Platform Dampens Vibrations in All Spatial Directions
- Created on Monday, 31 March 2014
When scientists wish to protect sensitive measuring devices from interference, they turn to active damping or, more specifically, an isolation platform. Each of the platform's four integrated swivel-mount modules contains a sensor that measures any vibrations in all three directions and an actuator that counterbalances them in three dimensions.
Researchers have now come up with the first vibration control table of its kind to incorporate function-integrated components. Instead of using non-adjoining sensors and actuators that are built into the table legs, the functional elements are integrated directly into the platform's mounting modules, making the vibration control table considerably more streamlined and cheaper to produce. And practical tests have already shown that the system works. The table dampens interfering vibrations just as well as its traditional counterparts.
Conventional vibration control tables have mounts that are fitted with readymade actuators and sensors that work independently of the table itself. These functional elements are combined beforehand within the mounts themselves. Interacting components carry out the same function as actuators. Neither the actuator nor the springs could work on their own — they can only work together to protect the table.
