The vibration absorption device for the railway vehicle comprises at least two vibration absorption sets, each vibration absorption set comprises vibration absorption units with the same number, the vibration absorption frequencies of the vibration absorption units of different vibration absorption sets are different, and the vibration absorption frequencies of the vibration absorption units of the same vibration absorption set are the same. The vibration absorption units of each vibration absorption group are uniformly arranged on the surface of a component of the railway vehicle; the vibration absorption unit comprises a mass block and an elastic damping block, a first glue joint layer is arranged between the mass block and the elastic damping block, and the elastic damping block can be fixed to the surface of the component through a second glue joint layer. The requirement for vibration and noise reduction can be met, and meanwhile the light weight target is achieved. 本实用新型涉及一种轨道车辆用吸振装置及轨道车辆，其中，轨道车辆用吸振装置包括
