W. Czyczula, L. Chudyba, P. Koziol, M. Odrowaz, T. Wesolowski, "Energy Flow between Layers of Railway Tracks during Moving Loads", in J. Pombo, (Editor), "Proceedings of the Third International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 183, 2016. doi:10.4203/ccp.110.183

Keywords: energy flow, multilayer track structure, moving load, analytical and semi-analytical solution.

Summary

This paper builds on the authors' previous papers concerned with unit energy flow between rails and their foundation. The flow was studied by using a simplified railway track model. One of the basic results of these studies is the formulation of an empirical relationship between the railway ballast degradation measures and unit energy flow. In this paper, a more complex but still linear model of the railway track structure is introduced. The analysis carried out is limited to the vertical plane. The energy flow between several layers is analysed taking into account the steady state response of the multilayered railway track structure. The load is composed of two forces, i.e. constant and varying in time, both distributed along the track. Various combinations of loads and track parameters are assumed for the analysis of the energy flow between rails and sleepers as well as between sleepers and the ballast layer. New interesting results are presented and the main paper novelties are pointed out.
