METHOD FOR ASSESSING THE STRESS-STRAIN STATE OF A RAILWAY TRACK IN THE CONDITIONS OF THE FAR NORTH AND SIBERIA Russian patent published in 2023 - IPC B61K9/08 E01B35/00 

FIELD: railway transport.

SUBSTANCE: monitoring and assessing the actual state of the elements of the railway track and adjacent infrastructure in the Far North and Siberia. According to the method for assessing the stress-strain state of a railway track, in accordance with the structure of the track, three-dimensional finite element models of the studied section of the railway track with adjacent infrastructure are created, harmonic loading of three-dimensional finite element models is carried out, the stiffness of the elements of which corresponds to the rigidity of the frozen and thawed section railway track with the infrastructure adjacent to it. The results of harmonic responses of loaded three-dimensional finite element models are used to determine the frequency range of the measured parameters of the stress-strain state of track elements.

EFFECT: increasing the accuracy and reliability of determining the characteristics of the stress-strain state of the railway track in the conditions of the Far North and Siberia.
