TL;DR: The aims of the benchmark are to assess the dispersion of results on the same simulation study cases, to demonstrate the accuracy of numerical methodologies and simulation models and to identify the best suited modelling approaches to study pantograph–catenary interaction.

TL;DR: In this article, a novel method to solve three dimensional cable structures based on the catenary equation is proposed, which is a generalization of a previous engineering application to compute the initial equilibrium of railway overheads.

TL;DR: In this paper, an enhanced catenary stiffness model and contact modelling based on lagrangian multipliers are proposed for dynamic simulation of catenary-pantograph interaction using simplified models, and the influence of both enhancements is discussed and investigated by means of an exhaustive comparison between most common simplified models and the method proposed herein.

TL;DR: In this article, an original hardware-in-the-loop (HIL) strategy aimed at integrating a multicriteria active control within the catenary-pantograph dynamic interaction is presented.

TL;DR: In this paper, a microthermo-mechanical approach has been used in order to model accurately the macroscopic phenomena of wear, and a plastic law for the normal micromechanical contact of asperities has been implemented in FEAP and a slight modification based on experimental results is proposed.
