These unsupported track elements are often termed as hanging sleepers and they can lead to undesirable effects due to increased dynamic response of the train-track system, especially when the speed of the train is high. In this paper, we present a computation scheme in conjunction with the moving element method for the analysis of high-speed train-track dynamics accounting for hanging sleepers. The proposed computational scheme will be first verified by comparison with available analytical results. The dynamic response of a high-speed train traveling on a ballasted track considering unsupported sleepers is next investigated. Various factors affecting the response of the high-speed rail system including the speed of the train, the number of hanging sleepers and the pattern of the hanging sleepers will be examined and discussed. © The Authors, published by EDP Sciences, 2018. | Source Title: | MATEC Web of Conferences | URI: | https://scholarbank.nus.edu.sg/handle/10635/182095 | ISSN: | 2261236X | DOI: | 10.1051/matecconf/201814805007 | Rights: | Attribution 4.0 International |
