1TS-140 - Active Vibration Isolation System

Active Vibration Isolation System
Active Vibration Isolation System
The isolation of the 1TS-140 begins at 0,7 Hz,
increasing rapidly to 40 dB beyond 10 Hz
The lack of any low frequency resonance means
much better performance than with common passive
damping approaches
The inherent stiffness of the 1TS-140 imparts
excellent directional + positional stability
The outstanding isolation performance of the 1TS-140
includes all six linear and rotational vibration modes

Active isolation systems offer a solution, which combines stiffness with a very short settling time. The most useful active systems employ inertial velocity in a feedback loop. (Inertial velocity can be measured for example by integration the signal from an accelerometer). A signal proportional to inertial velocity is very similar to a viscous damping force, but with the very important difference that the damping is relative to an inertial plane. So in contrast to the passive system, by increasing the damping, the system becomes ‘glued’ to the inertial plane which by definition means the system is isolated from the environment.
