摘要
本文就频率响应方法在结构健康监测系统中的应用进行研究。运用有限元方法计算了圆形通孔与分层两种损伤对复合材料结构动态特性的影响,尝试利用RBF(径向基函数)神经网络对损伤进行识别与定位,并取得不错的结果;对频率响应方法在结构健康监测系统中应用的可行性及其在健康监测系统中的应用进行讨论。
Frequency response method used in Structure Health Monitoring (SHM) system is discussed in this article. The effect of perforation and delaminate damage to the structure's dynamic characteristic was analyzed by FEM. RBF Neural Network was used to classify and locate the damage, and the result is properly well. The feasibility and the role of frequency response method (FRM) in SHM system was indicate, some other notice of this method was discussed too.
