| Abstract: | 3D dynamic finite element model was established to analyse the dynamic transfer characteristics of the floating slab track(FST)system and to study the vibration isolation efficiency and dynamic transfer characteristics of the track structure with different design parameters and under different exiting frequencies.Results of analysis indicated that the adopted method can study in detail the effect of relevant design parameters of the floating slab on the efficiency of vibration isolation and provide a theoretical basis for the design and localization of floating slab tracks or similar products. |

| Keywords: | spring-steel floating slab track dynamic transfer characteristics vibration isolation efficiency finite element analysis exiting frequency |
