【Abstract】 The slab track is one of the high speed railway track structures. In this paper, based on the theory of vehicle track coupling dynamics, a vehicle/slab track interaction model is developed, and the dynamic properties of slab tracks used in high speed railways are investigated. The effects of the elasticity and damping of the CA layer under the slab on system dynamics are also analyzed.更多还原
