Abstract: Embodiments of the present disclosure relate to a method (100) in particular for checking a mechanical stress acting on an inductive component (210). The method (100) comprises sensing (110) one or more measured quantities dependent on the mechanical stress when an electrical excitation signal is applied to the inductive component (210). Further, the method (100) comprises determining (120) the mechanical stress acting on the inductive component (210) based on the one or more sensed measured quantities.

Abstract: A device for reducing vibrations in a hydraulic system may have a separating device which has a side for delimiting a fluid-conducting cavity of the fluid system. The device may also have a vibration-reducing unit, which is designed to mechanically adjust the rigidity of the separating device such that vibrations in the fluid system are reduced.

Abstract: A device and a method for influencing a dynamic property of at least one movably mounted body of two bodies coupled mechanically at least via a variably adjustable stiffness along a first force path. The invention includes a damping element with constant damping properties directly or indirectly coupled in series with the variably adjustable stiffness along the first force path Both bodies are mechanically directly or indirectly coupled via a second force path running parallel to the first force path along which at least one adjustable stiffness is incorporated. The damping property of the damping element and the adjustable stiffnesses are coordinated and configured so that a damping property assigned to the device for mechanical coupling can be varied exclusively by the adjustable stiffnesses.

Abstract: Described is an electroactive elastomer actuator having at least one first band-shaped electroactive elastomer coating and at least one first and one second surface electrode, which are separated by the at least one first electroactive elastomer coating. At least one second electroactive elastomer coating is applied to a surface of the second surface electrode facing away from the electroactive elastomer coating, which forms a band-shaped coating material jointly with the first and second surface electrodes and the first elastomer coating located between the two surface electrodes. The band-shaped coating material is wound around a flat coil form while forming at least two coating material layers. A surface of the first surface electrode facing away from the first elastomer coating makes surface contact with the second electroactive elastomer coating.
