Patent ID: 7770464

Claim:
A device which provides dynamic load testing of a sample, comprising a bearing, to which the sample can be connected, and a counter-bearing to which the sample can be connected by at least one means for actuating so that the at least one means for actuating introduces dynamic mechanical loads into the sample acting along a load path directed between the bearing and the counter-bearing and extending through the sample which subjects the sample to vibrations produced by the at least one means for actuating providing the dynamic load testing of the sample, wherein the at least one means for actuating includes a solid body conversion material system which undergoes deformations in response to application of energy, and wherein the deformations are at least one cause of the mechanical loads occurring within the sample during the dynamic testing thereof, and wherein the at least one means for actuating produces the vibrations for providing the dynamic load testing of the sample, comprises: a) a base connecting element; b) a load connecting element; c) at least one energy conversion system extending between the base connecting element and the load connecting element including a solid body conversion material, with a predominant direction oriented in a direction of the load path; d) at least one prestressing element extending between the base connecting element and the load connecting element, and exerting a mechanical prestress upon the at least one energy conversion system; and e) at least one shear force diverting element extending between the base connecting element and the load connecting element; and wherein: e1) the at least one shear force diverting element is flexible along the load path, is rigid in directions perpendicular to the load path and includes a two-dimensional element disposed perpendicular to the predominant direction; e2) the base connecting element is connected to the two-dimensional element by at least one connecting element; e3) the load connecting element is connected to the two-dimensional element by at least one second connecting element; e4) the first and the second connecting elements are connected to the two-dimensional element at nonoverlapping regions; and e5) the base connecting element is connected to the counter-bearing and the load connecting element is connected to the sample by an interface including a rigid detachable connection.
