Effect of the Mass of Prefabricated Floating Slabs on the Overhead Railway

A dynamic modal for the prefabricated floating slabs is presented in this paper on the basis of an analysis of floating slab track system.In the modal,the floating slabs are regarded as the rigid bodies supported by elastomer bearings.By exploring the effect of the mass of floating slabs on the train-bridge coupled vibration characteristics,a characteristic of mass of floating slabs on the floating slab track system is obtained.The optimum design method is proposed.
