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 ：
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 ：
Space deployable structures are able to be deployed from a folded state to a predetermined or desired configuration. They are superior in terms of spatial packaging ratio, controllability, and structural complexity, in order to solve the space limitations for aerospace vehicles. Therefore, they have been applied in structural designs and concepts for various aerospace missions, including space support booms, space deployable antennas, solar panels, as well as flexible solar sails. Recent development of advanced manufacturing technologies and applications of novel smart materials and structures, brings new degree of design freedom to space deployable mechanics, inspiring novel space deployable mechanisms, especially for smart driving and control strategies. Here, we present a review on development of mechanics and smart driving of space deployable structures. Advantages and limitations for various deployable mechanisms are also presented to reveal further insights. The trends and future deployable mechanics are directed by further advancements in terms of modularisation, intelligences, and deployment precision. Multi-disciplinary cross-integrations are leading the way for future breakthroughs in novel deployable mechanics and intelligent driving control for space explorations.

Abstract ：
In response to the high-precision and multi-dimensional force measurement requirements in the fields of biology and medicine, this paper proposes a novel three-dimensional microforce measurement method based on the broadband optical coherence. A novel, compact, and low-coupling elastic element was designed, with a maximum outer diameter of 26 mm and a capacity of 50 g in the X-, Y-, and Z-directions, respectively. The functional relationship between the displacements of the three detecting points on the elastic element and the applied external force was derived based on the elastic mechanics theory. And it was also verified by the finite element method. A self-built optics system was set up to sense the displacements of the three points on the elastic element. The experiments results showed that the resolution in the X-, Y-, and Z-directions was 0.10 mN, 0.11 mN and 0.13 mN, respectively. In the measuring range of (10-50) g, the maximum coupling rate was 4.55 %, and the maximum linear error was 4.70 %. The maximum repeatability error was only 0.615 %. The method and sensor were verified with good characteristics of high resolution, low coupling rate, high linearity and high accuracy, comparing to other reported researches. The multi-dimensional force measuring method could be used in the fields of biology and medicine.

Abstract ：
A novel weight sensor based on the Michelson interferometer is proposed in this study to meet the demands of complex environments. The sensor uses a dual-beam type elastic element, optimized to enhance its sensitivity. Its deformation under load is sensed by a broadband optical coherence displacement measurement system, which, in combination with the spectrum correction method, enables displacement sensing down to sub-nanometer res-olution. An optical interferometric weight sensor with a rated load of 6 kg is fabricated under laboratory con-ditions, and its performance is verified experimentally. The proposed weight sensor demonstrates good stability and achieves a sensitivity of 146.814 mu m/kg, theoretical resolution of 0.004 g, nonlinearity error of 0.034%, maximum repeatability error of 0.036%, and maximum hysteresis error of 0.055%, with the relative error of the identification threshold not exceeding 0.1%. The proposed weighing method and sensor represent a significant improvement over other reported interferometer-type weight sensors.

Abstract ：
Nanoscale polymeric coatings have been developed and utilized in a wide range of industries for decades. The ability for quality control at nanoscale is critical to large-scale industrial development. Nondestructive testing (NDT) techniques play vital roles in structural health monitoring of the nanocoatings throughout their lifetime stages. In terms of recent advances in quality control of nanocomposite coatings, here we present and discuss the commonly used inspection techniques for ex-situ detections, as well as the promising in-situ or inline monitoring methods, with a focus on the application of NDT techniques. Future development of NDT techniques for polymeric nanocomposite coatings will be directed toward intelligent and automated inspection systems, in order to avoid errors caused by human factors and further improve accuracy and reliability. © 2023 Elsevier Inc.
