Abstract :
This study investigated the static coupling characteristics of a column-type six-component force/moment transducer. An output model of the transducer was developed and validated through finite element method (FEM) simulations. Length-to-diameter ratio (RLD), deflection angles of strain gauge, and multi-component loads were analysed in relation to transducer coupling. Six transducers with different RLDs and strain gauge deflection angles were tested under single and multi-component loads. It was found that the coupling of Fz under Fx or Fy was pronounced when RLD was small. The coupling of Fz under Fx increased from less than 5 % to 34 % when RLD decreased from 3.5 to 2.0. However, couplings of other components under Fz were not sensitive to RLD. The strain gauge deflection angles had the largest effect on the coupling of the Fz component, its coupling increased from 2.5 % to over 17.5% under Mx as the deflection angle increased from 0 degrees to 6 degrees. However, couplings of other components caused by Fz were not sensitive to strain gauge deflection angle. The couplings under multicomponent loads were found to approximate the superposition of those under single-component loads, with deviations within 2 %, indicating good linearity and easy decoupling of the transducer.

Abstract :
A novel measurement system based on Hanning-window-changing density fringes and two-dimensional vision was proposed for monitoring the tank settlement. The artificial Hanning-window-changing density fringes were attached to the surface of the tested storage tank, and the surface fringes were collected in real time by a far-focus imaging camera at a certain distance, and then the images were processed by a specific image processing algorithm to extract the settlement displacement of the storage tank. The image sequences of tank settlement under different conditions were simulated by SOLIDWORKS 3D modeling, motion simulation and image imaging module, and the main measurement performance influencing factors, measurement feasibility and accuracy were simulated and analyzed. The simulated experimental measurement system of tank settlement was constructed, and its measurement performance was analyzed experimentally. The results show that the proposed system can realize real-time monitoring of the tank settlement displacement, and the measurement accuracy can be better than 10 μm at a distance of 7.5 m. © 2024 Editorial office of Journal of Applied Optics.

Abstract :
A bistable composite tape-spring (CTS) structure is stable in both extended and coiled configurations, which can be fully coiled or folded. Its bistable coiling feature has been employed in a Roll-Out Solar Array and successfully deployed in space; its foldable characteristics is analogous to a flexible mechanical hinge, showing great potential to be applied in an aircraft landing gear. Both the structural coiling and folding mechanics are dependent on tape geometry; whilst the correlated scale effect has not been investigated, which significantly constrains its foldable mechanical hinge designs and smart driving analysis in order to further reduce weight and complexity for conventional mechanical hinges. Here, we studied the folding stability mechanics of the CTS structure towards its full tape-length range, where novel stress and shape transitional mechanisms are revealed. This is achieved by investigating the quasi-static folding process of the CTS, where new stable shape features in terms of critical transitional length and stable folded angle are observed and identified through experimental observations, finite element model, as well as theoretical analysis. Theoretical criteria were then determined from the strain energy analysis in comparison to the predefined folded tape shape features. The folding stability mechanisms towards its full tape-length range were proposed in order to facilitate customized flexible hinge design and in-situ smart driving analysis in order to replace conventional mechanical hinges.

Abstract :
As a promising nondestructive testing (NDT) technique with a very adaptive physical modeling of wave transmission process, terahertz technology is used for the detection and characterization of nonpolar materials and the evaluation of layered and/or defective structures. THz-TDS can also be used to perform spectroscopic analysis and detect structural defects in thermal barrier coatings (TBCs) of aero-engines. Although it is generally difficult to measure the structure of the thin oxide layer of the thermal barrier coatings whose thickness is generally lower than 30 g m (the current axial resolution of the THz-TDS cannot exceed 30 g m). We were able to complete the detection of the oxide layer within 1-29 g m through simulation by using the SWT-BP algorithm. In this study, the analysis was performed on real -world samples, the fitting degree of the SWT-BP algorithm reached 0.77, and the minimum prediction error was less than 0.1 g m. The paper also put forward some improvement measures about the experimental results. (c) 2024 Optica Publishing Group

Abstract :
In response to the need for multiple complete bearing degradation datasets in traditional deep learning networks to predict the impact on individual bearings, a novel deep learning-based rolling bearing remaining life prediction method is proposed in the absence of fully degraded bearng data. This method involves processing the raw vibration data through Channel-wise Attention Encoder (CAE) from the Encoder-Channel Attention (ECA), extracting features related to mutual correlation and relevance, selecting the desired characteristics, and incorporating the selected features into the constructed Autoformer-based time prediction model to forecast the degradation trend of bearings' remaining time. The feature extraction method proposed in this approach outperforms CAE and multilayer perceptual-Attention Encoder in terms of feature extraction capabilities, resulting in reductions of 0.0059 and 0.0402 in mean square error, respectively. Additionally, the indirect prediction approach for the degradation trend of the target bearing demonstrates higher accuracy compared to Informer and Transformer models, with mean square error reductions of 0.3352 and 0.1174, respectively. This suggests that the combined deep learning model proposed in this paper for predicting rolling bearing life may be a more effective life prediction method deserving further research and application.

Abstract :
Multiple modes resonance provides the possibility of broadband filtering and has great potential applications in terahertz devices, including miniaturized spectrometers, hyperspectral imagers and optical switches in communication systems. However, it is difficult to further expand the bandwidth range due to the inability to stack an infinite number of resonant structures in a finite space. Here, an innovative method is reported for manipulating two localized surface plasmon polaritons (LSPP) modes by multiscale-coupled plasmonic fields to realize broadband filtering at terahertz (THz) frequencies. The interaction between two LSPP modes was verified theoretically and experimentally, exhibiting a prominent Rabi splitting and two peaks with high transmittance. Particularly, broadband filtering is accomplished by utilizing a double-layer structure that can be regarded as a cavity for inducing far-field interference. Experimental result demonstrates that the maximum transmission range of the bilayer metamaterial reaches 0.63 THz. Besides, the two wide bands can be integrated into one broadband through near-field coupling effects. The integration of strong coupling and far-field interference expands the transmission range of the double-layer metamaterial, further enhancing its capability for broadband filtering. This unique approach for manipulating multi-mode plasmonic coupling forges a convenient route for realizing broadband filtering.

Abstract :
While thermal barrier coatings (TBCs) are being sprayed onto aero-engine turbine blades, or while the engine blade is working, high temperatures and strong impact forces will damage TBCs under thermal cycles, resulting in the coating peeling off from the blades. The current method of using ECT, IRT, or another method alone cannot achieve the real-time detection of coating defects with both high precision and high penetration power. Two detection methods, namely, terahertz pulsed imaging (TPI) and optical coherence tomography (OCT), were combined to evaluate typical defects observed in TBCs (including internal debonding cracks, surface high-temperature cracks, and surface etched cracks). The results showed that the OCT system successfully obtained the micron-level axial resolution, but the detection depth of the OCT system was limited. The TPI system achieved a higher penetration depth than OCT-hence, it can be used for the nondestructive detection and evaluation of the internal debonding defects in the sample-but its resolution needs to be improved. Following this conclusion, a method is proposed using TPI and OCT concurrently for the nondestructive testing and quantitative evaluation of TBCs on etched cracks, thus achieving progress both in terms of depth and resolution. In our experiment, defects with a depth of 519 mu m and a width of 100 mu m were measured. The proposed method is suitable for situations where multiple defects in TBC samples of blades need to be detected simultaneously during the working process. When there are defects deep inside the sample, more small cracks on the surface can be evaluated to achieve a combination of depth and accuracy.

Abstract :
The outstanding performance of current machine-learning fault diagnosis methods is mainly attributed to the availability of a large amount of labeled training data. However, in practical dynamic weighing systems, the high costs and variability of operating conditions limit the availability of reliable training data, hampering engineering fault diagnoses in dynamic weighing systems. To address this issue, this study proposes a novel cross-sensor fault diagnosis method based on multi-feature fusion using a transfer component analysis (TCA)-weighted k-nearest-neighbor (WKNN) network. Using this method, time- and frequency-domain features are extracted from a laboratory-simulated set of fault data with small batches of real operational data. Source and target domain features are fused, and TCA is applied to map the source and target domain samples to a latent space using kernel functions to reduce the distribution differences among the samples. Finally, the WKNN is employed as a metric learner to enhance small-sample data matching and classification to improve diagnostic accuracy. The results show that with three samples per support set, the proposed method achieves a diagnostic accuracy of 93.33%. Compared with other approaches, the proposed method exhibits stronger generalizability for diagnostic knowledge transference from sensor to dynamic weighing failure data, effectively improving precision in on-site small-sample environments and reducing sample imbalances.

Abstract :
A nonlinear chirp is always introduced to an interference fringe in the Fourier domain optical coherence tomography (FD-OCT), which can be regarded as an amplitude-modulated and frequency-modulated nonstationary signal. It is mainly caused by the non-uniform wavenumber sampling and the dispersion mismatch between the sample and the reference arms. It results in the broadening of the axial point spread function and the degradation of the axial resolution. In this paper, the parameterized instantaneous frequency estimation method (PIFEM) is applied to estimate the phase function of the chirped interference fringe to achieve the linear resampling of the wavenumber space and the rebalance of the dispersion mismatch. The proposed method is efficient and convenient that requires only two interference fringes corresponding to a mirror at different depths in the sample arm of the FD-OCT system. In addition, it is proved that the PIFEM is adapted to compensate for the depthindependent dispersion mismatch caused by the sample comprised of layered structures. The experiment results validate the performance of the proposed method.
