Race Car Dynamics

[pittersuk]

Been reading a book on race car vehicle dynamics, bloody good book!

friction Coefficients of tyres change all the time on race cars, just wondering what a typical value might be, for say a BTCC tyre or what you would ideally want it to be?

I gather there are few people on here that own or are apart of a race team. Do you look at a different tyre compounds for such reasons due to friction coefficients?
As you may have a great race car but it wont perform unless it has good tyres!!

Is that the Milliken and Milliken?

mu values can vary for alsorts of reasons, and it s possible to get a mu value of greater than one if you have a really good aero package. Think of the dynamics of a rolling tyre over tarmac, the rubber deforms around the stones etc and as a result you get a lot of grip, more than if it was just a tyre rolling on a polished surface for example.

So in answer to your question, anywhere from 0.35 on a really hard tyre running in a monsoon, to almost 1.5 for the stickiest possible slick with the right track temperatures etc etc (track temperatures important because there is a actually a chemical reaction taking place between the rubber and tarmac, something that is lost on a wet track)
