Dear Sir, by "non-linear interaction between wheel and track" I understand the finding of contact points, wheel rail contact characteristics (rolling radii difference, contact angles etc.), the related Hertzian Parameters, Kalker Coefficients etc. Am I right? Or did you mean something else? I may at least try to help you if you mean what I understood.
