Description

Technical Field

[0001] The invention provides a composite vibration reduction structure for vibration reduction, belonging to the technical field of vibration reduction. Background Art

[0002] In many fields, including construction, transportation, and electronic equipment, effective vibration reduction structures are needed to reduce the impact of external shock and vibration on the system. Traditional buffer structures often use springs, buffers, or shock-absorbing materials to absorb and disperse energy, but these methods may have some limitations and shortcomings.

[0003] First, conventional vibration reduction structures are often complex and require a large number of components and devices to achieve the vibration reduction effect, which leads to increased manufacturing and maintenance costs. In addition, due to their complexity, the installation and adjustment of these structures may become difficult, especially when applied in limited space.

[0004] Secondly, some vibration-damping structures may not provide sufficient stability and strength under certain stress conditions. This may lead to deformation, loosening or failure of the structure, making it unable to effectively reduce shock and vibration.

[0005] Therefore, it is necessary to provide a composite vibration reduction structure to meet the needs of buffering protection in various fields.

[0006] However, the existing traditional vibration reduction structures usually contain multiple components and devices, which require complex design, manufacturing and installation processes, resulting in increased manufacturing and maintenance costs. There may be stability and strength problems when facing high-intensity impact or vibration, which may cause deformation, loosening or failure of the structure. Traditional vibration reduction structures may require the use of a large amount of material, resulting in additional weight burden. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention provides a composite vibration-damping structure, comprising a concave hexagonal frame and a quadrilateral grid filling pattern. The concave hexagonal frame is based on a concave hexagonal area whose boundary is composed of six boundary beams. The quadrilateral grid filling pattern uses quadrilaterals as basic units for filling inside the concave hexagonal area. The filling is carried out in a regular manner to adapt to specific application requirements. The quadrilaterals are spaced a certain distance apart to form a continuous grid structure to provide greater flexibility and buffering effect.

[0009] As a preferred technical solution of the present invention, the concave hexagonal frame is made of nickel-titanium shape memory alloy, forming a frame with both ends concave inward. Secondly, the nickel-titanium shape memory alloy has unique properties and characteristics, which further enhances the cushioning effect and adjustability of the invention.

[0010] As a preferred technical solution of the present invention, the nickel-titanium shape memory alloy has excellent elasticity and durability and can withstand high-intensity deformation and stress. This enables the concave hexagonal frame to effectively absorb and disperse the energy of external impact and vibration, reduce the impact on the system, and maintain the stable working state of the structure.

[0011] As a preferred technical solution of the present invention, the nickel-titanium shape memory alloy is used to prepare a concave hexagonal frame. This preferred technical solution provides efficient buffering performance. When subjected to external impact and vibration, the elastic recovery ability of the nickel-titanium shape memory alloy can quickly consume and disperse energy, thereby reducing the impact and vibration on the system.

[0012] As a preferred technical solution of the present invention, the quadrilateral grid filling pattern is composed of nickel-titanium shape memory alloy. Through the quadrilateral grid filling pattern, the structure can effectively absorb and disperse the energy of external impact and vibration, reducing the impact on the system. The selection of nickel-titanium shape memory alloy and the design and layout of the quadrilateral grid further enhance the buffering effect and provide better protection and stability.

[0013] As a preferred technical solution of the present invention, the interior of the concave hexagonal frame is filled with a quadrilateral grid filling pattern. Through precise design and layout, the quadrilateral grid filling can maximize the use of space and provide a better buffering effect.

[0014] As another preferred technical solution of the present invention, the quadrilateral grid filling pattern is replaced by a triangular grid filling pattern.

[0015] As another preferred technical solution of the present invention, the triangular mesh filling pattern is stable and can disperse stress more effectively. In addition, the triangular mesh filling has stronger adaptability and can better adapt to surfaces of different shapes and sizes, thereby expanding the application scope of the present invention.

[0016] As another preferred technical solution of the present invention, the quadrilateral grid filling pattern is replaced by a hexagonal grid filling pattern.

[0017] As another preferred technical solution of the present invention, the geometric structure of the hexagonal grid filling pattern has higher compactness, fully utilizes the surface space, and reduces material waste. In addition, the hexagonal grid filling also provides a more uniform load distribution, which helps to reduce the local pressure of the structural stress point, thereby improving the durability of the material and the stability of the structure.

[0018] As a preferred technical solution of the present invention, three composite vibration reduction structures having a quadrilateral grid filling pattern, a hexagonal grid filling pattern and a triangular grid filling pattern are simulated and compared and analyzed.

[0019] As a preferred technical solution of the present invention, the composite vibration reduction structure of the quadrilateral grid filling pattern can better absorb and disperse stress under the same load, thereby improving the durability and stability of the structure. The design of the quadrilateral grid filling pattern not only takes into account the mechanical properties of the material, but also can effectively reduce the adverse effects of vibration and vibration on the structure.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The present invention can provide a compact structure, balanced buffering performance and structural stability by adopting a concave hexagonal frame filled with a quadrilateral grid pattern, thereby effectively improving the stability and strength of the structure.

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] In the drawings, the same reference numerals all refer to the same components. Example

[0024] like Figure 1-3 As shown, the present invention provides a composite buffer structure, including a concave hexagonal frame 1 and a quadrilateral grid filling pattern 2, wherein the quadrilateral grid filling pattern 2 is filled in the concave hexagonal frame 1, and a composite vibration damping structure is prepared using nickel-titanium shape memory alloy through metal 3D printing laser directional energy deposition technology.

[0025] A superelastic nickel-titanium alloy is further selected as the material of the concave hexagonal frame 1 and the quadrilateral grid filling pattern 2. The nickel-titanium alloy can return to its original shape after being deformed by force and unloading the force, providing excellent elasticity and rebound ability for the vibration reduction structure.

[0026] The two ends of the indented hexagonal frame 1 are indented inwards to form a concave structure. The size and shape of the indented hexagonal frame 1 can be adjusted according to the requirements of specific applications.

[0027] The inside of the concave hexagonal frame 1 is filled with a quadrilateral grid filling pattern 2. The filling adopts a regular filling method to adapt to specific application requirements. The quadrilaterals are connected at certain intervals to form a continuous grid structure to provide greater flexibility and vibration reduction effect.

[0028] Specifically, its structure is a composite vibration reduction structure consisting of a concave hexagonal frame 1 and a quadrilateral grid filling pattern 2. A composite vibration reduction structure having a concave hexagonal frame 1 and a quadrilateral grid filling pattern 2 in the middle is prepared by using nickel-titanium shape memory alloy and metal 3D printing technology and laser directed energy deposition technology. The concave hexagonal frame 1 can play a role of buffering force. When external impact or vibration acts on the concave hexagonal frame 1, it can absorb and disperse the impact energy to a certain extent, thereby reducing the impact force on the structure. The quadrilateral grid filling pattern 2 can enhance the stability of the concave hexagonal frame 1 while providing support and reinforcement, reduce the deformation and shaking of the concave hexagonal frame 1, and indirectly reduce the transmission of impact force, thereby reducing the weight and complexity of the composite buffer structure and improving the buffering performance, stability and strength of the structure.

[0029] A composite vibration reduction structure When external impact force acts on the concave hexagonal frame 1, due to the design of the concave shape, it can absorb and disperse the impact energy to a certain extent, reducing the impact force on the structure, and at the same time, these impact forces will be transmitted to the filled quadrilateral grid filling pattern 2 and the nickel-titanium shape memory alloy material. The quadrilateral grid pattern and the nickel-titanium alloy material can absorb and disperse part of the impact energy, thereby reducing the impact of external impact force on the structure and improving the stability and strength of the structure. Example

The filling adopts a regular filling method to adapt to specific application requirements. The triangles are connected at certain intervals to form a continuous mesh structure to provide greater flexibility and vibration reduction effect. Example

[0031] like Figure 5 As shown, the present invention provides a composite buffer structure, in which the quadrilateral grid filling pattern 2 is replaced by a hexagonal grid filling pattern 4 The hexagonal grid is further filled with a pattern 4. The filling adopts a regular filling method to adapt to specific application requirements. The hexagons are connected at certain intervals to form a continuous grid structure to provide greater flexibility and vibration reduction effect. Example

[0032] like Figure 6-8 As shown, the design of the concave hexagonal frame 1 contains three mesh filling patterns: triangular mesh filling pattern 3, hexagonal mesh filling pattern 4 and quadrilateral mesh filling pattern 2. Through simulation analysis, the purpose is to compare the performance of these different filling patterns under the same load conditions to determine their relative advantages. The quadrilateral mesh filling pattern 2 can better absorb and disperse stress, thereby improving the durability and stability of the structure.

[0033] In summary, the present invention effectively improves the stability and strength of the structure by adopting the design of the concave hexagon and the filling of the quadrilateral grid pattern, and uses the nickel-titanium shape memory alloy material to effectively improve the anti-buffering performance of the structure.
