Sub-micro-Newton thrusters on space satellites are widely used in spaceborne gravitational wave detection, making accurate measurement of micro-thrust-generated thrust essential. Moreover, micro-propulsion systems often exhibit substantial mass, posing challenges for thrust measurement. This research prompted the development of a sub-micro-thrust measurement device based on the inverted pendulum principle, which with-stands 8 kg loads and boasts a large thrust-to-weight ratio exceeding 109. Experimental results demonstrate that adjusting the stiffness of the inverted pendulum can effectively enhance the resolution of the device. Piecewise constant signal (PCS) thrust force was introduced, and the nonlinear total variation denoising (TVD) algorithm method was adopted for signal denoising. It is validated that thrust measurement in the range of 0–261 μN is achieved with a minimum resolution of 24 nN. The device design and stiffness adjustment method proposed in this paper, as well as the data denoising method utilized, greatly enhance the thrust resolution measurement. This approach enables the development of an accurate micro-thrust model for spaceborne gravitational wave detection missions while simultaneously offering a novel solution for sub-micro-newton-level thrust measurement under heavy load conditions. © 1963-2012 IEEE.

Effect of-ray irradiation on performance of LiNbO₃-based piezoelectric vibration sensors

EPL 2021年第6期136卷 67001-67001页

LiNbO3 (LN)-based micro-electro-mechanical systems (MEMS) vibration sensors exhibit giant perspectives in extreme environments, where a great amount of irradiation exists. However, to the best of our knowledge, it is still unknown whether the irradiation affects the performance of LN-based piezoelectric MEMS sensors. Based on this consideration, it is necessary to model the irradiation environment to investigate the effect of high-dosage irradiation on LN-based vibration sensors. Firstly, the theoretical work is done to study the Compton effect on the gamma-ray irradiation with a 60Co source. After irradiation, X-ray diffraction (XRD) characterization is performed to verify the effect of irradiation on the crystalline of LN thin film. Meanwhile, the performances of output voltages on the five MEMS devices under various dosage of irradiation are compared. As a result, a neglected shift of 0.02 degrees is observed from the XRD image only under maximum irradiation dosage of 100 Mrad(Si). Moreover, the output voltages of cantilever beam vibration sensors decrease by 3.1%. Therefore, it is verified that the γ-ray irradiation has very little influence on the LN-based MEMS vibration sensors, which have great attraction on the materials and sensors under high-dose irradiation. © Copyright © 2022 EPLA.

The quest for quantum materials with diverse symmetry-protected topological states has been the focus of recent research interest, primarily due to their fascinating physical properties and the potential technological utility. In this work, we report on the magnetotransport, de Haas-van Alphen (dHvA) oscillations, and the first-principles calculations of the stannide Cu3Sn that is isostructural with the recently reported topological semimetal Ag3Sn. The magnetoresistance was found to vary quasi-linearly in field. Clear dHvA oscillations were observed under a field as low as 1 Tesla at 2 K, with three major oscillation frequencies Fα=8.74 T, Fβ=150.19 T and Fγ=229.66 T and extremely small effective masses. The analysis of dHvA quantum oscillations revealed a possible nonzero Berry phase, suggestive of the nontrivial band topology. The corroborating evidence for the nontrivial electronic topology also comes from the first-principles calculations which yield a nonzero 2 topological index. These results collectively suggest that Cu3Sn, in analogy to its homologue Ag3Sn, may be another intermetallic stannide hosting topological Dirac fermions. Copyright © 2022, The Authors.

Model Predictive control-Assisted Energy Management Strategy for Hybrid Mining Dump Trucks Based on Speed and Slope Prediction

This article proposes an innovative energy management strategy for hybrid multi-source dump trucks operating under real slope conditions in mining areas. Although previous studies have addressed the energy management issues of hybrid vehicles, few studies have taken into account complex environmental factors such as slopes under actual working conditions. The article overcomes this limitation by integrating a radial basis function (RBF) neural network to directly and accurately predict future vehicle demand power, thereby optimizing the DP-MPC strategy and improving energy efficiency. The results indicate that, compared with the traditional MPC strategy, the proposed strategy reduces fuel consumption by 3.34% and engine start-stop events by 76.2%. Additionally, when compared with another strategy that uses historical data to predict future speed and slope, calculates the vehicle’s future power demand, and incorporates it into the DP-MPC algorithm, the proposed strategy achieves comparable fuel consumption while also reducing engine start-stop events by 69.7%. Notably, the average calculation time for each step is 43.85 ms, which is substantially less than the sampling time of 1 s. To further confirm the real-time performance of the strategy, a hardware-in-the-loop (HIL) test is conducted. © 2025 by the authors.

This paper presents a systematic design of man-made brain corals via the methodology of solid isotropic material with penalization. The matter interchange resistance was minimized in the projected surface domain under volume and length constraints from the perspective of topological optimization. The optimized structures are akin to natural corals with intricate shapes, such as Platygyra , Goniastrea and Lobophyllia . In addition, computational fluid dynamics (CFD) simulations show that these human-made corals can provide shelter to protect polyps from ocean currents. To meet the requirements of batch production, an ultraviolet (UV)-curable resin model was first fabricated using the digital light processing (DLP) technique. Then, a silica gel reverse mold was prepared for casting models in cement and calcium carbonate. The mixture ratio was determined based on tests of workability and compressive strength. Ultimately, an acid corrosion test was conducted to verify the matter interchange capability of the optimized morphology. The results show that the brain folds contribute to the circulation of seawater, maintaining the concentration of nutrients and hindering the deposition of harmful substances. This research has established a new and effective methodology focuses on the creation of artificial brain corals, which is important for environmental restoration. © 2022, The Authors.

The current research and future development of the magnetically suspended gimballing flywheel (MSGFW) and high-precision magnetic bearing are expounded. According to the rotor levitation force, MSGFW can be classified as the magnetic resistance force configuration, Lorentz force configuration and hybrid force configuration. Based on the three types of the flywheel configurations above, the development process of MSGFW is discussed. On the basis, the spherical magnetic resistance magnetic bearing and Lorentz magnetic bearing are introduced in detail. Their operating principles are analyzed through using the magnetic circuit maps. The advantages and disadvantages of the magnetic bearings of the same type are compared. Finally, the developing prospect of MSGFW and high-precision magnetic bearing are expected. It points out that the high dynamic response translation spherical magnetic bearing with collocation between detection and control, the standard magnetically suspended momentum sphere and the magnetically suspended control & sensitive sphere will be the primary research directions of MSGFW. © 2019, Editorial Dept. of JA.
