Abstract: The function and composition of a new rubber floating slab track system were introduced, in which rubber isolator is used as the elastic support element, owning the advantages such as small volume, self-damping, three-direction adjustable stiffness and low cost. Through numerical simulation calculation and laboratory model experiment, comparative analysis was carried out towards the vibration reduction system. The results have shown that the new rubber floating slab track system can satisfy the relative requirements in urban rail transit in terms of safety and vibration reduction performance, feasible for being used as advanced or special vibration reduction method in urban rail transit.
