Analysis of the overlap section in a high-speed railway catenary by means of numerical simulations

Gregori Verdú, Santiago; Gil-Romero, Jaime; Tur Valiente, Manuel; Tarancón Caro, José Enrique; Fuenmayor Fernández, Francisco-Javier (Elsevier, 2020-10-15)

[EN] The transition between catenary tensioning sections is accomplished smoothly by overlapping a number of spans in each catenary section. This work presents an analysis of the overlap section in a high-speed railway ...
Analytical model of the pantograph¿catenary dynamic interaction and comparison with numerical simulations

Gil-Romero, Jaime; Gregori Verdú, Santiago; Tur Valiente, Manuel; Fuenmayor Fernández, Francisco-Javier (Taylor & Francis, 2022-01-02)

[EN] Catenaries are large cable structures which transmit electric current to trains through sliding contact with a pantograph. The finite element method is widely used to model this dynamic interaction problem and obtain ...
Análisis de la dinámica de una vía de tren bajo una carga móvil utilizando el método de elementos finitos periódicos

Aquilino Tarí, Francisco (Universitat Politècnica de València, 2024-11-20)

[ES] El objetivo de este trabajo es resolver la dinámica de una vía ferroviaria cuando el tren circula a una velocidad determinada. Este problema lo abordamos mediante la realización de un modelo de elementos finitos de ...
Dynamic response of periodic infinite structure to arbitrary moving load based on the Finite Element Method

Gil-Romero, Jaime; Gregori, S.; Tur, M.; Fuenmayor, F.J. (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] A common problem in railway engineering is the dynamic of repetitive structures subject to moving loads. Bridges, rails or catenaries are the most representative periodic structures, over which the train acts as a ...
Estudio analítico y por elementos finitos de impacto en placas

Gil Romero, Jaime (Universitat Politècnica de València, 2016-09-05)

[EN] The work is based on the study of simple impacts on rectangular plates made of aluminum and/or composite material, with various types of supports and for the second material with several stacking sequences. Analytical ...
Finite element periodic catenary model to perform HIL pantograph tests considering non-linear dropper behaviour

Gil-Romero, Jaime; Tur Valiente, Manuel; Gregori Verdú, Santiago; Correcher Salvador, Antonio; Fuenmayor Fernández, Francisco-Javier (Elsevier, 2022-11-01)

[EN] In this paper, we propose a general approach to compute the dynamic response of periodic infinite structures subjected to a moving load. The method only considers one repetitive block of the structure which is modelled ...
Hardware-in-the-loop pantograph tests using analytical catenary models

Gil-Romero, Jaime; Tur Valiente, Manuel; Correcher Salvador, Antonio; Gregori Verdú, Santiago; Pedrosa, Ana M.; Fuenmayor Fernández, Francisco-Javier (Taylor & Francis, 2022-10-03)

[EN] Pantograph hardware-in-the-loop (HIL) testing is an experimental method in which a physical pantograph is excited by an actuator which reproduces the movement of a virtual catenary. This paper proposes a new method ...
Hardware-in-the-loop simulations of a railway pantograph with a finite element periodic catenary model

Gil-Romero, Jaime; Tur Valiente, Manuel; Gregori Verdú, Santiago; Correcher Salvador, Antonio; Pedrosa, Ana M.; Fuenmayor Fernández, Francisco-Javier (Taylor & Francis, 2023-03-13)

[EN] The pantograph-catenary dynamic interaction problem is addressed by Hardware-in-the-Loop (HIL) tests to simulate the dynamic interaction between a numerical model (the catenary) and a physical device (the pantograph). ...
Hardware-in-the-Loop Test Bench for Simulation of Catenary¿Pantograph Interaction (CPI) with Linear Camera Measurement

Correcher Salvador, Antonio; Ricolfe Viala, Carlos; Tur Valiente, Manuel; Gregori Verdú, Santiago; Salvador-Muñoz, Mario; Fuenmayor Fernández, Francisco-Javier; Gil-Romero, Jaime; Pedrosa, Ana M. (MDPI AG, 2023-02)

[EN] Catenary-pantograph contact force is generally used for assessment of the current collection quality. A good current collection quality not only increases catenary lifetime but also keeps a stable electric supply and ...
Modelado dinámico de un pantógrafo ferroviario mediante el uso de redes neuronales artificiales

Gutiérrez Arnaldo, Sergio (Universitat Politècnica de València, 2023-09-29)

[ES] La obtención de modelos dinámicos de sistemas suele realizarse mediante ajuste de los parámetros a partir de medidas experimentales. Aun así, cuando se trata de sistemas complejos con comportamientos no lineales, la ...
