Shrnutí:Anti-slip devices are essential for ensuring railway parking safety in various settings including arrival and departure lines, intermediate stations, and locomotive depot access routes. With the advancement in railway technology, anti-slip systems have progressed significantly in automation and intelligence. Thereby, these have become a critical component of parking safety measures. The Hydraulic Anti-Slip Device for Railway Arrival-Departure Tracks by Signal & Communication Research Institute (TFY-YH) anti-slip system is hydraulically driven. This enables higher braking than other types of anti-slip systems. This study focuses on the TFY-YH anti-slip system. It develops a finite element simulation model to systematically analyze the displacement, arrival time, and speed of the piston rod, as well as the variations in the accumulator oil pressure during the braking and releasing processes. The pressure-holding performance of the system is evaluated, and methods for improvement are proposed. Furthermore, the relationship between the stopping position of the train and the braking/releasing time is established. A method for determining the stopping position is also introduced. These observations provide a theoretical foundation for the intelligent control and monitoring of anti-slip systems. Additionally, these provide insights for enhancing railway safety and operational efficiency.
