Distribution of energy in the impact of railway freight wagons

Abstract

On the basis of laws for conservation of energy this paper examines an energy distribution during the impact of two railway freight wagons. During the wagons impact there are occur a longitudinal forces that significantly influence the tension and deformation of wagon carrying structure. In theoretical and experimental analysis there are various attempts to determine energy distribution and values and changes of longitudinal forces which disappear in a short time during the wagons impact. In the paper the certain methodology for determining the energy distribution is suggested, according to which it is possible to theoretically determine the values of forces which occur in a short time during the wagons impact. Special attention was paid to the influence of energy that is lost by impact. On the basis of such created theoretical model of energy distribution forces on wagons buffers which occur in impact are determined. Such theoretically obtained results are verified experimentally on test polygon for wagons impact, where was wagons Tadnss-z and Uacns-z tested.
