Sentence examples for modelling of railway from inspiring English sources

Dynamic modelling of railway track is a vital step in view of traffic noise reduction.

Petri-nets are used for modelling of railway interlocking components to ensure safety and deadlock free requirements (Giua and Seatzu 2008).

This paper presents a critical survey of the identification and modelling of railway noise sources and summarizes the current knowledge of the physical source phenomena (mainly rolling and aerodynamic sources) as well as the potential for noise reduction.

This article presents a simplified numerical model of railway trackbed layered structure.

The paper deals with numerical models of railway wheel noise occurring in narrow curves.

For this purpose, the model of railway line in scale 1 1 (Experimental stand DRETM II) was built, as a part of the experimental workplace of the Department of Railway Engineering and Track Management.

The method permits existing models of railway vehicles and track to be incorporated and it has application to any model of vibration transmission through the ground.

The numerical method considers a combination of Carter's two-dimensional contact theory, a two-dimensional elastic plastic finite element model and a vertical dynamics model of railway vehicle coupled with a curved track.

The numerical method considers a combination of Kalker's rolling contact theory with non-Hertzian to be modified, a linear frictional work model and a vertical dynamics model of railway vehicle coupled with a curved track.

An algorithm based on the global information of the train is designed to obtain a more effective travel advance strategy of the train than the TAS method proposed by Dorfman and Medanic [Dorfman, M.J., Medanic, J., 2004. Scheduling trains on a railway network using a discrete-event model of railway traffic. Transportation Research Part B 38 (1), 81 98].

Although they are critical components in railway vehicles, their modelling in the dynamic models of railway vehicles is usually relatively simple: it is usual to characterise them using a simple linear model formed by a spring and a viscous dashpot in parallel.
