Abstract: A device for subjecting a cantilevered wind turbine blade to transverse force during a fatigue test of the wind turbine blade, the device comprising: a pivot arm having a longitudinal pivot arm axis and being pivotally supported in an arm supporting structure for pivoting about an essentially horizontal pivot axis, a mass member being connected to the pivot arm, and a coupling member providing a connection between the pivot arm and a blade fixture configured to be fixedly connected to the blade, the pivot axis, the mass member and the coupling member being mutually spaced along the longitudinal pivot arm axis. The system comprises the device and an exciter configured for cyclically subjecting the cantilevered blade to a transverse reciprocating movement.
