  • Publication number: 20220010780
    Abstract: A method for testing a rotor blade of a wind turbine may include predefining a setpoint bending moment distribution. At least two active load-introducing means may be provided which each engage on a load frame. A first of the at least two active load-introducing means may be configured for introducing load in a pivot direction of the rotor blade and a second of the at least two active load-introducing means may be configured for introducing load in an impact direction of the rotor blade. Also provided is at least one passive load-introducing means. A cyclic introduction of load is effected by the at least two active load-introducing means, where a load introduction frequency of the first active load-introducing means and a load introduction frequency of the second active load-introducing means are selected such that the ratio thereof is rational. A testing device for carrying out the method is also provided.

  • Publication number: 20220004686
    Abstract: The invention relates to a method for determining design parameters (41) of a rotor blade (3, 4, 5) of a machine interacting with a fluid, in particular of a wind turbine, in which quality parameters (39) of the rotor blade are determined non-destructively, in particular by way of measurements, in which target parameters of the rotor blade (40) are determined, and in which the determined target parameters are predefined in an optimization process (33), wherein the design parameters are varied in the optimization process in such a way that the target parameters are achieved, taking the determined quality parameters into consideration. In this way, it is possible to determine the parameters of a present rotor blade which can be non-destructively determined, so as to determine the parameters that cannot be determined non-destructively, or that are difficult to determine, by way of a computer model.

  • Publication number: 20210317815
    Abstract: A wind turbine rotor blade extension fitting element, which extension fitting element is designed as a rotor blade rib with a recess and which can be pushed onto the rotor blade tip of a rotor blade to be extended, in such a way that the rotor blade tip protrudes through the recess and contacts the circumferential surface of the recess in an positive-locking manner. The extension fitting element has, on its outer circumference, an outer circumferential surface onto which a shell-like rotor blade extension can be pushed in an positive-locking manner. A core of the extension fitting element has slits and/or boreholes which, for stabilization, are filled with a material that has a higher strength and/or stiffness than the material of the core. In this way, the extension fitting element is strengthened for the transfer of high loads.

  • Publication number: 20200256774
    Abstract: The invention relates to a method for determining elastic properties of a test body (1) by means of tensile or compressive loading in a test stand, wherein a center of gravity line (2) is defined for a longitudinal axis for the test body, said center of gravity line miming through elastic centers of gravity of infinitesimally thick discs which lie orthogonally to the longitudinal axis and into which the test body can be divided. The test body is clamped at two clamping points by means of clamping devices (13, 13?), and a force is introduced at at least one of the two clamping points in the direction of the respective other clamping point such that a line of action of a force introduced at at least one of the clamping points is substantially parallel to a connection line between the two clamping points.

  • Publication number: 20200255121
    Abstract: The invention relates to a test stand comprising a support (19, 25) which is moveably connected to a wall (18, 18?, 18?), a base, a frame (26) of the test stand or another part of the test stand and can be moved on a predetermined path; an actuator (22) which is connected to the support and by means of which the support (19, 25) that can be moved on the predetermined path, two clamping devices (13) respectively comprising a ball joint, wherein one of the two clamping devices (13) is seemed to the support (19, 25) and the other of the two clamping devices (13) is arranged in an axis (10) with the first of the two clamping devices (13), such that a test body (1) is clamped between the two clamping devices (13) on outer surfaces of the test body and can be maintained by the clamping devices (13), and a test force exerted by a test body by moving the support (19, 25) through the first of the two clamping devices (13) acts essentially along the axis (10).
