A direct method for the extension of FastSim under non-Hertzian contact conditions

Gómez-Bosch, Jorge; Giner Navarro, Juan; Carballeira, Javier; Baeza González, Luis Miguel (Taylor & Francis, 2023-10-03)

[EN] In wheel-rail contact mechanics, there coexist different models characterised by their ability to reproduce the real phenomenon and the time associated with computing the solution. In simulation of the vehicle dynamics, ...
A linear non-Hertzian unsteady tangential wheel-rail contact model

Baeza González, Luis Miguel; Bruni, Stefano; Giner Navarro, Juan; Liu, Binbin (Elsevier, 2023-03)

[EN] The increase in computational capacity has considerably reduced the use of linear models for wheel/rail tangential contact, being currently replaced by theories that adopt non-linear formulations able to address the ...
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 ...
Multibody approach for railway dynamic analysis

Elsayed Abdel Hameed Amer Shaltout, Ramy (Universitat Politècnica de València, 2011-11-30)

In the work presented, a computational tool used for the dynamic simulation of railway vehicle systems was developed using multibody systems formulations. The model based on the multibody techniques developed by Shabana. ...
MULTIBODY APPROACH FOR RAILWAY DYNAMIC ANALYSIS

Elsayed Abdel Hameed Amer Shaltout, Ramy (Universitat Politècnica de València, 2013-03-14)

En este trabajo se ha llevado a cabo el desarrollo de una herramienta computacional para la simulación dinámica de vehículos ferroviarios. El modelo está basado en técnicas multicuerpo debidas a Shabana. Con respecto a ...
RESOLUCIÓN Y ANÁLISIS DEL PROBLEMA GEOMÉTRICO DEL CONTACTO ENTRE LA RUEDA DE UN VEHÍCULO FERROVIARIO Y EL CARRIL

Mataix Monzó, Cristina (Universitat Politècnica de València, 2024-07-18)

[ES] La geometría del contacto entre la rueda de un vehículo y el carril ferroviario es un factor determinante de la estabilidad de los vehículos, de la calidad del guiado en marcha, así como del desgaste de los perfiles, ...
Study on the allowed maximum amplitudes of low-order polygonal wear on resilient wheels based on operational safety

Zhong, Shuoqiao; Zhou, Xin; Sheng, Xiaozhen; Hou, Chuanlun; Qi, Yuan; Baeza González, Luis Miguel (SAGE Publications, 2024-08)

[EN] Following the extensive use of resilient wheels on trams, several subways in China have started pre-launch testing of resilient wheels. While it remains at an early stage, the long-term behavior of the wheel has become ...
Wear study of additively manufactured repair material for R260 grade rails

Rodríguez-Arana, B.; López-López, J.; Schiopetto, F.; San Emeterio, A.; Salas Vicente, Fidel; Pérez-Casero, I.; Veiga, A.; Ausejo, S. (Elsevier, 2024-08-15)

[EN] Additive Manufacturing (AM) has been considered as a promising method for repairing rails and extending their service life. In this work, the wear rates of twin-disc specimens produced through laser additive manufacturing ...
