ASSESSMENT OF THE POSSIBILITY OF INCREASING AXIAL LOADS FOR A GIVEN TRACK DESIGN

Abstract

Since Russia has one of the largest and most developed transport systems in the world, an integral part of which is the modern railway network, currently promising areas of development are associated with increasing the volume of supplies of ore and metallurgical cargo and cargo of the fuel and energy complex, especially taking into account its reorientation on the deep development of economic relations with Asian countries. An important role for the full realization of export potential is played by the Eastern range, during the operation of which a number of significant tasks are solved, aimed at the most efficient use of the existing railway infrastructure. At the same time, considering an increase in the throughput and carrying capacity of the railway track, it is proposed to develop heavy-haul traffic and the use of cars with increased load capacity by increasing the permissible axle load to 27–30 tons per axle. The article provides an example of a track strength calculation and an analysis of the obtained results of design stresses in VSP elements, and also a simplified design model was created using the numerical modeling method, with the help of which comparative data were obtained to assess the possibility of increasing axial loads for a given track design in a complex operation area .
