This paper builds a three dimensions finite element model to analyze the normal model of floating slab track by finite element software. Intrinsic frequency of floating slab track of two densities concrete slab is calculated in different combinations of rubber support pad stiffness and fastener stiffness. By analyzing result of the calculation, the influence of concrete slab density, rubber support pad stiffness and fastener stiffness for vibration charaeteristies of floating slab track system is abtained. It is an research to better understand the capability of reducing noise and vibration of floating slab track.
