Tuned Mass Dampers (TMD) and Tuned Mass Absorbers (TMA) offer a simple and effective solution for reducing vibrations.
They are perfect for reducing vibrations in rotating machinery when alignment and balancing cannot achieve adequate results, as well as for vibration/noise emissions from wind turbine gearboxes.
These passive vibration dampers TMD/TMA prevent excessive structural vibration excitation during acceleration or deceleration (agitators, flywheels, etc.) and improve stabilization time when decelerations cause structural oscillations (e.g., robot arms, inspection machines with mobile cameras, etc.).
TMA handles static harmonic vibrations, while TMD handles non-stationary harmonic vibrations.
The vibration damping effect of a TMD is typically lower than that of a TMA, but it is global, whereas the effect of a TMA is more significant but limited to a frequency band.
Equipped with damped mechanical oscillators, the TMD damper is ideal for replacing lightly damped resonance with two damped resonances.
The damping effect directly depends on the mass ratio between the target structure's mass and the TMD mass.
Tuned Mass Absorbers (TMA) consist of undamped mechanical oscillators. This damper absorbs vibrations in a frequency band around its own resonant frequency.
Vibration reduction with a TMD or TMA is a non-intrusive process. No structural modification is required.
The device does not degrade the static strength or stiffness of the target structure.
Performance with TMD or TMA is additive, so the more devices you attach to the structure or machine, the greater the vibration reduction achieved.
The TMD is equipped with a Magnetic Booster that allows for optimal damping of the device by increasing its effective damping and/or reducing the size of the damping system.
TMA or TMD are fully passive and require no power supply; they simply need to be tuned to the target resonance or excitation frequency.
