Description

Technical Field

[0001] This utility model belongs to the field of building structure vibration reduction technology, specifically, it relates to a composite metal damping device. Background Technology

[0002] Vibration isolation and energy dissipation technology is an advanced vibration control technology that involves installing energy dissipation dampers at points of relative displacement within or between a structure to dissipate input vibration energy, thereby reducing the structural vibration response. The energy dissipation damper is the core and key component of this technology, directly determining its effectiveness and success.

[0003] Over the years, researchers have developed various types of energy dissipation and vibration dampers. Based on the materials used in their energy dissipation components, commonly used energy dissipation and vibration dampers in engineering can be broadly classified into mild steel metal energy dissipators, viscous fluid energy dissipators, friction energy dissipators, and composite energy dissipators. Among these, viscous fluid energy dissipators typically involve stringent sealing conditions, requiring extremely rigorous manufacturing processes. Friction energy dissipators, because the friction force is related to the normal stress acting on the friction surface, often experience stress relaxation during use, leading to difficulties in achieving the expected energy dissipation performance. Metal energy dissipators have a relatively simple structure and do not involve leakage or stress relaxation issues, exhibiting good stability. However, since they utilize the elastoplastic yielding of metals for energy dissipation, irreversible elastoplastic deformation occurs after the energy dissipation effect is achieved, often resulting in changes to product performance and the need for large-scale replacements.

[0004] To address these performance and application issues and shortcomings, some researchers have begun to focus on and emphasize the research of composite energy dissipators based on different energy dissipation mechanisms. However, due to the vast differences in engineering practices, the performance parameters and tonnage specifications required for energy dissipators vary significantly from project to project. Current technical solutions fail to adequately consider the applicability of the products to actual applications, mechanical parameters, and the limited adjustability and range of tonnage specifications, thus directly affecting and limiting their applicability and application scope. Furthermore, current technical solutions also fail to adequately consider practical issues such as manufacturing efficiency, cost, and subsequent maintenance. Therefore, changes in product parameters require the remanufacturing of molds, making it difficult to achieve large-scale mass production, thereby hindering the improvement of production efficiency and the reduction of manufacturing costs. In addition, during use, current technical solutions also suffer from the problem of requiring the replacement of the entire energy dissipator due to partial damage to energy dissipation components, thus increasing the difficulty and cost of subsequent maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a composite metal damping device, which can change and adjust the overall mechanical parameters of the damping device by simply increasing or decreasing the number and composition of the damping components, thereby realizing damping devices of different tonnage specifications and mechanical properties, greatly improving the applicability and application range of the damping device. It is not only suitable for vibration reduction of machinery, but also for vibration reduction of engineering structures of different sizes, which can improve the production efficiency of the damping device and has a wide range of applications.

[0006] To achieve the purpose of this utility model, the technical solution adopted is as follows: a composite metal damping device, including an upper linkage body and a lower linkage body, and at least one damping component is provided between the upper linkage body and the lower linkage body. Each damping component includes at least one damping element. The damping element includes two connecting plates and a composite material body fixed between the two connecting plates. The composite material body is formed by alternating layers of flexible material and steel plate and high-temperature vulcanization.

[0007] Furthermore, the flexible material is rubber, viscoelastic material, or polyurethane.

[0008] Furthermore, the composite material body has at least one central hole inside, which is filled with soft metal.

[0009] Furthermore, the soft metal is lead, aluminum, or copper.

[0010] Furthermore, the upper linkage mounting end has a downwardly extending extension 1, and the lower linkage mounting end has an upwardly extending extension 2, with the damping component installed between the side of extension 1 and the side of extension 2.

[0011] Furthermore, both the upper linkage body mounting end face and the lower linkage body mounting end face have corresponding guide grooves, and guide posts are installed in the two corresponding guide grooves.

[0012] Furthermore, the upper linkage mounting end has a downwardly extending extension, the thickness of the lower linkage is less than the thickness of the upper linkage, and the damping component is installed between the side of the extension and the side of the lower linkage mounting end.

[0013] Furthermore, the upper linkage mounting end has two downwardly extending extensions, the thickness of the lower linkage is less than the thickness of the upper linkage, and the damping component is installed between the side of the extension and the side of the lower linkage mounting end.

[0014] Furthermore, the upper linkage mounting end has two downwardly extending extensions 1, and the lower linkage mounting end has an upwardly extending extension 2. The extension 2 is inserted between the two extensions 1, and the damping component is installed between the side of the extension 1 and the side of the extension 2.

[0015] Furthermore, the plurality of damping components are arranged in a quincunx pattern or a rectangular array.

[0016] The beneficial effects of this utility model are: 1. The mechanical parameters of this utility model can be flexibly adjusted, facilitating the creation of shock absorbers of different tonnage specifications. It boasts strong applicability and a wide range of applications. In practical applications, due to varying specific circumstances, the required tonnage specifications of shock absorbers are diverse and varied. The energy dissipation component of the shock absorber determines its tonnage and mechanical parameters. This utility model features a modular design for the energy dissipation component, allowing for easy adjustment of the overall mechanical parameters of the shock absorber by simply adding or removing damping components. This enables the creation of shock absorbers of different tonnage specifications, significantly improving the applicability and application range of the shock absorber. It is suitable not only for vibration reduction in machinery but also for vibration reduction in engineering structures of varying sizes.

[0017] 2. This utility model allows for the selection of corresponding installation methods for different building substrates, thus making it applicable to installation in special construction scenarios and ensuring the vibration reduction effect of the building. At the same time, this utility model provides different installation structures for different building substrates, enabling it to meet the installation needs of different building substrates and broadening its applicability.

[0018] 3. This utility model facilitates large-scale industrial production, significantly improving production efficiency and reducing production costs. In vibration reduction engineering, due to different design parameters, the tonnage and specifications of shock absorbers used in practice vary greatly. This results in a low usage frequency for shock absorbers of a certain tonnage and specification. Currently, most manufacturers create separate molds for each specification of shock absorber, leading to low mold utilization and difficulty in forming a large-scale mass production operation mode. This utility model features a modular assembly form, transforming the energy dissipation component of the shock absorber into multiple smaller-tonnage damping components. These damping elements form a damping assembly, allowing energy dissipators of different tonnages to be combined and assembled using different numbers of damping elements. This enables manufacturers to mass-produce damping elements, facilitating mold standardization and assembly line operations, thereby significantly improving production efficiency, reducing unit production costs, and improving product quality.

[0019] 4. This utility model is easy to replace and facilitates later maintenance. The energy dissipation component is the core of the shock absorber. Currently, during the use of shock absorbers, local damage or alteration of the energy dissipation component often necessitates a large-scale replacement of the entire shock absorber. This is not only labor-intensive and complex, but also time-consuming, labor-intensive, and costly, resulting in unnecessary waste. This utility model has the advantages of modularity and assembly. When the damping component is partially damaged or altered during use, only the problematic individual damping component needs to be replaced. Furthermore, the assembly-type feature greatly simplifies the replacement process. The modular energy dissipation element can be disassembled and installed to complete the entire replacement process, significantly reducing the workload. The entire process is quick and convenient, significantly improving replacement efficiency and reducing replacement costs, avoiding the unnecessary waste caused by complete replacement.

[0020] 5. Excellent durability. The damping element of this invention uses a composite material body composed of alternating layers of steel plates and flexible materials as the damping element. The flexible material body is made of rubber, viscoelastic material, or polyurethane, and the central holes in the flexible material body are filled with lead, aluminum, or copper. The flexible material provides good elastic recovery force, and the intramolecular friction of the flexible material and the lead, aluminum, or copper provided damping energy dissipation efficiency. Unlike metal energy dissipation components such as mild steel, which will undergo irreversible elastoplastic deformation after performing energy dissipation and face replacement, the composite material body as an energy dissipation element has good self-recovery performance. In addition, when using lead, aluminum, or copper to provide damping energy dissipation capacity, after the lead, aluminum, or copper performs damping energy dissipation under external load, it can recover to the mechanical properties before the load through automatic molecular crystallization. Therefore, this invention has good self-recovery performance and durability, avoiding the frequent replacement of metal energy dissipation components such as mild steel after external load, and greatly reducing the replacement frequency.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0025] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1 like Figure 1 , Figure 2 As shown, the composite metal damping device provided in this embodiment includes an upper linkage body 1 and a lower linkage body 2. Both the upper linkage body 1 and the lower linkage body 2 extend in a vertical direction and are located on the same vertical line. The upper linkage body 1 is located above the lower linkage body 2. At least one damping component is also installed between the upper linkage body 1 and the lower linkage body 2. The thickness of the damping component extends in a horizontal direction.

[0027] The upper linkage 1 has a downwardly extending extension 11 at its mounting end. Extension 11 can be a steel material separately installed on the side wall or end face of the upper linkage 1, or it can be a reinforced concrete structure integral with the upper linkage 1, or it can be a composite structure of concrete and steel. Regardless of the structure of extension 11, extension 11 and the upper linkage 1 can be an integral structure or be fixed together by fasteners. At the same time, the lower linkage 2 has an upwardly extending extension 21 at its mounting end. Extension 21 can be a steel material separately installed on the side wall or end face of the lower linkage 2, or it can be a reinforced concrete structure integral with the lower linkage 2, or it can be a composite structure of concrete and steel. Regardless of the structure of extension 21, extension 21 and the lower linkage 2 can be an integral structure or be fixed together by fasteners. The extension 11 and extension 21 are arranged in a staggered manner, with the upper end of extension 21 being higher than the lower end of extension 11. When the damping assembly is installed, one end of the damping assembly is installed on the side wall of extension 11, and the other end of the damping assembly is installed on the side wall of extension 21.

[0028] When there is one damping component, one end of the damping component is located at the center of extension 11, and the other end of the damping component is located at the center of extension 21. When there are multiple damping components, the multiple damping components can be arranged in a rectangular array or in a quincunx pattern between extension 11 and extension 21. The specific number and specific arrangement of the damping components can be adjusted according to the actual situation.

[0029] Each damping assembly includes at least one damping element 3. When each damping assembly consists of one damping element 3, both ends of the damping element 3 are fixed to extension 11 and extension 21, respectively. When each damping assembly consists of multiple damping elements 3, the multiple damping elements 3 can be stacked sequentially to form a damping assembly. When the damping assembly is installed between extension 11 and extension 21, the first damping element 3 in the damping assembly is fixed to extension 11, and the last damping element 3 in the damping assembly is fixed to extension 21. The damping element 3 includes two connecting plates, and a composite material body is fixed between the two connecting plates. The composite material body consists of alternating layers of flexible material and steel plate, which are vulcanized at high temperature to form a single unit. The flexible material provides good elastic recovery force.

[0030] In actual use, the number of damping elements 3 in each damping assembly can be adjusted according to the distance between extension 11 and extension 21, and the number of damping assemblies and the arrangement of multiple damping assemblies can be adjusted according to the required tonnage and mechanical parameters.

[0031] In some embodiments, both the mounting end face of the upper linkage 1 and the mounting end face of the lower linkage 2 are provided with guide grooves 4. The guide grooves 4 on the upper linkage 1 and the lower linkage 2 correspond to each other. Specifically, the guide grooves 4 can be formed during the prefabrication of the upper linkage 1 and the lower linkage 2, or two parallel guide rails can be installed on the mounting end faces of the upper linkage 1 and the lower linkage 2 after prefabrication. In this case, the gap between the two guide rails forms a guide groove 4. The extension direction of the guide groove 4 can be determined according to the actual damping situation. For example, the extension direction of the guide groove 4 can be consistent with the thickness direction of the upper linkage 1. At the same time, guide columns 5 are installed in the guide grooves 4 on the upper linkage 1 and the lower linkage 2, so that when the seismic force exceeds the constraint force under the normal use conditions of the damping component, it can play the function of seismic isolation in multiple directions.

[0032] In some embodiments, the flexible material is one or more of ordinary rubber, high-damping rubber, viscoelastic material, and polyurethane. The flexible material can be selected according to the actual situation while ensuring the damping effect of the damping element 3.

[0033] In some embodiments, the composite material body is further provided with a central hole, which can be one or more, depending on the size and strength of the composite material body; at the same time, each central hole is filled with soft metal, which is cylindrical, and its two ends abut against two connecting plates respectively.

[0034] In some embodiments, the soft metal is lead, aluminum, or copper. Unlike mild steel and other metal energy dissipators, lead, aluminum, or copper will undergo irreversible elastoplastic deformation after performing their energy dissipation function and will need to be replaced. This gives the composite material as an energy dissipation element good self-recovery performance. At the same time, when lead, aluminum, or copper is used to provide damping energy dissipation capacity, after performing its damping energy dissipation function under external load, lead, aluminum, or copper can recover to its mechanical properties before the load through automatic molecular crystallization. This gives the present invention good self-recovery performance and durability, avoiding frequent replacement of mild steel and other metal energy dissipators after external load, and greatly reducing the replacement frequency.

[0035] Example 2 like Figure 2 , Figure 3 , Figure 4 As shown, the composite metal damping device provided in this embodiment includes an upper linkage body 1 and a lower linkage body 2. Both the upper linkage body 1 and the lower linkage body 2 extend in the vertical direction and are located on the same vertical line. The upper linkage body is located above the lower linkage body. At least one damping component is also installed between the upper linkage body 1 and the lower linkage body 2. The thickness of the damping component extends in the horizontal direction.

[0036] The upper linkage (1) has a downwardly extending extension 11 at its mounting end. The extension 11 can be a steel material separately installed on the side wall or end face of the upper linkage 1, or it can be a reinforced concrete structure integral with the upper linkage 1, or it can be a composite structure of concrete and steel. Regardless of the structure of the extension 11, the extension 11 and the upper linkage 1 can be an integral structure or formed as one unit after being fixed by fasteners. The lower linkage 2 can be steel, or it can be a reinforced concrete structure integral with the upper linkage 1, or it can be a composite structure of concrete and steel.

[0037] The thickness of the lower linkage 2 is less than that of the upper linkage 1, and the mounting end of the lower linkage 2 is staggered with the extension 11. The height of the mounting end of the lower linkage 2 is greater than the height of the lower end of the extension 11. There is a certain gap between the extension 11 and the mounting end of the lower linkage 2. The damping component is installed in this gap. Specifically, one end of the damping component is fixed to the side of the extension 11, and the other end of the damping component is fixed to the side of the mounting end of the lower linkage 2.

[0038] When there is one damping component, one end of the damping component is fixed to the center of the extension section 11, and the other end of the damping component is located at the center of the side of the mounting end of the lower linkage body 2. When there are multiple damping components, the multiple damping components can be arranged in a rectangular array or in a quincunx pattern between the extension section 11 and the side of the mounting end of the lower linkage body 2. The specific number and specific arrangement of the damping components can be adjusted according to the actual situation.

[0039] Each damping assembly includes at least one damping element 3. When each damping assembly consists of one damping element 3, both ends of the damping element 3 are fixed to the extension portion 11 and the lower linkage body 2, respectively. When each damping assembly consists of multiple damping elements 3, the multiple damping elements 3 can be stacked sequentially to form a damping assembly. When the damping assembly is installed between the extension portion 11 and the side of the lower linkage body 2, the first damping element 3 in the damping assembly is fixed to the upper linkage body 1, and the last damping element 3 in the damping assembly is fixed to the lower linkage body 2. The damping element 3 includes two connecting plates, and a composite material body is fixed between the two connecting plates. The composite material body consists of alternating layers of flexible material and steel plate, which are vulcanized at high temperature to form a single unit. The flexible material provides good elastic recovery force.

[0040] In actual use, the number of damping elements 3 in each damping assembly can be adjusted according to the distance between the extension part 11 and the side of the mounting end of the lower linkage body 2, and the number of damping assemblies and the arrangement of multiple damping assemblies can be adjusted according to the required tonnage and mechanical parameters.

[0041] In some embodiments, the flexible material is one or more of ordinary rubber, high-damping rubber, viscoelastic material, and polyurethane. The flexible material can be selected according to the actual situation while ensuring the damping effect of the damping element 3.

[0042] In some embodiments, the composite material body is further provided with a central hole, which can be one or more, depending on the size and strength of the composite material body; at the same time, each central hole is filled with soft metal, which is cylindrical, and its two ends abut against two connecting plates respectively.

[0043] In some embodiments, the soft metal is lead, aluminum, or copper. Unlike mild steel and other metal energy dissipators, lead, aluminum, or copper will undergo irreversible elastoplastic deformation after performing their energy dissipation function and will need to be replaced. This gives the composite material as an energy dissipation element good self-recovery performance. At the same time, when lead, aluminum, or copper is used to provide damping energy dissipation capacity, after performing its damping energy dissipation function under external load, lead, aluminum, or copper can recover to its mechanical properties before the load through automatic molecular crystallization. This gives the present invention good self-recovery performance and durability, avoiding frequent replacement of mild steel and other metal energy dissipators after external load, and greatly reducing the replacement frequency.

[0044] Example 3 like Figure 6 , Figure 7 As shown, this embodiment provides a composite metal damping device, comprising an upper linkage body 1 and a lower linkage body 2. Both the upper linkage body 1 and the lower linkage body 2 extend in a vertical direction and are located on the same vertical line. The upper linkage body is located above the lower linkage body. At least one damping component is also installed between the upper linkage body 1 and the lower linkage body 2. The thickness of the damping component extends in a horizontal direction.

[0045] The upper linkage 1 has two downwardly extending extensions 11 at its mounting end, with a certain interval between them. Each extension 11 can be a steel component separately installed on the side wall or end face of the upper linkage 1. Alternatively, the extension 11 can be a reinforced concrete structure integral with the upper linkage 1, or a composite structure of concrete and steel. Regardless of the structure, the extension 11 and the upper linkage 1 can be an integral structure or formed as a single unit after being fixed together by fasteners. The lower linkage 2 can be made of steel, or it can be a reinforced concrete structure, or a composite structure of concrete and steel.

[0046] The thickness of the lower linkage 2 is less than the distance between the two extensions 11, and the mounting end of the lower linkage 2 is inserted between the two extensions 11. The height of the mounting end of the lower linkage 2 is greater than the height of the lower end of the extension 11. There is a certain gap between the extension 11 and the mounting end of the lower linkage 2, and the damping component is installed within this gap. Since the upper linkage 1 has two extensions 11, the multiple damping components in this embodiment need to be divided into two groups. The damping components in the two groups are respectively installed on opposite sides of the mounting end of the lower linkage 2. Specifically, one end of the damping component in each group is fixed to the side of the extension 11, and the other end is fixed to the side of the mounting end of the lower linkage 2.

[0047] When there is one damping component, one end of the damping component is located at the center of the extension section 11, and the other end of the damping component is located at the center of the side of the mounting end of the lower linkage body 2. When there are multiple damping components, the multiple damping components can be arranged in a rectangular array or in a quincunx pattern between the extension section 11 and the side of the mounting end of the lower linkage body 2. The specific number and specific arrangement of the damping components can be adjusted according to the actual situation.

[0048] Each damping assembly includes at least one damping element 3. When each damping assembly consists of one damping element 3, both ends of the damping element 3 are fixed to the extension portion 11 and the mounting end side of the lower linkage body 2, respectively. When each damping assembly consists of multiple damping elements 3, the multiple damping elements 3 can be stacked sequentially to form a damping assembly. When the damping assembly is installed between the extension portion 11 and the mounting end side of the lower linkage body 2, the first damping element 3 in the damping assembly is fixed to the extension portion 11, and the last damping element 3 in the damping assembly is fixed to the mounting end side of the lower linkage body 2. The damping element 3 includes two connecting plates, and a composite material body is fixed between the two connecting plates. The composite material body consists of alternating layers of flexible material and steel plate, which are vulcanized at high temperature to form a single unit. The flexible material provides good elastic recovery force.

[0049] In actual use, the number of damping elements 3 in each damping assembly can be adjusted according to the distance between the extension part 11 and the side of the mounting end of the lower linkage body 2, and the number of damping assemblies and the arrangement of multiple damping assemblies can be adjusted according to the required tonnage and mechanical parameters.

[0050] In some embodiments, the flexible material is one or more of ordinary rubber, high-damping rubber, viscoelastic material, and polyurethane. The flexible material can be selected according to the actual situation while ensuring the damping effect of the damping element 3.

[0051] In some embodiments, the composite material body is further provided with a central hole, which can be one or more, depending on the size and strength of the composite material body; at the same time, each central hole is filled with soft metal, which is cylindrical, and its two ends abut against two connecting plates respectively.

[0052] In some embodiments, the soft metal is lead, aluminum, or copper. Unlike mild steel and other metal energy dissipators, lead, aluminum, or copper will undergo irreversible elastoplastic deformation after performing their energy dissipation function and will need to be replaced. This gives the composite material as an energy dissipation element good self-recovery performance. At the same time, when lead, aluminum, or copper is used to provide damping energy dissipation capacity, after performing its damping energy dissipation function under external load, lead, aluminum, or copper can recover to its mechanical properties before the load through automatic molecular crystallization. This gives the present invention good self-recovery performance and durability, avoiding frequent replacement of mild steel and other metal energy dissipators after external load, and greatly reducing the replacement frequency.

[0053] Example 4 like Figure 8 , Figure 9 As shown, the composite metal damping device provided in this embodiment includes an upper linkage body 1 and a lower linkage body 2. Both the upper linkage body 1 and the lower linkage body 2 extend in the vertical direction and are located on the same vertical line. The upper linkage body is located above the lower linkage body. At least one damping component is also installed between the upper linkage body 1 and the lower linkage body 2. The thickness of the damping component extends in the horizontal direction.

[0054] The upper linkage 1 has two downwardly extending extensions 11 at its mounting end, with a certain gap between them. Extension 11 can be a steel component separately installed on the side wall or end face of the upper linkage 1, or it can be a reinforced concrete structure integral with the upper linkage 1, or it can be a composite structure of concrete and steel. Regardless of the structure, extension 11 and the upper linkage 1 can be an integral structure or formed by fixing with fasteners. Simultaneously, the lower linkage 2 has an upwardly extending extension 21 at its mounting end. Extension 21 can be a steel component separately installed on the side wall or end face of the lower linkage 2, or it can be a reinforced concrete structure integral with the lower linkage 2, or it can be a composite structure of concrete and steel. Regardless of the structure, extension 21 and the lower linkage 2 can be an integral structure or formed by fixing with fasteners.

[0055] The thickness of the second extension 21 is less than the distance between the two first extensions 11, and the second extension 21 is inserted between the two first extensions 11. The height of the upper end of the second extension 21 is greater than the height of the lower end of the first extension 11. There is a certain gap between the first extension 11 and the second extension 21, and the damping assembly is installed within this gap. Since the upper linkage 1 has two first extensions 11, the multiple damping assemblies in this embodiment need to be divided into two groups. The damping assemblies in the two groups are respectively installed on opposite sides of the second extension 21. Specifically, one end of the damping assembly in each group is fixed to the side of the first extension 11, and the other end is fixed to the side of the second extension 21.

[0056] When there is one damping component, one end of the damping component is located at the center of extension 11, and the other end of the damping component is located at the center of extension 21. When there are multiple damping components, the multiple damping components can be arranged in a rectangular array or in a quincunx pattern between extension 11 and extension 21. The specific number and specific arrangement of the damping components can be adjusted according to the actual situation.

[0057] Each damping assembly includes at least one damping element 3. When each damping assembly consists of one damping element 3, both ends of the damping element 3 are fixed to extension 11 and extension 21, respectively. When each damping assembly consists of multiple damping elements 3, the multiple damping elements 3 can be stacked sequentially to form a damping assembly. When the damping assembly is installed between extension 11 and extension 21, the first damping element 3 in the damping assembly is fixed to extension 11, and the last damping element 3 in the damping assembly is fixed to extension 21. The damping element 3 includes two connecting plates, and a composite material body is fixed between the two connecting plates. The composite material body consists of alternating layers of flexible material and steel plate, which are vulcanized at high temperature to form a single unit. The flexible material provides good elastic recovery force.

[0058] In actual use, the number of damping elements 3 in each damping assembly can be adjusted according to the distance between extension 11 and extension 21, and the number of damping assemblies and the arrangement of multiple damping assemblies can be adjusted according to the required tonnage and mechanical parameters.

[0059] In some embodiments, the flexible material is one or more of ordinary rubber, high-damping rubber, viscoelastic material, and polyurethane. The flexible material can be selected according to the actual situation while ensuring the damping effect of the damping element 3.

[0060] In some embodiments, the composite material body is further provided with a central hole, which can be one or more, depending on the size and strength of the composite material body; at the same time, each central hole is filled with soft metal, which is cylindrical, and its two ends abut against two connecting plates respectively.

[0061] In some embodiments, the soft metal is lead, aluminum, or copper. Unlike mild steel and other metal energy dissipators, lead, aluminum, or copper will undergo irreversible elastoplastic deformation after performing their energy dissipation function and will need to be replaced. This gives the composite material as an energy dissipation element good self-recovery performance. At the same time, when lead, aluminum, or copper is used to provide damping energy dissipation capacity, after performing its damping energy dissipation function under external load, lead, aluminum, or copper can recover to its mechanical properties before the load through automatic molecular crystallization. This gives the present invention good self-recovery performance and durability, avoiding frequent replacement of mild steel and other metal energy dissipators after external load, and greatly reducing the replacement frequency.
