TMD Vibration Control Device 【For wind vibration, resonance, and earthquake countermeasures!】
TMD type
It demonstrates high vibration control effectiveness in structures that are difficult to dampen, such as high-rise buildings and bridges!
Buildings/devices shaking is a problem. You want to take measures against vibrations but don’t know how… This is for you! Gelb Japan, with proven results in Europe and Japan, will propose the optimal device. What is TMD? It stands for Tuned Mass Damper. It suppresses vibrations of the target object by attaching a weight (mass) to the device. It is effective in both vertical and horizontal directions. As a passive type damper, it does not require power or other energy for operation, providing stable performance. It is effective for structures like cantilever balconies, where it is difficult to increase rigidity. Gelb's TMD has been used in the Millennium Bridge in London, UK, and has numerous achievements worldwide. (Target examples: bridges, stairs, stadium roofs, chimneys, masts, etc.)

basic information
The TMD that operates in the vertical and horizontal directions is a passive type damper and consists of the following three elements: [Elements] - Spring or pendulum - Vibrating mass - Viscous damper (Viscodamper) At Gelb, we design and propose the optimal TMD according to individual requirements.

Applications/Examples of results
Structures with large widths, such as bridges, stairs, and stadium roofs, as well as slender and tall structures like chimneys, antennas, and masts, are known to easily resonate with the natural frequency of buildings. Due to their dimensions, such structures have low natural frequencies and damping ratios, which can lead to vibrations caused by wind, human movement, other machinery, or earthquakes. By using the tuned mass damper (TMD) from GERB, it is possible to easily reduce such vibrations.
