Given that the optical fiber is glued to the substrate, a four-layer strain transfer model is developed to analyze the adhesive’s effect on adhesion performance and to correct the curvature sensitivity coefficient matrix.

Therefore, this paper proposes an analytical model for magnetic noise calculation considering the anisotropy and bending stress of the nanocrystalline MSB. First, the magnetic noise computation model of the nanocrystalline MSB considering anisotropy, is established. Then, the bending stresses of the nanocrystalline ribbons with different curvatures are quantitatively modeled. The nanocrystalline loss under different bending stresses is separated by constructing a stress-dependent dynamic Jiles-Atherton (SDDJA) model. The magnetic noise of nanocrystalline MSB is calculated, and results show that the bending stress in the nanocrystalline MSB is positively correlated with hysteresis loss noise. The difference in average magnetic noises (1–100 Hz) of the nanocrystalline MSB between the experiment and calculation is only 4.17 %, which verifies the proposed method. This research can improve the accuracy of magnetic noise analysis and be the design benchmark for magnetic noise suppression.</div></div>","PeriodicalId":18349,"journal":{"name":"Measurement","volume":"242 ","pages":"Article 116295"},"PeriodicalIF":5.2,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although conventional displacement sensors have been widely adopted, they are contact-based methods which lack scalability. Recently, computer vision (CV) has been applied as a noncontact method to measure displacements. However, fast speed of structural vibration (e.g., in shake table tests) can inevitably cause motion blur that imposes challenges in all image-based object/feature detections, especially for normal portable cameras (without high-speed shutters). To address such issue, the study proposed a multi-vision, full-field sensing framework with affordable cameras using a novel global–local detection and deblurring (GLDD) module, which was designed with a generative adversarial network (GAN)-based deblurring model to enhance detection efficiency and accuracy by restoring blemished videos from multiple perspectives. Rauch-Tung-Striebel (RTS) smoother was studied for data fitting using incomplete observations caused due to severe motion-induced blurs. A shake table test was conducted on an aluminum frame with cameras and conventional sensors monitoring the structural vibrations. Fiducial markers were used to track the movement of the key locations on the structure. Results showed that the proposed method is satisfactory to monitor shake table tests when compared to conventional measurements with root-mean-square errors of 0.51–0.95 mm. The proposed deblurring module restored misdetection by 92.1 %, 50.6 %, and 25.2 % for mild-, medium-, and severe-level motion blurs, respectively. Smoother-based data fitting outperformed filter-based one when dealing with highly blemished images. The proposed monitoring system with GLDD and RTS smoother-based data fitting provides a robust measurement solution when dealing with motion blurs.</div></div>","PeriodicalId":18349,"journal":{"name":"Measurement","volume":"242 ","pages":"Article 116292"},"PeriodicalIF":5.2,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142743959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
