Vibration absorption device and system based on acoustic black hole energy gathering effect
The invention discloses a vibration absorption device and system based on the acoustic black hole energy gathering effect, the vibration absorption device is composed of an acoustic black hole gathering device, a rubber coating layer, a hollow steel column and a plurality of metal transmission rods, a dynamic vibration absorber is composed of the hollow steel column and the rubber coating layer, and the dynamic vibration absorber is composed of a plurality of metal transmission rods based on the acoustic black hole energy gathering effect of the acoustic black hole gathering device. The acoustic black hole gathering device is connected with the dynamic vibration absorber through the metal transmission rod, and the steel rail vibration collected by the acoustic black hole gathering device is transmitted to the dynamic vibration absorber through the metal transmission rod, so that the resonance effect of the dynamic vibration absorber is enhanced, and the vibration of the controlled point is amplified. The effect of reducing vibration of the steel rail is achieved, and then the vibration suppression effect of the steel rail dynamic vibration absorber is improved.
本发明公开了一种基于声学黑洞能量聚集效应的吸振装置及系统，由声学黑洞聚集装置、橡胶包覆层、空心钢柱和若干金属传动杆组成，由空心钢柱和橡胶包覆层组成动力吸振器，基于声学黑洞聚集装置的声学黑洞能量聚集效应，将钢轨振动的能量聚集，从而放大受控点振幅，通过金属传动杆连接声学黑洞聚集装置和动力吸振器，将声学黑洞聚集装置收集的钢轨振动通过金属传动杆传导至动力吸振器上，从而增强了动力吸振器的谐振效果，起到降低钢轨振动的效果，进而提高钢轨动力吸振器的振动抑制效果。
