| description | This paper analyzes existing quasi-static methods for determining the wheel load on the railway track and provides recommendations for their application under various operating conditions. The study examines the influence of train speed, track design, and track condition on the calculated dynamic load values. The results indicate that at high speeds, additional dynamic components must be considered for a more accurate load assessment. A comparative analysis of the examined methods demonstrates their equivalence within specific speed ranges, enabling their synthesis to expand applicability and improve calculation accuracy. The study also includes calculations for ballastless track, considering its increased stiffness. It was found that for such structures, the load calculation equations need to be adjusted, as ballastless track exhibits reduced deflection but higher transmitted dynamic loads. The updated equations proposed in this paper allow for a more precise determination of wheel loads for different types of rolling stock and track structures. The results can be integrated into mathematical models of railway track behavior to refine external load parameters. Additionally, reference load values are essential for railway track condition monitoring systems. |
