TEST EQUIPMENT AND TEST METHODS OF WIND POWER GENERATOR BLADE

摘要

PURPOSE: An apparatus and method for testing the blade of a wind power generator are provided to reduce a dynamic load due to wind on the wind power generator. CONSTITUTION: An apparatus for testing the blade of a wind power generator includes a blade specimen (110), a load applying part (120), an angle variation driving part (130), and a sensor part (140). The specimen has an aeroelastic property similar to the aeroelastic property of the actual blade of the wind power generator. The load applying part applies a load on the specimen. The angle variation driving part varies the pitch angle of the specimen on which the load is applied by the load applying part. The sensor part on the surface of the specimen measures the strain of the specimen according to the pitch angle of the specimen.
