Manufacture, installation, and maintenance of damper systems

A Tuned Mass Damper (TMD) is a device designed to add damping to a structure for a specific frequency. The extra damping will reduce the movement of the structure to an acceptable level.

A tuned mass damper contains a mass that is able to oscillate in horizontal or vertical direction. The oscillation frequency of the mass can be tuned using springs, suspension bars or ball transfers. When the structure starts to oscillate the mass of the TMD  will oscillate in opposite direction, a frictional or hydraulic component connected between the structure and mass turns the kinetic energy into thermal energy.

The design of an TMD depends on the oscillation frequency and mass of the structure, direction of the movements (horizontal or vertical) and available space.

More information concerning our TMD systems can be found in the Technical information and products brochure.


Flow Engineering has more than 20 year experience in the calculation, designing and installation of TMD systems. Our TMD systems are applied to bridges, flagpoles, chimneys, distillation columns and other slender structures.

Our Tunes Mass Damper solutions have proven themselves in practice. The solutions we offer ensure the reduction of the vibration to an acceptable level and prevent fatigue damage.
