基于支持向量机的航空复合材料敲击检测研究

Study on Percussion Detection of Aerospace Composite Materials Based on Support Vector Machine

复合材料在生产和制造过程中难免会存在缺陷和损伤,严重影响航空安全。敲击检测是目前运用最广泛、最简单的无损检测方法。通过对敲击检测的原理研究,对敲击的方式进行了优化,在此基础上运用支持向量机对敲击的数据进行处理。实例验证结果表明,基于RBF的支持向量机的敲击检测方法可以实现对航空复合材料缺陷的有效检测。

Defects and damages are inevitable in the process of manufacturing of composite materials,which seriously affects aviation safety. Percussion detection is the most widely used and the most simple nondestructive testing method. Based on the principle of percussion detection,the method of percussion is optimized. On this basis,the support vector machine is used to deal with the data. The experimental results show that the SVM detection method based on BRF can effectively detect the defects of aviation composite materials.
