摘　　要：风电叶片前缘为胶接结构,胶接质量的优劣直接影响到叶片的使用寿命。应用超声脉冲回波法对风电叶片前缘胶接结构进行检测,并通过CIVA仿真分析了探头频率对胶接结构超声检测结果的影响。试验采用设计的超声波双晶探头对风电叶片前缘试块进行了检测。分析结果表明,超声波双晶探头能够接收到明显的胶接区域缺陷回波,可以方便地实现风电叶片前缘胶接结构的检测。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.
