Validation of a new model for railway overhead line dynamics

Abstract: This paper presents details of a new model of railway overhead electric power line dynamics for prediction of contact wire-pantograph contact forces and wire uplift. It is validated against data from EN50318:2002, and against data from track tests conducted at Network RailÕs Melton Rail Innovation and Development Centre using a class 395 high speed electric multiple unit. Its advantage over previous approaches is its implantation in a commercial nonlinear finite element package allowing application for a wide … Show more

“…This work extends the method developed by Beagles et al [18], using a finite element representation of the wire geometries. Four geometries were used during this study and Figures 3-6 show the geometries created during the modelling process of the four models used throughout this paper, shown vertically exaggerated and horizontally compressed.…”

“…The cantilever mast, which is normally made of H-section steel column, is a support of OHLE for only one or two tracks. Although the concept of OHLE is simple, the problem is poor dynamic behaviors of OHLE are needed to develop (Beagles et al, 2016). Due to the extreme environmental events and severe periodic force, such as an earthquake, in surrounding area may cause damage to the track and OHLE structure especially mast structure, this can lead to the failure of the electrical system (Shing and Wong, 2008;Robinson and Bryan, 2009;Taylor, 2013).…”
