The invention discloses an impact damping vibration absorption device with an acoustic black hole structural body, and belongs to the technical field of steel rail vibration reduction. The device comprises a mounting base mounted at the bottom of a steel rail, the mounting base, an elastic damping body, a resonance mass body and a damping body internally provided with an acoustic black hole structural body are sequentially connected from top to bottom, an elastic hinge is further mounted between the mounting base and the resonance mass body, and the elastic hinge is located on one side of the elastic damping body; and the elastic damping body, the resonance mass body and the elastic hinge form a dynamic vibration absorber. The vibration absorber is simple in structure, the resonance unit bodies, the impact mass bodies and the acoustic black holes can play a role in vibration absorption, the vibration absorption effect of the vibration absorber is enhanced, adjustment is easy to achieve, and the application range of the vibration absorber is wide.
本发明公开了一种含有声学黑洞结构体的冲击阻尼吸振装置，属于钢轨减振技术领域。它包括安装在钢轨底部的安装座，所述安装座、弹性阻尼体、谐振质量体、内部安装有声学黑洞结构体的阻尼体从上到下依次连接，所述安装座和谐振质量体二者之间还安装有弹性铰链，且所述弹性铰链位于弹性阻尼体的一侧；且由所述弹性阻尼体、谐振质量体和弹性铰链组成动力吸振器。本发明结构简单，谐振单元体、冲击质量体、声学黑洞都可对吸振发挥作用，增强本发明的吸振效果，易于实现调节，本发明适用范围广。
