A damper is a device used to absorb shock and control mechanical motion. It mainly reduces vibration and impact by absorbing and converting kinetic energy. Dampers can be divided into various types according to their working principles and structural characteristics. Several common dampers will be described in detail below.
The first is a friction damper. friction damperA device used to control vibrations in building structures. It uses the principle of friction to suppress the vibration of the structure, which can effectively improve the stability and earthquake resistance of the building.By adjusting the friction of the friction plate, the vibration of the building structure can be effectively controlled, the risk of resonance is reduced, and the seismic resistance of the building is improved.
The second type is a metal composite damper, which is a structural damper usually composed of metal materials and damping materials. Its functions mainly include the following aspects: Shock absorption: Metal composite dampers can absorb and disperse the vibration and impact energy of the structure, thereby reducing the vibration amplitude and fluctuation of the structure and protecting the safety and stability of the structure. Energy consumption effect: Metal composite dampers convert vibration or impact energy into heat energy through the elastic deformation of the structure and the loss of metal materials, thereby dissipating energy and reducing the vibration intensity of the structure. Adjustment and control function: The damping characteristics of metal composite dampers can control and adjust structural vibration through the selection of materials and adjustment of design parameters, and improve the dynamic performance of the structure. Enhanced seismic resistance: Metal composite dampers can increase the seismic resistance and shock absorption capacity of the structure, allowing the structure to effectively resist vibration under the action of external forces such as earthquakes, and reduce structural damage and damage. Metal composite dampers mainly control and eliminate structural vibration and impact through shock absorption, energy dissipation, adjustment and control, and improve the structure’s seismic resistance and stability. Its application in engineering structures can effectively reduce the damage and damage caused by vibration to the structure and protect the safe and reliable operation of the structure.
The third type is viscous damper, a device used to reduce vibration and impact. Its functions mainly include the following aspects: Shock absorption: Viscous damper can absorb and disperse vibration and impact energy, thereby reducing the damage of the structure or equipment. Vibration and impact amplitude, protecting the safety and stability of structures or equipment. Slow down the movement speed: The viscous resistance of the oil inside the viscous damper can slow down the movement speed of the structure or equipment and generate damping force during the movement, thereby effectively reducing the speed and impact strength of the movement. Energy dissipation: Viscous dampers convert vibration or impact energy into heat energy, and achieve energy dissipation through the friction and flow of materials inside the viscous damper, thereby reducing the vibration and impact amplitude of the structure or equipment. Adjustment and control function: The damping characteristics of the viscous damper can control and adjust the vibration and impact of the structure or equipment by adjusting the viscosity of the oil or adjusting the design parameters of the damper. Viscous dampers mainly control and eliminate vibration and impact through shock absorption, deceleration, energy dissipation and control and adjustment, and improve the performance and reliability of structures or equipment.
The fourth type is that the tuned mass damper is widely used in engineering structures to suppress resonance: the tuned mass damper can effectively suppress the resonance phenomenon of the structure, prevent the structure from excessive amplitude or destructive vibration under external force excitation, and improve the structure stability and security. Reduce the dynamic response of the structure: The tuned mass damper can adjust the natural frequency of the system to make the dynamic response of the structure smaller under external force excitation and reduce the vibration level of the structure. Absorb vibration energy: Tuned mass dampers can absorb and convert the vibration energy of the structure into other forms of energy (such as heat energy), thereby reducing the dynamic response of the structure and protecting structures and equipment. Improve the fatigue life of the structure: Tuned mass dampers can reduce the stress and deformation of the structure, reduce the fatigue damage rate of the structure, and extend the service life of the structure. In short, tuned mass dampers can effectively control the vibration response of the structure, improve the dynamic characteristics of the structure, and improve the safety and reliability of the structure.
The fifth type is metal yield damper, which mainly absorbs and dissipates energy through the elastic deformation of metal to reduce structural vibration. Its main functions include shock absorption: when the structure is subject to earthquakes, wind loads or other external excitations, metal yield dampers can absorb the vibration energy of the structure, thereby reducing the amplitude and time of structural vibration, and reducing the risk of structural damage and collapse. Vibration reduction effect: The metal yield damper has a good vibration reduction effect on the low-frequency vibration of the structure, which can effectively reduce the resonance phenomenon of the structure and avoid damage to the structure caused by resonance. Energy absorption: When the structure is subjected to a large vibration force, the metal yield damper can absorb and dissipate energy through the yielding and plastic deformation process of the metal, protecting the structure from damage. Increase the stability of the structure: Metal yield dampers can improve the seismic and wind-resistant performance of the structure and increase the stability and safety of the structure. Reduce the dynamic response of the structure: Metal yield dampers can reduce the dynamic response of the structure by absorbing and dissipating vibration energy, reduce the response of the structure to excitations such as earthquakes, and improve the stability and safety of the structure. Metal yield dampers mainly improve the stability and safety of the structure through shock absorption, vibration reduction, energy absorption, etc., reduce the vibration response of the structure, and protect the structure from damage by external excitations.
The sixth type is the coupling beam damper. The coupling beam damper is a device installed on the building structure. Its function is to reduce the transmission of shock and vibration by providing damping force. It can be used in various types of buildings, including residential buildings, commercial buildings and large infrastructure such as bridges and towers.
In short, dampers can be divided into various types according to their working principles and structural characteristics, including friction dampers, metal composite dampers, viscous dampers, tuned mass dampers, metal yield dampers, etc. They play different roles in their respective fields and are very important for shock absorption and control of mechanical movements. In practical applications, people can choose the appropriate damper type according to specific needs to ensure the stable operation, safety and reliability of mechanical equipment.
