The research of the influence of viscous interaction between wagon and container on the dynamic load during transportation by rail ferry

Abstract

This paper proposes the improved scheme of interaction of containers with the load-bearing structure of the wagon when transporting by rail ferry. In order to ensure the stability of the container balance in the event of fluctuations in the railway ferry, it is proposed to attach special structures to the support structure of the wagons. To reduce the dynamic loading of containers, a material with damping properties is installed on the internal surfaces of the superstructures. Mathematical modelling was performed to substantiate the proposed technical solution. It was found that the total amount of acceleration that acts on the container is 3.47 m/s2 (0.35 g), and on the load-bearing structure of the wagon 2.47 m/s2 (0.25 g), which is 38 % and 23 % less, respectively, for the acceleration values in the typical scheme of their interaction. The conducted research will contribute to improving the efficiency of combined transport through the international transport corridors.This paper proposes the improved scheme of interaction of containers with the load-bearing structure of the wagon when transporting by rail ferry.
