Methodology for calculating the strength of the pressure beam of freight cars

Abstract

This article presents the results of research aimed at analyzing and eliminating malfunctions arising in the overhead beam of freight cars. In order to ensure reliable and high-quality delivery of goods on railway transport and the effective use of the existing rolling stock, the designs of freight cars are being improved.
In the study, the main malfunctions arising in the overhead beam of freight cars were identified. These include beam fatigue, casting defects, and cracks that occur during operation as a result of maximizing load-bearing capacity. It is noted that such malfunctions can affect the safety of train traffic and lead to accidents and incidents.
In order to improve the design of freight cars, 3D models were created using SolidWorks and HyperWorks engineering programs and analyzed using the finite element method. The results made it possible to determine the values of stresses arising in the beam under load. Various load diagrams were analyzed, and optimal design parameters for increasing the strength of the overhead beam were proposed.
The research results showed the need to use new materials and technological solutions in the design of the overhead beam. And this will increase the service life of the wagons and ensure traffic safety.
