| Abstract: | The application of fiber Bragg grating sensor and BP neural network in structural damage recognition has been studied,in which fiber Bragg grating is used as sensing element,four-side simple supporting plank is investigated,BP neural network is utilized as signal processing means.The experiment indicates that fiber Bragg grating sensor with high sensitivity and good stability is a new signal-collection tool in structural damage recognition.By using fiber Bragg grating as sensing element,damage recognition of four-side simple supporting plank can be successfully realized with BP neural network,and the precision of structural damage recognition can also be increased. |
