Study of stress concentration on the surface of a freight car traction clamp

\nThe article presents a comprehensive analysis of the influence of loads on the structural integrity of a railway train elements. The focus is on load calculations using the Femap software package, which provides accurate modeling and analysis of mechanical systems. The study is aimed at identifying potential points of failure and stress concentration in the traction clamp as part of the automatic coupler of a freight car. The main problem addressed in the article is assessing the strength and durability of the traction clamp under operating conditions. The relevance of the study lies in the context of ensuring the safety and reliability of railway transport. The results obtained can be used to optimize the design and production process, as well as to develop recommendations for improving the design parameters of traction clamps, thereby reducing the likelihood of destruction and accidents.\n
