EXPLORATION OF WIND TURBINE BLADE LEADING EDG′S BONDING STRUCTUREDETECTING USING ULTRASONIC TECHNIQUE

Abstract

Abstract: The wind turbine blade leading edge is a bonding structure, and the adhesive quality of this structure directly influences the service life of the blade. In this paper, the ultrasonic testing technology is used to detect the leading edge of the blade, and the factors affecting the results of ultrasonic testing are analyzed by CIVA simulation. The designed ultrasonic double crystal probes was used to detect the block of wind turbine blade leading edge. Analysis results show that ultrasonic double crystal probe can obtain obvious flaw echo of bonding region, and can easily detect the deboning defects of the blade leading edge.

Key words: wind turbine blade, ultrasonic testing, simulation, NDT, bonding structure
