Tuned Mass Damper calculation
Flow Engineering can execute a Tuned Mass Damper calculation. We are specialised in the calculation, design and installation of Tuned Mass Dampers and have over 20 years of experience. Our Tuned Mass Damper solutions can be applied to slender structures such as flagpoles, bridges, chimneys and distillation columns and can prevent or reduce vibration problems and fatigue damage.
Other TMD Requirements
The TMD mass estimator above assumes a constant load acting upon the structure. However, the load amplitude often depends on the structure’s damping characteristics. For instance, in scenarios involving wind loads such as vortex shedding, the amplitude can decrease significantly with just a 1% increase in damping. Vortex shedding induces a non-linear negative aerodynamic damping. When the structural damping surpasses the aerodynamic damping, the amplitude reduces significantly. Note that the above calculator does not account for this effect.
Flow Engineering excels in analysing various vibration loads impacting structures. Our expertise allows us to accurately predict TMD system behaviour and ensure performance meets or exceeds expectations.
Designing a TMD system involves several practical considerations. For example, addressing friction in mechanical systems is crucial. When installing multiple TMDs or managing multiple vibration modes, additional care ensures a valid and safe design.
Designing a TMD system, aside from the basic theory (refer to Den Hartog’s “Mechanical Vibrations”), involves a complex process that cannot be condensed into a simple tutorial. Consequently, many prefer to outsource this process to specialized TMD manufacturers like Flow Engineering. We use dedicated software to design guaranteed TMD systems tailored to all types of structures. For more information about how we can assist with your project, please contact us.

Tuned Mass Damper calculation by Flow Engineering
Flow Engineering is not only a supplier specialised in the design, calculation and installation of Tuned Mass Dampers. We are also specialised in the preliminary design of chimneys, stacks, flares and other slender structures. When designing a slender structure, we can do a calculation to see if adding a Tuned Mass Damper is needed.
What does a Tuned Mass Damper do?
A Tuned Mass Damper is added to slender structures to prevent or reduce vibration problems that are caused by natural influences such as wind (vortex shedding), waves or earthquakes. When the structure starts to oscillate, the mass of the Tuned Mass Damper will oscillate in the opposite direction. It is a hydraulic component that turns the kinetic energy into thermal energy.
