摘要:
An apparatus is disclosed for producing a frictional and/or form-fitting connection between first and second components which are linearly or rotationally movable relative to one another for transmitting forces and/or force moments that act between the first and second components in a linear and/or rotational manner. The first component surrounds the second component at least sectionally with at least one inner wall that faces the second component, and wherein the second component features at least one active-face element that can be transferred in a force-loaded manner from a first position, in which the active-face element is spaced apart from the inner wall, into a second position, in which the active-face element produces the frictional and/or form-fitting connection with the inner wall. The invention includes at least one mechanical stressing element for exerting a restoring force upon the active-face element which holds the active-face element in a first position, and a kinematic system acts upon the active-face element opposite to the restoring force and is driven exclusively by a converter material, with the kinematic system transferring the active-face element into the second position.

Interfaces for damping mechanical vibrations are used, for example, for damping vibrations in the automotive or aerospace industry. The interfaces have a base connection element (10), a load connection element (28) and a support element (14), with the support element (14) being connected to the base connection element (10) via a pretensioning device (12). A first energy converter system (16, 18) extends between engagement points (20, 22) on the base connection element (10) and engagement points (24, 26) on the load connection element (28). A second energy converter system (30, 32) extends between engagement points (34, 36) on the support element (14) and engagement points (38, 40) on the load connection element (28).

摘要:
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.

摘要:
A device is described for vibration damping, which is attachable on a mechanical structure or integratable therein, having at least one mass which is indirectly or directly operationally linked to the structure via elastic means, referred to as the so-called damper mass, and at least one actuator for changing a stiffness which can be associated with the elastic means.
