Theoretical analysis demonstrates that the AZM unit-cell's orthogonal mechanical decoupling creates a 25-fold modulus contrast between principal axes, permitting low-frequency vibration reduction while preserving structural stiffness. The developed non-locality homogenization method reveals the underlying mechanism: anisotropic regions facilitate wavelength conversion while periodic impedance interfaces enhance Bragg-scattering, collectively opening the bandgap in the low-frequency range. Parametric studies establish clear structure-property relationships, showing bandgap initiation frequencies can be tuned to 11 Hz (P-wave) and 5 Hz (S-wave) while maintaining broadband performance across various configurations. Experimental validation confirms exceptional performance, with three-periods AZM achieving >75 % wave attenuation, featuring remarkable relative bandwidth.

To meet the requirements of aerospace missions, a distributed active surface compensation strategy based on model predictive control and driven by micro-electromechanical actuators is proposed. A multilayer distributed subsystem model is developed based on the explicit Newmark-β method combined with dynamic substructure modeling method, enabling the formulation of subsystem-level dynamics tailored for distributed control. For each subsystem, the Newmark-β method is applied to discretize the prediction model with information interaction, and a distributed model predictive control method is developed using cable length adjustment as the driving strategy. By introducing the parametric variational principle, the actuator saturation constraint is reformulated as a linear complementarity problem, enabling efficient active surface error compensation. Numerical simulations show that the proposed method is adaptable to different shape adjustment scenarios and the ability to maintain the surface accuracy under sub-controller failures, demonstrating both stability and fault-tolerance. Furthermore, a closed-loop active surface compensation experimental verification system is also built based on the 3-meter-diameter mesh reflector prototype, and the shape adjustment experiments show a real-time surface error reduction of over 90%.

However, the intricate interaction between hydrogen and GBs remains inadequately understood, particularly under complex external loading conditions. In this study, we use atomistic simulations and a geometrical algorithm to elucidate the hydrogen segregation energy spectrum at the GBs of polycrystalline nickel under various loading strategies. Three distinct peaks are identified in all spectra, with segregation energy decreasing under increasing tensile loading. Four types of loading—triaxial compression, uniaxial tension, uniaxial straining, and triaxial tension—are applied, with triaxial tension causing the most dramatic spectrum shift. Notably, a linear relationship between hydrogen segregation energy and local volume change is established for the first time. This relationship reveals that hydrogen solution is almost exclusively determined by local volume change, irrespective of the loading conditions. Uniquely in the spectrum of the uniaxial tension case, a fourth peak emerges, signifying a group of super-trapping sites formed through early-stage dislocation-GB interactions. These findings underscore the distinguishable impact of both elastic and plastic deformation on hydrogen distribution in polycrystals. Furthermore, hydrogen diffusion coefficients are derived through mean square displacement analysis, revealing the hydrogen diffusivity in the lattice and GBs under various loading conditions.

Here, we present a kind of deep-subwavelength metasurface (DSMS), which is comprised of a cluster of mass-spring resonators, and achieve enhanced guidance and energy localization of flexural edge waves (FEWs). The local resonance of the resonators provides a strong coupling between resonators and a substrate, which leads to the guidance of flexural waves, that is, guided modes. From the point of view of dynamic stiffness, the guided modes emerge from the weak equivalent stiffness of area near the resonators: stronger coupling weaker equivalent stiffness. On the basis of these, we design two quasi-periodic DSMSs to realize different amplification of FEWs: rainbow reflection and topological interface state. This amplification can be achieved by simply constructing a one-dimensional array on a plate without structuring the entire plate like conventional metamaterials.

This paper proposes a novel optimization-based configuration method to reduce the incompatible interaction wrench in parallel cable-driven exoskeletons. The human-machine interaction wrench in the parallel cable-driven exoskeleton is first modeled, distinguishing between compatible and incompatible components based on the motion characteristics of the human joint. A passive exoskeletal mechanism is introduced to classify the parallel cables into two segments. The wrenches generated by these cable segments are associated exclusively with the compatible and incompatible interaction wrenches, respectively, thereby decoupling these components. Under this configuration, an optimization is performed on unit cable wrenches to reduce the magnitude of the incompatible interaction wrench while preserving the compatible one. Subsequently, the proposed method is specifically applied to a shoulder rehabilitation exoskeleton. The results of simulations and prototype experiments indicate a significant reduction in the magnitude of the incompatible interaction wrench, thus validating the effectiveness of this method in improving human-machine compatibility.</div></div>","PeriodicalId":56287,"journal":{"name":"International Journal of Mechanical Sciences","volume":"306 ","pages":"Article 110819"},"PeriodicalIF":9.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145108090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
