摘要
针对结构损伤问题,采用损伤定位、定量的分阶段识别方法,即利用柔度曲率改变率指标来确定结构损伤的具体位置,然后以频率改变率为输入参数构建神经网络对损伤部位进行程度识别。通过对一个简支梁的仿真计算,表明上述方法能判别损伤位置和程度,且识别精度较高。
In order to identify structural damage, an approach is proposed. First change rare of flexibility curvature is used to locate structural damage. Then damage extent is identified by neural network technique of change rare of frequency. A simply supported beam is simulated. The Method can identify damage location and extent accurately..
