Abstract
Introduction. At speeds above 250 km/h, significant impact on the way have not only isolated, but also continuous irregularities. The research examines the effect of a specific type of uneven rolling, known as wavy wear of wheel thread described by harmonic functions. The aim of the study is to verify finite element model of wheel rolling along the rail.
Materials and methods. Finite-element method is the main tool to investigate the problem in question. The value of equivalent stresses and R65 profile rail displacements at different depth of uneven rolling of wave-type shape at 300 km/h wheel speed was determined.
Results. The authors designed finite-element model of interaction between wheel and R65 profile rail, which allows to consider uneven rolling of rail surface, and verified it using analytical dependencies and a similar study. A study was conducted on the effect of uneven rolling on contact force between wheel and rail. Contact force curve between wheel and rail at various depths of uneven rolling of periodic shape is presented. It is shown that force effect from wheel to rail at 300 km/h speed increases by 11 % with a change of defect depth from 0 to 0.2 mm, while displacements and stresses change is less significant (by 8.5 %).
Discussion and conclusion. Further validation of the presented finite element model would require its integration with railway superstructure, as well as data on the measurements of the rolling surface and measurement results of their impact on the track. It is also necessary to provide measurements in the direction of rolling circle, since such results are not publicly available. The presented model may be employed for the analysis of uneven wheel rolling effect on dynamic behaviour of high-speed main lines.
