    摘要: A vibration absorber which, in the broadest sense, is based on a pendulum device for dampening undesirable vibrations which occur in a very slender structure, such as a wind turbine. The undesirable vibrations are caused by an acting force, in particular wind force. The invention thereby relates to vibration absorbers in which the pendulum mass can be temporarily stopped or braked, either entirely or partially, by an electromagnetic brake. The power supply or the current regulation of the electromagnetic brake correspondingly controls the braking function of the electromagnetic brake.

    摘要: Elastomer components, which are to have an elastomer volume with a sufficiently large prestress, as is required, for example, for use in wind energy plants. The elastomer components are substantially based on the incorporation and integration of separating elements into the elastomer body of the component, the elements are disposed either individually or in structures. The body may be compressed by pressure supplied into the region, between the separating elements and the surrounding elastomer material, or directly into the separating elements, such that the elastomer components are prestressed in a dynamically adjustable manner.
