Tuned Mass Dampers

Tuned mass dampers (TMDs) are a cost-effective and reliable solution for reducing vibrations in buildings, machinery and equipment.

There are various concepts for tuned mass dampers:

  • Passive systems
  • Semi-active systems
  • Active systems

Passive tuned mass dampers are a proven means of reducing unwanted vibrations. They consist of a mass, springs and dampers. Tuned to the structure to be settled, they reduce resonance vibrations.

Active and semi-active systems are always used when structural properties change or there is insufficient installation space for passive systems.


Areas of application

Tuned mass dampers as effective vibration protection for all applications

Undesired vibrations occur in almost all sectors and fields. Our engineers specialize in solving vibration problems and implementing the optimum tuned mass damper for every application.

Functional principle of passive tuned mass dampers

Modern structures with slender, cantilevered shapes usually have a low degree of structural damping, making them susceptible to vibrational excitation by wind and traffic loads as well as pedestrian movement. Tuned mass dampers increase the structural damping of structures and thus reduce resonance vibrations. They are tuned to the structure’s natural frequency to be reduced. They consist of stiffness (pendulum or springs), damping elements and a moving mass.

Functional principle of semi-active and active systems

Semi-active systems are characterized by the fact that the damping properties and the natural frequency of the tuned mass damper can be permanently adapted. An optimal effect is thus also achieved in buildings with variable properties.

Active systems consist of an actuator with reaction mass and a control unit with a sensor. Structural vibrations are detected constantly in order to generate damping forces, which in turn reduce the vibrations of the structure.
