Active Damping Devices
Active Damping Devices deliver active vibration control for highly precise and sensitive equipment, especially in applications such as structural active damping.
Description
Improve your most sensitive equipment with Micromega Dynamics Active Damping Devices.
When traditional passive or active isolation platforms fall short, and local or global resonances threaten your equipment precision, our Active Damping Devices step in to restore it.
They benefit sophisticated equipment such as microscopes, inspection devices, imaging systems and polishing machines, where optimal performance is paramount and the existing isolation lacks stiffness or faces perturbations on the isolated part.
By introducing structural active damping into unwanted mechanical resonances, these active vibration control devices achieve up to 15% structural damping without major redesign. Unlike passive dampers, they are lighter and stay insensitive to changes in the supporting structure dynamics.
Understanding active vibration control
Active vibration control, also called structural active damping, mitigates vibrations and resonances by actively introducing damping forces. Damping dissipates energy in a vibrating system, which is key to controlling vibrations and preventing resonance related issues.
Sensors detect vibrations or resonances in the structure and send signals to the damping system, which generates forces to counteract them. This is typically done with actuators, such as hydraulic or electromagnetic devices, that exert forces on the structure.
Key benefits
Non-intrusive
No structural modification. The device does not degrade the static strength or the stiffness of the structure.
Additive
The more devices installed, the greater the vibration reduction.
Robust to resonance shifts
The ADD performances are not affected by changes in the resonance frequencies.
No tuning required
An ADD does not need to be tuned to the respective target resonance.
Lighter, better performing
Compared to a passive Tuned Mass Damper, an ADD is usually lighter and more efficient, backed by more than 20 years of experience.
Typical use
Structural active damping finds its stride across a spectrum of applications where precise management of dynamic forces is imperative:
- Structural vibration reduction of isolated machines for performance improvement (microlithography, microscope, chip manufacturing or inspection machines, etc.)
- Machine tool chatter reduction
- Improved overlay of printing process
- Paper mill roll barring avoidance
