Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically to an energy-consuming composite metal viscoelastic damper structure. Background Technology

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. Various types of dampers (or shock absorbers) have long been used in aerospace, aviation, military, artillery, and automotive industries to reduce vibration and dissipate energy. In seismic instruments, dampers are used to absorb the inherent vibration energy of a vibrating system. Their damping force is generally proportional to the velocity of the vibrating system. Dampers play an important role in compensating for small frictions and air resistance in the vibration pickup pendulum system and improving frequency response. Existing dampers expand and contract within their designed stroke range during operation. Furthermore, dampers are subject to vibration and other external factors during operation, making their expansion and contraction paths highly variable and prone to deviation. Long-term use increases the probability of damper deformation, thus affecting its service life and efficiency. Therefore, designing an energy-dissipating composite metallic viscoelastic damper structure is crucial. For example:

[0003] A composite metal damper, disclosed in Chinese patent application CN212376064U, includes two axially extending connecting end plates; it also includes an energy-dissipating core plate, a first intermediate plate, a second intermediate plate, a friction plate, and an outer constraint plate extending radially between the two connecting end plates. By cleverly combining the metal damper with a friction damper, the outer constraint plate of the friction damper is used as a constraint member for the energy-dissipating core plate of the metal damper. The outer constraint plates on both sides are pre-tightened with bolts to constrain the out-of-plane deformation of the energy-dissipating core plate, which not only enhances the performance of the metal damper but also avoids the damage to the energy-dissipating core plate caused by the traditional method of welding stiffening ribs. By utilizing the hysteresis characteristics of the friction damper, the second stiffness of the metal damper is effectively reduced, enabling the metal damper to meet the requirements of seismic design.

[0004] However, some energy-dissipating composite metal viscoelastic damper structures are not easy to assemble quickly, and at the same time, they are not easy to maintain stable performance during long-term use.

[0005] Therefore, those skilled in the art urgently need to design an energy-consuming composite metal viscoelastic damper structure. Utility Model Content

[0032] To address the problems existing in the prior art, this utility model provides an energy-dissipating composite metal viscoelastic damper structure. This energy-dissipating composite metal viscoelastic damper structure includes an intermediate plate and a friction assembly disposed on the outer side of the intermediate plate, as detailed below:

[0033] 1-Intermediate Plate

[0034] The aforementioned intermediate plate has a limiting groove inside, and an external hexagonal connector is installed inside the intermediate plate. An external hexagonal connector ring is provided on the outside of the external hexagonal connector. The external hexagonal connector is inserted through the mounting groove, positioning groove, and limiting groove respectively, and the external hexagonal connector ring is screwed on the outermost side of the external hexagonal connector. This allows the support frame of the energy-dissipating composite metal viscoelastic damper structure to be connected to both the upper friction pair and the lower elastic group, facilitating the rapid assembly of the energy-dissipating composite metal viscoelastic damper structure.

[0035] In some examples, the aforementioned hexagonal connector passes through the interior of the limiting groove, and the hexagonal connector and the hexagonal ring are threaded together. Inserting the hexagonal connector through the interior of the energy-dissipating composite metal viscoelastic damper structure facilitates the connection and assembly of components within the energy-dissipating composite metal viscoelastic damper structure.

[0036] 2-Friction Assembly

[0037] The aforementioned friction assembly includes a stainless steel plate disposed on the outer side of the intermediate plate, a friction plate body disposed on the outer side of the stainless steel plate, a friction base plate mounted on the outer side of the friction plate body, a positioning groove formed inside the friction base plate, a disc spring body disposed on the outer side of the friction base plate, a pressure plate mounted on the inner side of the disc spring body, an installation groove formed inside the pressure plate, a first rubber body disposed on the left side of the intermediate plate, a first stiffening plate mounted inside the first rubber body, a first stiffening plate mounted on the left side of the first rubber body, a second rubber body disposed on the right side of the intermediate plate, a second stiffening plate mounted inside the second rubber body, and a second side plate disposed on the right side of the second rubber body. When an earthquake occurs, both the first and second side plates are subjected to inward pressure. The first and second rubber bodies are compressed first, and the horizontal distance between the two adjacent sets of first stiffening plates and the two adjacent sets of second stiffening plates changes. The pressure plate applies inward pressure to the disc spring body, and the disc spring body begins to undergo elastic deformation. The horizontal distance between the pressure plates on the left and right sides and the middle plate changes. At the same time, the friction base plate rubs against the friction plate body, and kinetic energy is converted into frictional force. This allows the structure's energy to be effectively consumed under strong dynamic forces such as earthquakes, reducing the vibration amplitude of the structure and protecting the safety of the structure.

[0038] In some examples, the stainless steel is arranged symmetrically about the centerline of the intermediate plate, and the length of the stainless steel is longer than the length of the friction plate body. By adjusting parameters such as the pressure and friction coefficient between the friction plate body and the friction base plate, different damping forces can be customized according to the specific structural requirements, thereby optimizing the vibration reduction effect of the structure.

[0039] In some examples, the aforementioned friction plate bodies are arranged symmetrically about the center line of the friction base plate. Two sets of friction plate bodies are provided on the friction base plate, and each set of friction plate bodies corresponds to a set of stainless steel.

[0040] In some examples, the disc spring body is engaged with the pressure plate, and the longitudinal section of the pressure plate is T-shaped. After the pressure plate engages with the disc spring body, during an earthquake, the pressure plate will exert pressure on the disc spring body, causing the disc spring body to undergo elastic deformation.

[0041] In some examples, the aforementioned pressure plates are arranged symmetrically about the center line of the external hexagonal connector, and the external hexagonal connector passes through the mounting groove inside the pressure plate. The external hexagonal connector, passing through the mounting groove, connects to the pressure plate, simplifying the structure of the energy-dissipating composite metal viscoelastic damper and reducing costs.

[0042] In some examples, the first rubber body is bonded to both the first side plate and the middle plate, and the first stiffening plates are evenly spaced on the first rubber body. After the first rubber body is bonded to the middle plate, the first rubber body has good durability and can maintain stable performance during long-term use.

[0043] In some examples, the second rubber body is fitted and connected to both the intermediate plate and the second side plate, and the second stiffening plates are evenly spaced on the second rubber body. The second rubber body is made of the same material as the first rubber body, so that durable material is provided on both sides of the intermediate plate.
