application field

In the Product Catalog, tuned mass damper (TMD) is listed in the vibration control category and is often used in combination with structural wind vibration control and comfort control; Typically used for tuning and dissipating vibrations caused by wind loads or pedestrian excitations in super tall buildings, high-rise structures, large-span floor systems, and pedestrian bridges.

Explanation: Detailed descriptions related to TMD in the directory can be found in items such as "Active Shock Absorbers (AMD)" (such as wind resistant examples for super high-rise buildings). For engineering applications, please refer to the design documents and company technical data.

working principle

The tuned mass damper adds a mass spring damping subsystem to the main structure, tuning the subsystem frequency to the sensitive mode of the structure; When the external excitation frequency approaches this mode, the subsystem resonates and absorbs and dissipates vibration energy, thereby reducing the response of the main structure.
