Abstract
An active system for isolating vibrations includes: at least one first vibratio-isolating device, arranged between a load and a sstanding surface, for at least partially decoupling the static and dynamic forces acting between the load and the standing surface, the first vibration-isolating device includes 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, the second fibratio-isolating device including a coupling element for dynamically coupling said second vibration-isolating device to the load and the first isolating device<the coupling element including a natural frequency; means for tuning the control forces of the second vibratio-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 d…
