The present paper focuses on a study of the structural behaviour of bolster-beams under commercial operation conditions of railway systems, specifically in the dynamic conditions generated in events of over-traction and over-braking on the vehicle running. The proposed work is constructed based on the following phases: (i) analysis of the kinematics of the vehicle; (ii) development of numerical models, a model based on the multibody theory, and a Finite Elements model; (iii) development of experimental field tests; and (iv) development of simulations for a detailed analysis of the structural behaviour for a study of the strain distribution in the main bolster-beam. This study is applied to a particular case of a railway system that provides commercial service to passengers.enghttps://v2.sherpa.ac.uk/id/publication/issn/1896-0596bolster-beamstructural analysisfinite elements modelmultibody modelrailway testingStructural analysis of railways bolster-beam under commercial operation conditions: Over-traction and over-brakinginfo:eu-repo/semantics/article2021-04-12Martinod, R.M.Betancur, G.R.Restrepo, J.L.CastaƱeda, L.F.10.20858/tp.2016.11.2.7
