REQUIREMENTS FOR TRAIN-TRACK-BRIDGE DYNAMIC INTERACTION ANALYSIS

<p>The analysis of the dynamic interaction between the train, track, and bridge is crucial for ensuring the performance of railway infrastructure and the safety of railway traffic, especially on high-speed rail systems. This paper examines the key requirements for analyzing the dynamic interaction between the train, track, and bridge, with particular emphasis on the guidelines outlined in UIC Code 776-2. The analysis includes the structural strength of the bridge, passenger comfort, and the overall safety of railway traffic, ensuring a comprehensive evaluation of the entire railway system. Specifically, the paper examines the impact of continuously welded rails, which are widely used in modern railways due to their improved performance and reduced maintenance needs. The dynamic behavior of the train, track, and bridge is analyzed to confirm the structural integrity of the system, mitigate vibrations, and enhance passenger comfort. UIC Code 776-2 serves as a key reference for understanding the design and performance requirements for analyzing train-track-bridge dynamic interaction, guaranteeing that safety standards are met while optimizing efficiency. By evaluating the dynamic performance of the train, track, and bridge components, potential risks can be assessed, and strategies can be developed to mitigate them. This research contributes to the development of more resilient railway systems, ensuring the safety of both passengers and infrastructure.</p>
