The key issues in designing ballastless track for high-speed railway bridges are to reduce maintenance and improve track smoothness by understanding fatigue damage characteristics. This paper is based on the principle of bridge-rail interaction and train-track-bridge coupling dynamics. the refined simulation model of bridge-CRTS I Bi-block ballastless track system is established by us... https://danddcollectiblers.shop/product-category/nee-doh/
