摘要： A wind turbine rotor blade load emulator arrangement includes a support unit constructed to support a rotor blade during a fatigue test procedure; an exciter configured to deflect the rotor blade during a fatigue test procedure; and a stiffness augmentation assembly for mounting to the rotor blade over a mounting length, which stiffness augmentation assembly is realized to increase the stiffness of the rotor blade in the mounting length. A method of carrying out a fatigue test procedure on a wind turbine rotor blade uses such a load emulator arrangement.

摘要： Provided is an exciter device for fatigue testing of a blade of a wind turbine, including a actuator for generating a periodic excitation force and a coupling device for coupling the actuator to a blade to be tested. The exciter device includes a pretensioning device applying a pretension such that the excitation force only acts in a pulling or pushing direction over the whole period.
