Description

Multistage honeycomb vibration reduction energy absorption device with vibration resistance and multidirectional impact resistance Technical Field The invention relates to the technical field of vibration reduction, in particular to a multistage honeycomb vibration reduction energy absorption device with vibration resistance and multidirectional impact resistance. Background The honeycomb structure has wide application in various fields of navigation ships, transportation, mechanical devices and the like due to the mature manufacturing process, efficient energy absorption and dispersion mechanism and good deformation energy absorption effect. The honeycomb products in the market at present are various, and the working principle of the vibration reduction technology is mainly based on the energy absorption performance of substances. When the honeycomb structure is impacted by external force, the honeycomb structure can transfer and dissipate energy in the collision process through the material of substances through the characteristics of the material, so that the influence effect of vibration is remarkably reduced. However, although the honeycomb structure is excellent in vibration reduction and cushioning, the honeycomb structure in the prior art has many limitations. On the one hand, the conventional honeycomb structure on the market is weak in the resistance against the multi-directional impact load, and the vibration reduction effect is often not ideal. Particularly at a given structural thickness, the vibration resistance of the honeycomb is difficult to significantly improve, which limits the application of the honeycomb structure in environments where complex loads need to be sustained. On the other hand, the impact resistance of the honeycomb structure is mainly represented by its axial or longitudinal load-bearing capacity, while the transverse load-bearing capacity is relatively weak, and cannot effectively support a large impact load. When the honeycomb structure is axially compressed, the cells are obviously deformed and folded so as to absorb a large amount of energy, but under the condition of transverse compression, the thin plates among the honeycomb cells are mutually extruded, so that the buffering and energy absorbing effects are greatly weakened. More importantly, in some real applications, such as applications in which marine ship equipment is subjected to vibration and impact environments for long periods of time, the honeycomb structure needs to bear impact loads from different angles and in any directions, and needs to be subjected to vibration environments for long periods of time. This requires that the honeycomb structure not only provide the necessary axial and transverse load carrying capacity, but also that its vibration resistance must meet certain standards. However, conventional honeycomb structures have difficulty meeting such multidirectional, high strength load bearing and vibration resistance requirements. Disclosure of Invention The invention aims to solve the problems in the background technology, and further provides a multi-stage honeycomb vibration reduction energy absorption device with vibration resistance and multidirectional impact resistance. The technical scheme adopted for solving the technical problems is as follows: A multistage honeycomb vibration reduction energy absorption device with vibration resistance and multidirectional impact resistance comprises a metal shell, wherein an open-pore hard rubber structure is arranged in the metal shell, a corrugated honeycomb structure is arranged in the open-pore hard rubber structure and is formed by uniformly arranging a plurality of honeycomb cells in a common edge mode, the honeycomb cells are formed by stacking and bonding a plurality of layers of small corrugated honeycomb cells, each small corrugated honeycomb cell comprises six corrugated thin plates, and the six corrugated thin plates are mutually interwoven to form an outer bone framework of the small corrugated honeycomb cell. Further, the open-pore hard rubber structure and the corrugated honeycomb structure are bonded together by adopting fiber resin, and the metal shell and the open-pore hard rubber structure are bonded together by adopting fiber resin. Further, the metal shell is internally wrapped with an open-pore hard rubber structure, and the open-pore hard rubber structure is internally wrapped with a corrugated honeycomb structure. Further, the open-pore hard rubber structure comprises four side rubber plates, a rubber rectangular frame is formed by the four side rubber plates, two sides of the rubber rectangular frame are plugged by an upper layer rubber plate and a lower layer rubber plate, and a plurality of openings with honeycomb cell sizes are formed in the upper layer rubber plate and the lower layer rubber plate.
