风电叶片在线检测技术研究进展

Progress in Research of Online Detection Technology for Wind Blade

就风电设备运行过程中风机叶片的在线检测技术进行了讨论。叶片在线检测主要有两大类,分别是以应变、声发射等传感器检测为核心的侵入式检测和以图像检测为代表的非侵入检测,探讨了这两种检测模式中风电叶片损伤检测的实验手段以及损伤特征提取和识别的算法。

This paper discusses on-line detection technology for wind blade in the operation of wind power apparatus.There are mainly two types of onlinedetection mode:one is based on the sensors such as strain or acoustic emission,the other is non attached mode based on image detection.It also details the test method and algorithm for damage identification.
