Abstract: The continuous 3D dynamic finite element model of steel-spring floating slab track is established to analyse the dynamic transfer characteristic of the floating slab track (FST) system, and make the elaborate explanations of vibration isolation efficiency and dynamic transfer characteristic with relative parameters. The method could make a detailed study of the vibration isolation according to different parameters of the system and provide a theoretical reference for the homemade of the floating slab tracks or similar productions.

Key words: spring-steel floating slab track, dynamic transfer characteristic, vibration isolation efficiency, finite element analysis, action frequency
