Track deflection analysis

Abstract

This review paper discusses various analytical models that can describe the vehicle-track system without requiring extensive and computationally demanding numerical models. All these analytical models aim to capture the behaviour of the track structure as a rail vehicle passes over it as accurately as possible, each in its unique way, depending on the assumptions they are based on. The objective of this paper is to evaluate their potential and limitations from different perspectives, such as computational simplicity, result availability, solution accuracy, and variability in solution forms.
