METHOD AND APPARATUS FOR LOCATING A SOURCE OF DAMAGE IN A LARGE COMPOSITE MATERIAL STRUCTURE

摘要

The present invention relates to a method for locating a source of damage in a blade of a wind power generator, capable of tracing the source of damage in a blade used in a wind power generator. More particularly, the present invention relates to a method and apparatus for locating a source of damage in a blade of a wind power generator, which involve detecting defects using an attenuation map prepared on the basis of energy values of elastic waves so as to accurately locate a source of damage in a large composite material structure. The method for locating a source of damage in a blade of a wind power generator according to the present invention enables a source of damage in a large composite material structure made of two or more materials to be accurately located in a different manner than conventional techniques, and fewer AE sensors to be used as compared to conventional techniques.
