Abstract

The invention discloses a pavement vibration energy recovery power generation device and method based on a three-dimensional super material. The device comprises a multi-cantilever beam annular structure, an upper half sphere case and a lower half sphere case, wherein the upper half sphere case and the lower half sphere case are made of the three-dimensional super material. The multi-cantilever beam annular structure is arranged inside a hollow sphere body formed by the upper half sphere case and the lower half sphere case. The three-dimensional super material sphere cases can realize the isotropic vibration wave gathering; the pavement vibration wave energy can be recovered to the maximum degree; the multi-cantilever beam annular structure can effectively convert electric energy; the damage to the pavement due to the frequent vibration can be reduced; meanwhile, the energy can be converted into electric energy, so that the effective utilization of the energy is realized.

Description

technical field [0001] The invention relates to the technical field of road vibration energy and metamaterials, in particular to a road surface vibration energy recovery power generation device and method based on three-dimensional metamaterials. Background technique [0002] Metamaterials are a very popular class of artificial materials for acoustics that have special properties that do not exist in nature. The wave-focusing property of metamaterials shows great application prospects in vibration energy absorption. Metamaterials are further divided into one-dimensional, two-dimensional, and three-dimensional. Among them, three-dimensional metamaterials have a broader application prospect because they can achieve omnidirectional vibration wave convergence. [0003] The noise in modern society is mainly low-frequency noise, including traffic low-frequency noise and electrical low-frequency noise. Among them, the vibration energy produced by road vehicles as a new type of ne...
