Platform disc type vibration reduction structure based on acoustic black hole effect

The invention discloses a platform disc-type vibration reduction structure based on an acoustic black hole effect, which comprises a platform flat plate and a plurality of disc-type acoustic black hole structures connected to the surface of the flat plate in an array manner, the upper surfaces of the disc-type acoustic black hole structures are round planes, the lower surfaces of the disc-type acoustic black hole structures are arc-shaped surfaces, the arc-shaped surfaces rotate to form round bosses, and the convex surfaces of the bosses are flatly attached to the surface of the flat plate. The damping ring layer adheres to the edge of the lower surface of the disc. The bending wave energy on the platform flat plate is concentrated to the tip of the disc type acoustic black hole structure, absorption and dissipation of the bending wave vibration energy are achieved through the damping circular ring layer adhered to the surface of the acoustic black hole structure, the flat plate does not need to be removed an
