Analysis of Limit Loads and 3D Modeling of Removable Equipment for Rail Transporters

The paper analyzes critical issues related to the reliability of transporting long rail strings exceeding 800 m in length along curved sections of the railway network of the Republic of Kazakhstan using specialized rail-transport wagons. An original methodological approach is presented for the analytical determination of limit force effects arising in the detachable equipment of flat wagons when negotiating track sections with circular geometry. A detailed threedimensional representation of the structure was created within the ANSYS computational framework to enable numerical simulation and analysis. The developed digital model was verified through a comparative analysis of theoretical and experimental data, demonstrating a high degree of accuracy (with an error margin not exceeding 5%). The results obtained allow for a more precise assessment of the structure’s safety under complex geometric conditions, which is particularly relevant in the context of modernizing the country's transportation infrastructure.
