Problems solved by technology
The generation of the elastic bandgap of the scattering phononic crystal mainly depends on its special internal periodic structure, so the geometric size of the structural unit cell should be equivalent to the corresponding wavelength, which requires that the size of the phononic crystal structure in this form is relatively large. There are certain limitations in the application of low-frequency vibration and noise reduction

The invention discloses a honeycomb structure plate integrating vibration suppression, light weight and high strength and a preparation method of the honeycomb structure plate, and relates to the field of honeycombs. According to the method, aluminum alloy sheets are subjected to linear cutting processing to obtain aluminum alloy square strips with grooves, and then the aluminum alloy square strips with the grooves are assembled to obtain a honeycomb structure; a middle oscillator layer is obtained by cutting an aluminum alloy plate into a specific shape similar to a racket through laser and then bonding a stainless steel wafer; and finally, a grid structure, the oscillator layer, an upper panel and a lower panel are assembled, bonding and fixing are conducted by using a high-strength epoxy resin structural adhesive, and finally, heating, pressurizing and curing are conducted by using a vulcanizing machine, thereby obtaining the multifunctional quadrilateral honeycomb structure. The honeycomb structure plate is applied to the field of materials.
Description
technical field [0001] The invention relates to the field of honeycomb materials, in particular to a honeycomb structure plate integrating vibration suppression, light weight and high strength and a preparation method thereof. Background technique [0002] Lightweight is the theme of evolution in nature, and it is also an eternal goal pursued by many mechanical engineering fields. Lightweight sandwich structures have been widely used in aerospace and other fields due to their advantages of high specific strength and specific stiffness. At present, the common lightweight sandwich structures are lattice structures and lattice structures. The honeycomb sandwich structure (hexagonal grid structure) is the most common sandwich structure in the modern satellite structure, and has achieved obvious weight reduction effect. [0003] However, due to the light weight and high strength of the honeycomb structure, its acoustic and vibration performance is poor. The conventional method...
