According to the structure characteristics of railway viaduct with light floating slabs, a frequency domain dynamic model of the vehicle-light floating slab track-viaduct bridge vertical coupling system is established. The Green functions are used to quickly calculate the receptance response of the system, and then the pseudo excitation method is used to further analyze the parameter influences of the floating slab on the vertical vibration excited by the track irregularity. The parameters of the floating slab have obvious effects on its vertical vibration, so as we strive to reduce the vibration and noise radiation of the railway by changing the parameters of the floating slab, the disadvantages to the vibration and noise control of the floating slab have to be taken into consideration.
