Passive Damping Devices
Address excessive vibrations with Micromega Dynamics Passive Damping Systems. Tuned Mass Dampers (TMD) and Tuned Mass Absorbers (TMA) provide a simple and effective solution to reduce them.
Description
Experience seamless vibration reduction with the Micromega Dynamics Passive Damping System.
TMA_TMD_EN-v1p2 brochureTuned Mass Absorbers (TMA) and Tuned Mass Dampers (TMD) are mechanical resonant devices that suppress vibrations at the source. Properly tuned and installed on a machine or a structure, they draw the vibrational energy away from it and dissipate it internally, reducing its motion.
TMA and TMD have been successfully implemented on large water pumps, rotary no-break systems, chemical reactors, wind turbine gearboxes and scroll compressors.
Tuned Mass Damper
TMDs address frequency non stationary harmonic vibration; they are used on structures subjected to shocks, when rotation speed varies, with a transient speed running over mechanical resonances, or for wideband and random excitation.
TMDs with magnetic booster allow for much higher internal damping, even at high frequencies, as required for systems with optimal damping.
Tuned Mass Absorber
TMAs address stationary harmonic vibration; they are used when the excitation frequency or rotation speed is fixed.
Features
Non-intrusive
No redesign, no structural modification. Simply attached, it damps vibrations without affecting static strength, stiffness or normal operation.
Additive
The more devices installed, the greater the vibration reduction. Performance scales with each unit added.
100% passive
No power supply, no electronics, no maintenance. It runs entirely on mechanical resonance.
Typical use
Rotating machinery
- Whenever alignment and balancing of the rotating equipment has been performed but the vibration level is still too high
- Excessive structural vibration excitation during ramp up or slow down (stirring machine, flywheel, etc.)
Mechanical structures
- Whenever isolating the structure from excitations coming from the ground is not possible or does not give good results
- Whenever increasing the system stiffness is not an option
- Piping vibration
Inspection machines, robots, etc.
- Time to stabilization improvement when fast decelerations cause structural oscillations (robot arm, inspection machine with moving camera, etc.)
Wind turbine tonalities
- Wind turbine gear box vibration and noise emission reduction
