Working Principle
|
The working principle of a friction damper is to use frictional force to dissipate energy, thereby suppressing vibration and impact. When the building structure is subjected to external excitations such as earthquakes, relative motion occurs between the damping elements in the damper and the external clamping elements. At this point, the friction damping layer generates frictional force on the contact surface, which is proportional to the relative velocity between the damping element and the outer clamping element, and also related to the positive pressure on the contact surface. As the relative motion continues, frictional force continues to do work, converting vibrational energy into thermal energy and dissipating it into the surrounding environment. In this way, the impact of external stimuli such as earthquakes on building structures is effectively weakened. The energy dissipation capacity of friction dampers is related to the structural vibration velocity, so they can produce different energy dissipation effects under different seismic intensities. When the earthquake intensity is low, the energy dissipation effect is weak; When the earthquake intensity is high, the energy dissipation effect is enhanced, thereby achieving the goal of adaptive damping. In addition, friction dampers are usually composed of a middle steel plate, two side steel plates, and friction materials between the steel plates. Friction is generated by the relative sliding between the middle steel plate and the friction material, converting the vibration energy of the building into thermal energy, thereby achieving the goal of reducing structural vibration |

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
|
Friction dampers are mainly used in various fields such as building structures and industrial sectors. Friction dampers are key equipment for improving the overall stability of building structures, especially in high-rise buildings and large-span bridges. They can convert some kinetic energy into thermal energy or other forms of energy loss through internal friction mechanisms under external forces such as earthquakes, thereby reducing the vibration amplitude of the structure and protecting the building from serious damage. In addition, friction dampers also play an important role in the industrial field. For example, installing such dampers in mechanical equipment can effectively reduce vibration noise caused by unstable operation; Friction dampers can be used in pipeline systems to mitigate pressure fluctuations caused by medium flow. Friction dampers are also widely used in industries such as aerospace and aviation for vibration reduction and energy dissipation. |
