The conic profile of the wheels is what makes the train go around a curve without the need for lateral friction (the inner flange is just a safety mechanism). The fact that the axle is rigid is just a mechanical simplification made possible by the mentioned cornering dynamics. A train would work...

Thanks! I had already scouted those sources, but they are either too high level to be able to implement the model or the full text paper is not available. Do you have the last paper? Is it detailed enough? I may end up buying a copy of the original 2007 VDI publication, that is probably the best...

Sorry to be picky, but a train negotiates a curve using a completely different principle, namely the conic profile of its wheels and the variation of the working radius. It has little to do with the friction between the wheel and the track or the track pushing the wheels laterally.

Once you are done with booklet by Michelin pointed out by Roberto (@Roberto Teso ) above, this is a classical in the field: Tire and Vehicle Dynamics - 3rd Edition Authors: Hans Pacejka eBook ISBN: 9780080970172 Hardcover ISBN: 9780080970165 Imprint: Butterworth-Heinemann Published Date: 9th...

Yes, I am familiar with the booklet, it is actually very well written. There is a lot to learn from it. BTW, Michelin currently has one of the best tire models out there, the TaMeTire model. I am currently trying to know more about it, but the literature on it is really scarce. You are right...

Thanks for the mention @BvU . Not sure whether I have figured it all out, I feel like there is always something new to learn on the subject every day. I am in good company though. Professor Pacejka, who devoted his whole life to the study of vehicle tires, also thought there was a lot still to...

Hi there! Is anyone familiar with the Tametire tire model by Michelin? I understand it is based on the brush model and can take into account thermal and pressure properties of a tire. I was able to find only a very basic article online, but not a full description of how this model is able to...
