A test rig for testing blades for a wind turbine includes a fixing structure where a root end of a wind turbine blade can be fixed, a loading mass structure extending from the fixing structure, and an actuation structure which can apply a sinusoidal force to the loading mass structure so that a counterbalanced resonance is established between the loading mass structure and a blade which is fixed in the fixing structure. Due to the counterbalanced resonance, the force from the test rig onto the floor or other building components can be reduced relative to that known from the traditional rigs for blade testing. |
