for dynamic analyses of railway track structures, the algorithm of solution is very important. for estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. for studying the effects of axially beam on the ela...

This paper presents a system-based model for the fatigue assessment of old, deteriorating riveted railway bridge connections, which are built up of a number of basic components. A finite element model of a typical, short-span railway bridge is used to convert train loading into probabilistic fatigue load spectra via Monte Carlo train simulations. Uncertainties in terms of loading, resistance an...

This work is devoted to the analysis of vibratory response High-Speed (HS) multi-track railway bridges composed by simply-supported spans. In particular, it aims investigate influence three geometrical aspects usually disregarded in numerical models used evaluate Serviceability Limit State traffic safety such structures: (i) deck obliquity, (ii) presence and correct execution transverse diaphra...

Abstract In this paper, a dynamic interaction model of the coupled system railway bridge, foundation, subsoil, ballast, track, and high-speed train is presented, with special emphasis on longitudinal between track bridge structure, taking into account flexibility ballast. After description system, equations motion are given separately for each subsystem. The discretization bedded rails performe...

Bridge bearing damage is unavoidable in railway engineering. This work presents an investigation on the model of bridge and its influence dynamic responses high-speed train-track-bridge system. Primarily, mathematical description explained detail, which then compared with traditional linear model. Then a 3D considering established based interaction theory. Adopting model, influences single-poin...

This paper investigates the handover performance on high speed train (HST) via different speed under three scenarios, which are viaduct environment, cutting environment and urban area. To provide stable wireless service, we adopt Long Term Evolution (LTE) for high speed railway (HST) system. Moreover, we consider the effect of speed on handover procedure. Interchannel interference (ICI) caused ...
