摘要: 风电叶片的粘结区域一旦存在缺陷,将会在很大程度上影响叶片的使用寿命,成为后期事故的隐患。而常规的目视法、敲击法等方法难以准确地对缺陷进行检测和定位。本文应用超声波-回波无损探伤技术,对风电叶片梁帽与腹板粘结处玻璃钢(GFRP)进行扫查。分析结果表明,超声波能够穿透对声音衰减强烈的玻璃钢区域,接收到粘结区域的回波信息。因此,该方法应用于风电叶片无损探伤具有一定的可行性。

Abstract: It is difficult to detect and locate the internal defects in bonding area of the wind turbine blade accurately by traditional methods, such as visual inspection and tapping test, while their development will lead to the breakdown of blades and cause a potential failure of wind energy plants. In this paper, a kind of nondestructive detecting technique, called Ultrasound-Echo, is applied to detect and localize the defects in the glass fiber reinforced plastic (GFRP) bonding area between spar-cap and shear web. The result of scanning analysis shows, the thick sound attenuating GFRP laminate could be penetrated by ultrasound and echo information of the bonding area could be obtained. Therefore, the application of this method in non-destructive inspection of wind turbine blades has certain feasibility.

Key words: wind turbine blades, Ultrasound-Echo, defects, missing bond, kissing-bond
