GET A QUOTEThe friction damper mainly includes the middle steel plate, the two outer steel plates and the friction material between the steel plates. The friction damper is the friction force generated by the relative slip between the intermediate steel plate and the friction material, which converts the vibration energy of the building into heat energy, so as to reduce the vibration response of the structure.
Features:
1. The hysteresis curve is basically rectangular, and the shock absorption effect is obvious; 2. The speed correlation and displacement correlation are small, and the performance is stable;
3. Good cycle durability, no need for post-maintenance;
4. Damping force can also be generated under small displacement;
5. The earthquake will not be damaged, so it does not need to be replaced;
6. The mechanical model is simple, and the analysis and design of structural vibration reduction are simple and easy to implement;
7. Simple structure and low cost.
Working Principle:
Friction dampers are used in engineering because of their simple construction, stable performance, and high damping force. For structures with friction dampers, under normal service loads, the friction dampers provide additional stiffness to the structure without slipping; under moderate to large earthquakes, the friction dampers provide additional damping to the structure by producing frictional slip work to absorb the energy input from the earthquakes, thereby reducing the structural response.
