<p>The invention relates to an active element (10) for reducing the vibrations of components and in particular aircraft components. Said element comprises a support structure (11, 12) for fixing a first component to a second component, in addition to an actuator unit (13), which is mechanically coupled to the support structure (11, 12), in order to subject the support structure (11, 12) to variable forces. A regulator controls the actuator unit (13), based on a sensor signal, in order to minimise the transmission of unwanted vibrations along a transmission path through the support structure (11, 12). Said support structure (11, 12) can be regulated by the actuator unit (13) in three degrees of freedom to counteract the transmission of the unwanted vibrations. The support structure is configured by a first support plate (11), a parallel second support plate (12) and several actuators that form the actuator unit (13) and are located between the two plates. The inventive active element and method permit components to be interconnected in a soundproofed manner.</p> |
