摘要： An apparatus is described for producing a frictional and/or form-fitting connection between two components which are arranged such that they can be moved linearly or rotated relative to one another, for the purpose of transmitting forces and/or force moments which act in a linear and/or rotational manner between the two components, of which the first component surrounds the second component at least in sections with at least one inner wall which faces the second component, and the second component provides at least one active-face element which 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 enters the frictional and/or form-fitting connection with the inner wall. The invention is distinguished by the fact that at least one mechanical stressing element is provided which deploys a restoring force on the active-face element, which restoring force holds the active-face element in the first position, and by the fact that a kinematic system is provided which acts on the active-face element counter to the restoring force, is driven exclusively by a converter material and transfers the active-face element into the second position.

摘要： Interfaces for damping mechanical vibrations are, for example, used for damping vibrations in the automotive or aerospace industry. Said interfaces comprise a base connection element (10), a load connection element (28) and a support element (14), whereby the support element (14) is connected to the base connection element (10) by means of a pre-tensioning device (12). A first energy converter system (16, 18) extends between contact points (20, 22) on the base connection element (10) and contact points (24, 26) on the load connection element (28). A second energy converter system (30, 32) extends between contact points (34, 36) on the support element (14) and contact points (38, 40) on the load connection element (28).

摘要： The invention relates to a device and a method for influencing a dynamic property of at least one movably mounted body of two bodies mechanically coupled at least via a variably adjustable stiffness along a first force path. The invention is characterized in that a damping element (7') with constant damping properties is directly or indirectly coupled in series to the variably adjustable stiffness (9') along the first force path (K1), both bodies (1, 2) are directly or indirectly mechanically coupled via a second force path (K2) running parallel to the first force path (K1), along which at least one adjustable stiffness (9") is incorporated, and in that the damping property of damping element (7') and the adjustable stiffnesses (9', 9") are designed and coordinated with one another in such a way that a damping property assigned to the device for mechanical coupling can be varied exclusively by the adjustable stiffnesses (9', 9").

摘要： A description is given of an electroactive elastomer converter comprising at least one electroactive elastomer layer (3) having a top side and underside, and also an electrically conductive electrode body (1') areally connected to the top side at least in regions and an electrically conductive electrode body (1') areally connected to the underside at least in regions, wherein at least one electrode body (1') has in each case an electrode surface which faces the elastomer layer (3) and in which is present at least one cutout (2) to which can be assigned an area region in which there is no areal bond between the elastomer layer (3) and the electrode body (1'). The invention is distinguished by the fact that a compressible medium is provided in the region of the cutout.
