Abstract:
An active system for isolating vibrations, comprising:at least one first vibration-isolating device, arranged between a load and a standing surface, for at least partially decoupling the static and dynamic forces acting between the load and the standing surface, said first vibration-isolating device comprising a passively isolating coupling element for mechanically decoupling the static and dynamic forces including a natural frequency; at least one second vibration-isolating device, assigned to the load, for imparting control forces to the load for actively damping the substantially decoupled dynamic forces, said second vibration-isolating device comprising a coupling element for dynamically coupling said second vibration-isolating device to the load and the first isolating device, said coupling element including a natural frequency; means for tuning the control forces of the second vibration-isolating device and the natural frequencies, wherein the control forces of the second vibration-isolating device and the natural frequencies are determined by means of characteristic curves describing the functional dependency of the control forces to the natural frequencies of the passively isolating coupling element and the ratio of the natural frequencies.
