Abstract: An active vibration absorber is provided for damping vibrations of a cantilevered portion of a support structure. The vibration absorber comprises a mass, a drive and a control device. The mass is coupled without using a spring and through the drive to a fastening means for fastening the drive to the support structure, so that upon a movement of the mass relative to the fastening means an inertial force caused by this movement is directly transmitted through the drive to the fastening means. The control device comprising a motion sensor is adapted to control the drive in function of a signal from the motion sensor. The active vibration absorber is designed to damp especially low-frequency vibrating structures including more than one mass-spring element so that the vibration amplitude thereof is significantly reduced.
Abstract: The invention relates to a stationary vibration isolation system and to a method for controlling such a system which comprises a damper effective in a horizontal direction which includes a fluid of variable viscosity.
Abstract: The invention relates to a vibration isolator that includes a coil spring. In a horizontal direction, the coil spring is stiffly coupled to the base or to the load to be isolated.
Abstract: A vibration isolation system which comprises a support divided into a plurality of rigid sections on which a displaceable stage is arranged. The sections are arranged on pneumatic bearings, and the pneumatic bearings of the individual sections are controlled independently from each other and based on the position of the displaceable stage.

Abstract: Method and arrangement for oscillation isolation by means of an air bearing. The electropneumatic valves (4) for the compressed-air supply to the air bearing are subjected to a dither signal. This causes additional vibration of the mass 1 to be isolated. A compensation signal transmitter (12) ensures that additional vibration of the mass (1) is suppressed, by controlling actuators (10). Overall, hysteresis effects are avoided in the control of the compressed-air flow.
Abstract: The invention relates to an active vibration isolation system which detects structural vibration of the mass to be isolated via a sensor and also takes account of these disturbance variables.

These control devices (20, 30, 40) are subordinate to an overall control device (50), which acts as a host system, via a real-time bus (60).
Abstract: An active vibration absorber is provided for damping vibrations of a cantilevered portion of a support structure. The vibration absorber comprises a mass, wherein the mass is coupled without using a spring and through a drive that is controlled by a control device of the vibration absorber to a fastening means for fastening the drive to a support structure to be damped, so that upon a movement of the mass relative to the fastening means an inertial force caused by this movement is directly transmitted through the drive to the fastening means, and wherein the control device comprises a motion sensor and the control device is adapted to control the drive in function of the signals from the motion sensor. The active vibration isolator has a purpose of damping especially low-frequency vibrating structures including more than one mass-spring element so that the vibration amplitude thereof is significantly reduced.
