Additionally, a mathematical model is proposed to quantify the detected defects accurately. The proposed method, PSO-VMD, combines variational mode decomposition with a particle swarm optimization algorithm to extract the mode conversion signal of a defect S-wave from a complex laser ultrasonic detection signal. This method effectively enhances the S-wave mode conversion signal’s signal-to-noise ratio (SNR). An experimental system using noncontact laser ultrasonic B-scanning is constructed. The system employs fixed excitation and detection methods. Experimental verification is conducted to accurately detect and identify hole flaws inside steel samples, considering variations in burial depths and diameters. The experimental results show that the proposed techniques for detection and signal processing are capable of accurately identifying and measuring hole defects. The relative positional error, which includes both transverse distance and buried depth, is below 5%, while the relative quantitative error, specifically in terms of diameter, is below 8%.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 7","pages":"709 - 725"},"PeriodicalIF":0.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ingress of atmospheric water during aircraft service may cause minor or major damages of airplane crucial components. The percentage of water/ice filling honeycomb cells is an important factor related to possible cell damage. This study is focused on the analysis of the following inspection parameters: (1) influence of panel orientation (horizontal, vertical and Inclined at 30°, 45° and 60°) on the efficiency of water detection, (2) efficiency and optimization of a heating technique in evaluating water ingress, (3) influence of water/ice phase transformation on detectability of water ingress. The numerical analysis was conducted by using the ThermoCalc-3D software in order to evaluate the detectability of water ingress in the cases where a test panel is placed in different spatial orientations. The samples with water and ice were tested and analysed by using several data processing algorithms available in the ThermoFit software to enhance water detection performance. The signal-to-noise ratio concept was used to compare efficiency of image processing algorithms in the inspection of water ingress in honeycomb panels with varying water content, spatial orientation and water/ice phase transformation.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 7","pages":"813 - 825"},"PeriodicalIF":0.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, a simulation model was established to conduct simulation experiments, which verified the feasibility and effectiveness of the method. Secondly, a filtering algorithm using a combination of successive variational mode decomposition (SVMD) and wavelet noise reduction was proposed to analyze the collected wire rope damage signals deal with. The processed one-dimensional magnetic flux leakage signals are converted into leakage magnetic image signals, which are then used as inputs to a classification network. Finally, the improved ResNet network was used to classify and identify the damage signal. The classification accuracy of the signal collected by the single-layer sensor was 90.90%, and the classification accuracy of the signal collected by the double-layer sensor was 94.05%. The device designed in this study demonstrates a 3.15% improvement in defect classification accuracy, confirming the feasibility and superiority of using difference signals for defect detection.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 7","pages":"801 - 812"},"PeriodicalIF":0.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two configurations of a modified near-field microstrip probe (NFMP) are designed and studied, featuring a tip and a dipole termination. Simulations and experimental tests are conducted to assess the probe performances in detecting microcracks. Notably, the detection of cracks of 10 × 20 × 30 μm is achieved by leveraging the shift in resonance frequency. However, the impedance mismatch between the VNA and the probe presents a challenge to the system sensitivity. To address this limitation, a modification is proposed, introducing a surface-adjustable capacitance to the microstrip. This enhancement improves the probe sensitivity and enables full adjustability during measurements. An improvement of 27.13 dB in the reflection parameter is obtained. The developed probes provide nondestructive testing capabilities across a wide frequency range, from 1 kHz to 1 GHz, making them well-suited for integration with VNA systems and facilitating rapid and reliable external measurements.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 7","pages":"790 - 800"},"PeriodicalIF":0.9,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
