Liquid Mass Damper
A Liquid Mass Damper is used to add damping to an oscillating, slender structure. Nowadays, engineers design structures to be as light and cost saving as possible. This makes these structure more vulnerable when it comes to natural influences such as water, wind and even earthquakes. To prevent or reduces the oscillation of a structure, a Liquid Mass Damper can be added. Flow Engineering has over 20 years of experience in the calculation, design and installation of Liquid Mass Dampers.
- Design of chimneys, stacks, flares
- Preventing dynamic problems at the design phase
- Analyzing and solving vibration problems in existing structures
Liquid Mass Damper: a lesser used damping solution
More often than not, when a structure suffers from oscillation that causes damage and unwanted movements – such as a swaying bridge – a Tuned Mass Damper is added to stabilize the structure, such as a bridge. But a Liquid Mass Damper is also a solution. A Tuned Mass Damper contains a mass that can oscillate horizontally or vertically and will oscillate in the opposite direction of the cross-wind loads or waves, while a Liquid Mass Damper uses a container that is filled with a mixture of water and glycol. The Liquid Mass Damper has, in contrast to a Tuned Mass Damper, no moving parts; the damping is fully provided by sloshing of the internal liquid. Because the Liquid Mass Damper is not only filled with water, but also with glycol, the liquid will not freeze.
