A tuned mass damper is a device used to reduce and control structural vibration. Its working principle is to adjust the vibration frequency and damping ratio of the structure by adding a mass block above the structure and adjusting the damper to reduce structural vibration and improve effect on the seismic performance of structures.
Main uses include:
- Earthquake damping: Tuned mass dampers can be used for earthquake damping by adjusting the natural frequency of the structure and increasing the damping ratio of the structure, thereby reducing the impact of seismic forces on the structure and improving the structure’s seismic performance.
- Structural vibration reduction: Tuned mass dampers can be used to reduce the impact of external vibrations on the structure, such as wind-borne vibration or traffic vibration, effectively reducing the vibration amplitude of the structure and improving the stability and comfort of the structure.
- Structural energy saving: By adjusting the structural vibration frequency and damping ratio, the vibration energy loss of the structure can be reduced, thereby reducing the energy consumption of the structure and improving the energy saving effect of the structure.
In short, tuned mass dampers have broad application prospects in construction engineering, bridge engineering and other engineering fields, and can effectively improve the seismic performance and vibration reduction effect of structures.
