Vibration and noise reduction device for metamaterial

Abstract

The invention relates to the technical field of vibration and noise reduction devices, and discloses a vibration and noise reduction device for a metamaterial. The vibration and noise reduction device comprises a shell, and a mounting seat is arranged in the shell. According to the vibration and noise reduction device, a vibration and noise reduction middle piece of the metamaterial is arranged to be an upper piece and a lower piece, a gap is formed between the upper group and the lower group, a deformable space is provided for a quadrilateral middle piece of the metamaterial and an octagonal middle piece of the metamaterial, so that the metamaterial can be completely attached when the metamaterial is deformed, the circumstance that gaps are formed in the positions of all bending angles of the metamaterial due to bending when the metamaterial is bent is prevented, and the tightness, the impact resistance and the closed noise reduction performance of all the positions of the metamaterial during bending are improved; and the irregular hexagonal shape of a traditional metamaterial is changed, the completely regular quadrilateral shape and the completely regular octagonal shape are utilized for up-down connection, the stress points of all the positions of the metamaterial are balanced, so that the intervals of all the positions of the metamaterial during deformation and resetting are completely the same, and the stability of the device during vibration and noise reduction is improved.

Description

technical field [0001] The invention relates to the technical field of vibration and noise reduction devices, in particular to a metamaterial vibration and noise reduction device. Background technique [0002] Metamaterials: refers to the replacement of continuously distributed uniform materials in traditional structures with finely designed microstructures, which can be widely used in the design of various mechanical structures to achieve multi-functional integration of load bearing, vibration reduction, impact resistance, heat dissipation, etc. Design to promote the development of modern equipment in the direction of lightweight, integration, customization, personalization, and intelligence. [0003] At present, there are several problems in the use of metamaterial vibration and noise reduction devices. First, when the metamaterial vibration and noise reduction device is in use, since the vibration and noise reduction middle part of the metamaterial is integrated, the meta...
