Dynamic analysis of interaction between vehicle wheel with a metal protuberance and rail

Abstract

A new mathematical model “Vehicle - Track” developed from other mathematical models is used in the research to determine the interaction between the wheel with a metal protuberance and rail. Fourier series are used to mathematically describe the geometry of vehicle wheel with a metal protuberance. Calculations and analysed results, obtained by using the newly developed method, when a wheel defect has a metal protuberance, are presented in this work.
