Progress in Modeling Railway Hunting Behaviors by Means of Chaotic Equations

This work presents some further achievements in modeling the hunting behavior of railway vehicles starting from experience in mimicking error processes in radio channels and from a recent work on hunting lateral accelerations, in which a first attempt to use similar chaotic equations has been recently proposed. Model sequences are modeled as weighted sums of chaotic functions, whose statistical features are matched to target sequences provided by experience or reliable mechanical multi-body procedures. Different examples are shown, various comments are presented, and some future work is outlined.
