Evaluation of flexible rail rigidity and stress-strain state of elements of string rail track structure at the uSky center in Sharjah (UAE)

Abstract

Annotation: The study describes the arrangement of the string rail track structure and string rail; a test section of the track structure with flexible rail at the uSky Transport Center in Sharjah (UAE) is presented. Aim: analysis of rigidity of flexible rail under action of transport load and its dependence on temperature impact, as well as calculation of forces in elements of flexible rail are performed; the stress range and durability of the flexible rail under cyclic transport load from Unicar-T (tropical) are determined. Methods: The calculation was made using the ANSYS finite element analysis software package. Results: Analysis of the calculation results showed high efficiency and reliability of the proposed transport solution, taking into account the ratio of the material intensity of the string rail to the bearing capacity of the track structure.
