Active damping isolator的概况 -
In what situations are active damping isolator used?
Do you have highly accurate, environmentally-sensitive equipment such asmicroscopes, inspection equipment, imaging systems, or polishers, and theuse of active or passive isolation platforms does not meet your needs?
It may be that local/global resonance reduces the performance of the isolatedsystem because it is not stiff enough, or because the vibration source is locatedon the component being isolated.
Based on such cases, our active damping devices can provide a solution byintroducing structural damping in most unwanted mechanical resonances.Up to 15% structural damping can be achieved without redesign. Comparedwith the passive damping, the active damping is lighter and insensitive to thedynamic changes of the support structure.➤ Reduce structural vibrations of isolated machines (such as photolithography, microscopes, chip manufacturing, or inspection machines)
Principle
The active damper is based on the following principle: accelerating the
suspended mass generates a reaction force on the supporting structure.
Embedded sensors monitor the vibrations of the supporting structure.
Sensor readings are sent to an external feedback controller, which drives
the internal electromagnetic actuator of the active damping device.
Classic Uses
➤ Improve stabilization time of moving cameras and optical devices through structural damping
➤ Reduce machine tool chatter (damping in the machine structure can prevent vibrations)
➤ Improve registration in printing processes
➤ Prevent collisions of rollers in paper mills
➤ Enhance pointing accuracy of systems with vibrating bases
➤ Reduce emission of structural noise
