| 1 | Impact Localization of CFRP Structure Based on FBG Sensor Network显示文摘Low energy impact can induce invisible damage of carbon fiber reinforced polymer(CFRP).The damage can seriously affect the safety of the CFRP structure.Therefore,damage detection is crucial to the CFRP structure.Impact location information is the premise of damage detection.Hence,impact localization is the primary issue.In this paper,an impact localization system,based on the fiber Bragg grating(FBG)sensor network,is proposed for impact detection and localization.For the completed impact signal,the FBG sensor and narrow-band laser demodulation technology are applied.Wavelet packet decomposition is introduced to extract available frequency band signals and attenuate noise.According to the energy of the available frequency band signal,an impact localization model,based on the extreme learning machine(ELM),is established with the faster training speed and less parameters.The above system is verified on the 500 mm×500 mm×2 mm CFRP plate.The maximum localization error and the minimum localization error are 30.4 mm and 6.7 mm,respectively.The average localization error is 14.7 mm,and training time is 0.7 s.Compared with the other machine learning methods,the localization system,proposed in this paper,has higher accuracy and faster training speed.This paper provides a practical system for impact localization of the CFRP structure. | Yaozhang SAI Xiuxia ZHAO Lili WANG Dianli HOU | 2020 | Photonic Sensors2020，10，1： | 2 |
| 2 | Acoustic Emission Localization Based on FBG Sensing Network and SVR Algorithm显示文摘在实际申请,增强的塑料(CFRP ) 组织的碳纤维是容易的出现各种不可见的损坏。损坏应该因此是及时的为 CFPR 结构的安全定位了并且检测。在这份报纸,一个声学的排放(AE ) 本地化系统为损坏本地化基于察觉到网络和支持向量回归(SVR ) 的纤维布拉格栅栏(FBG ) 被建议。AE 信号,被损坏引起,被高速度 FBG 讯问获得。根据香农小浪变换,在 AE 信号之间的时差基于 SVR 为本地化算法被提取。根据 SVR 模型的意见,没有波浪速度, AE 来源的坐标能精确地被预言。FBG 系统和本地化算法在 500 公里上被验证 ? 獡栠癡? 敢湥漠獢牥敶 ? 硥数楲敭瑮污祬畬襨?襨 吗?? | Yaozhang SAI Xiuxia ZHAO Dianli HOU Mingshun JIANG | 2017 | Photonic Sensors2017，7，1： | 2 |
