Overview
Principles of Construction
Viscoelastic damper is a type of damper that utilizes viscoelastic materials to absorb vibration energy. It is composed of steel plates and viscoelastic materials bonded together, similar to a sandwich structure. The relative motion of the steel plates drives the deformation of the viscoelastic materials to generate energy dissipation. It is a composite damper that combines displacement and velocity types.
Under external force, the deformation of viscoelastic dampers is the sum of the deformation of viscoelastic damping materials, steel plates, and adhesives. Its damping force is related to velocity and displacement, and has three types of load deformation hysteresis curves: linear, deformation softening, and deformation hardening.
This type of damper has multiple advantages, such as not using liquid, no problem of liquid leakage, and no need for regular maintenance during use; After being reliably connected to the building structure, it can effectively dissipate small amplitude wind vibrations; During an earthquake, it can meet the energy dissipation requirements under large deformations while also contributing some stiffness; The hysteresis curve is full and can be easily modeled using general software nonlinear elements to obtain high-precision results.
In addition, viscoelastic dampers also have high energy dissipation capacity and can effectively reduce the vibration response of structures under external excitations such as earthquakes and wind loads by performing good energy dissipation under small displacements. At the same time, its mechanical performance is stable and reliable, with strong self recovery ability, and can maintain effective shock absorption effect for a long time.
Product advantages
1,The product advantages of viscoelastic dampers mainly lie in providing additional damping to the structure without changing the natural vibration period, good economy, strong applicability, and low maintenance costs.
2,The main advantage of viscoelastic dampers is that they only provide additional damping to the structure without providing additional stiffness, thus not changing the natural vibration period of the structure. This makes them widely applicable in various structural vibration control applications. At the same time, it has good economy and can reduce usage costs while ensuring performance. In addition, viscoelastic dampers have strong applicability and can be applied to various civil engineering structures, such as wind resistance and improving building comfort. They also have certain applications in seismic engineering.
3,In addition, viscoelastic dampers use viscoelastic materials such as rubber and polymers, which can maintain stable performance over a wide temperature range and have good aging resistance, thereby ensuring the long-term stability and reliability of the damper.

The working principle of viscoelastic dampers is to dampen the transmission of vibration energy through the combined action of viscoelastic and frictional elements. When a structure vibrates, viscoelastic elements will exert a damping effect on the structure, thereby dampening the transmission of vibration energy; At the same time, frictional elements will generate a certain resistance to the displacement of the structure, limiting the amplitude of the structure and thus playing a role in shock absorption. Specifically, viscoelastic dampers utilize the viscoelastic properties of materials to absorb seismic energy through shear deformation of viscoelastic materials and convert it into thermal energy for dissipation, thereby reducing the vibration amplitude of the structure and achieving the effect of shock absorption. |

Product Structure
|
Friction dampers are usually composed of upper and lower pressure plates, polymer composite friction materials, friction steel plates, and fastening bolts. Among them, friction plates and friction materials are the core components of dampers, usually made of high-strength and wear-resistant materials, used to generate relative motion under earthquake or wind force, thereby consuming energy. In addition, pre tightening devices (such as fastening bolts, disc springs, etc.) are used to apply pre tightening force to the friction plate, ensuring its tight fit, so as to immediately generate frictional force under external excitation. The supporting structure is used to fix and support these components, ensuring that the damper remains stable during operation |

Applications
|
Viscoelastic dampers are sandwich like structures formed by bonding steel plates and viscoelastic materials. Specifically, it is composed of alternating stacking and bonding of viscoelastic damping material and constrained steel plates. In addition to the viscoelastic damping material, there are also constrained steel plates and adhesive layers. The common construction forms of viscoelastic dampers include wall plate type, axial type, rotary type, etc. This structure enables the viscoelastic damper to undergo shear deformation of the viscoelastic material due to the relative movement of the steel plate when subjected to external forces, thereby dissipating energy and protecting the main structure. |
