaettc.html) contains a spreadsheet of finances which lists those schools who have paid. Your DVD should arrive within the next week.

The DVD contains a file "DVD_Contents.PDF". Please look there for a guide to what's on the disk.

And, of course, your questions and comments are always welcome.

Edward

Has anyone received their DVD? I have yet to receive Iowa State's.

Thanks.

I have not received Cardiff Universities copy either but we did have a problem with our payment which might have delayed things.

I know that Cincy got theirs about a week and a half ago.

Some of the teams still owe money (like 10 bucks) because they didnt send enough on the exchange from payment deals with banks and such. If you dont have it and you did something like that then email ttc. I know edward was saying that some of the oversees teams were skanked by the bank for additional charges that put them under the required amount.

we received ours yesterday (9/13).

Rob,

We're on top of our finances, thank you. We've worked with all the teams that were shorted by various banks and resolved all these issues. A DVD has been mailed to all paid teams.

By the way, Iowa reports getting theirs today--it was semi-lost within their University. If you haven't gotten yours, do a little detective work in your engineering department mailroom first.

By the way, it's a *data* DVD and probably will not play directly on your TV, even though it has videos on it.

Edward

Edward, What type of files are those video files? I'm having troule figuring out how to play them on my mac.

Thanks
