Desarrollo y validación de técnicas para el cálculo de las frecuencias críticas de la vía ferroviaria

Rincón Contel, Fernando (Universitat Politècnica de València, 2021-09-07)

[ES] La vía ferroviaria, al tratarse de un sistema periódico de dimensiones infinitas, constituye un problema de características singulares dentro de la Ingeniería Mecánica. Al contrario que la mayor parte de problemas de ...
Prediction of rail corrugation using a rotating flexible wheelset coupled with a flexible track model and a non-Hertzian/non-steady contact model

Baeza González, Luis Miguel; Vila Tortosa, María Paloma; Xie, Gang; Iwnicki, Simon D. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)

[EN] This paper presents a model for simulating vehicletrack interaction at high frequencies for investigations of rail roughness growth. The dynamic interaction model developed employs a substructuring technique and the ...
Rail corrugation growth accounting for the flexibility and rotation of the wheel set and the non-Hertzian and non-steady-state effects at contact patch

Vila Tortosa, María Paloma; Baeza González, Luis Miguel; Martínez Casas, José; Carballeira, Javier (Taylor & Francis, 2014)

[EN] In this work, a simulation tool is developed to analyse the growth of rail corrugation consisting of several models connected in a feedback loop in order to account for both the short-term dynamic vehicle track ...
Simulation of the evolution of rail corrugation using a rotating flexible wheelset model

Vila Tortosa, María Paloma; Fayos Sancho, Juan; Baeza González, Luis Miguel (TAYLOR & FRANCIS LTD, 2011)

[EN] This paper presents a simulation tool designed for predicting the wear pattern on the running surface of the rails and for studying the evolution of rail corrugation after thousands of wheelset passages. This simulation ...
