Tire data into sims

[js10coastr]

For the teams that have made their own sims, what kind of tire model do you use? Has anyone tried using the MRA non-dimensional model?

[flavorPacket]

we had private flat trac tests done, and built our own model right out of RCVD. Put it directly into our in-house models and Carsim, had a few bugs but no big issues. Good correlation, too.

I use the MRA model for my sims. It's convenient if you are programming in MATLAB.

flavorPacket were your tests performed at Calspan? If so how much do you have to scale your grip down to get simulated performance down to real life levels?

You had private Flat Trac testing done? Wow. That sounds outrageously expensive, or someone is very generous.

[flavorPacket]

vince,

the tests were not done at calspan, but we still have scaling factors in our model.

exFSAE,

can you really put a price on doing things the way you think is right?

[Ayrton]

ExFSAE, you would be surprised how much you can accomplish if you set high goals.

There are a lot of people out there that are willing to work with FSAE teams and create opportunities; even if you think that you don't have a budget for it.
