Simulation of the relationship between geometric design parameters and wave phase is crucial for elastic metasurface design, but it typically demands large-scale parametric sweeps in 3D numerical simulations, leading to high computational costs. To accelerate the computation, this work proposes a general Numerical Mode Matching (NMM) method for elastic/acoustic wave propagation in vertically multilayered heterogeneous structures. The method decomposes a complex 3D problem into a series of 2D inhomogeneous waveguide eigenvalue problems, solved using the spectral element method (SEM), and a 1D layered medium problem solved analytically using a recursive procedure. The formulation ensures the continuity of displacement and traction at layer interfaces, incorporating solid-fluid coupling with linear-slip boundary conditions. The efficiency and accuracy of the proposed NMM method are demonstrated through several numerical examples. Additionally, a 3D metasurface based on a solid-fluid coupled multilayered resonant unit cell is designed using the NMM method, showcasing its capability to enable functionalities such as wave steering and focusing. The results indicate that the proposed method significantly reduces computational costs while maintaining high accuracy, making it a powerful tool for simulating elastic waves in multilayered heterogeneous structures, particularly in metasurface design.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"625 ","pages":"Article 119608"},"PeriodicalIF":4.9,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we propose an updated Transfer Matrix (TM) methodology that resolves two fundamental limitations in existing approaches: (1) modeling inaccuracies caused by discontinuities in non-uniform cables, and (2) the failure of conventional TM methods due to deformation-dependent transfer matrices. To resolve the first limitation, a segmented catenary element method is proposed, integrating the State-Space Approach (SSA) with the catenary element method. This framework enables the discretization of periodic cable systems into uniform segments, each governed analytically by the hyperbolic equilibrium equations derived from catenary theory. For the second limitation, explicit equations relating transfer matrices to dynamic tension are first derived; then an iterative dynamic tension approach is developed to update the deformation-dependent transfer matrices. By employing the Joint Coupling Matrix (JCM) method to construct the global transfer matrix, the closed-form solution for the vibration responses can be derived. The accuracy of the updated TM method is verified through comparisons between frequency response curves obtained from the updated TM method and those from the Finite Element Method (FEM). The updated TM method is then employed to evaluate the performance of the periodic structure-based vibration mitigation strategy in periodic cable systems, revealing the effectiveness of this approach under different combinations of structural periodic parameters and load conditions. The results provide a theoretical foundation and practical guidance for optimizing periodic cable configurations to achieve enhanced vibration mitigation performance in civil engineering applications.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"625 ","pages":"Article 119601"},"PeriodicalIF":4.9,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The central idea behind this approach is to improve the responsiveness and adaptability of the passive energy absorption mechanism by integrating a control law supported by actuator/sensor pairs. This combination enables the system to dynamically adapt itself to varying excitation conditions, thereby significantly improving overall performance. Meanwhile, nonlinear energy sinks (NES) are well known for their frequency robustness. The weak point of a nonlinear energy sink lies in its activation threshold, i.e.: the absorber is inactive at low or high levels of external force applied to the primary structure. Additionally, under a significant shift in the primary structure’s natural frequencies, the absorber becomes ineffective or inactive. Furthermore, the reactivity of passive absorbers may be insufficient depending on the application. For these reasons, a new device for vibration mitigation called the hybrid nonlinear energy sink is introduced. The latter is designed to overcome the limitations of passive linear and nonlinear absorbers and hybrid linear absorbers. It enhances the non-linear passive energy sink by integrating sensor-actuator pairs and a specially designed control law to modify the system dynamics in real time. This ensures that the absorber remains effective even when external conditions change. This paper presents theoretical and experimental demonstrations of this new device, applied to a one-storey building. By introducing control laws within the hybrid nonlinear energy sink, it becomes possible to adjust its parameters, e.g., the nonlinear stiffness, to shift the activation threshold and ensure consistent performance of the absorber in real-time.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"625 ","pages":"Article 119577"},"PeriodicalIF":4.9,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145787937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two configurational models on the LPDM considering blade stiffness mistuning, that is, Style 1 (MITB-HC without BMPSs) and Style 2 (MITB-HC-BMPSs). The BMPSs are introduced to connect adjacent blades, forming coupled groups to enhance inter-blade stiffness coupling. The effects of HC and BMPSs on natural frequencies, modal localization, and resonant responses are analyzed, with solutions validated against existing literature. Results show that mistuning has negligible influence on natural frequencies but significantly induces modal shape and forced response localization, with severity increasing as mistuning strength rises. Notably, the hybrid system of HC and BMPSs demonstrates superior vibration reduction: compared with single measures, it more significantly weakens vibration localization.

An accurate analytical solution for the MSPH serves as the critical foundation for ensuring calibration precision in the vibrating liquid column absolute calibration method (VLCACM). However, the current VLCACM inadequately considers the effects of hydrophones structure, acoustic field inhomogeneity and dynamic liquid column on the MSPH, leading to compromised calibration accuracy. In this scenario, a novel MSPH analytical framework that explicitly considers hydrophone-liquid column coupling effects is presented in this paper. Firstly, an ESA integral model and a spatial averaging correction theory are developed based on the integrating properties of hydrophones to resolve the liquid column acoustic field vertical inhomogeneity. Secondly, leveraging the Jacobi-Anger expansion, a harmonic correction theory for MSPH is formulated to quantify the effect of hydrophones dynamic measurement point caused by the simple harmonic motion of the liquid column on the MSPH, with recursive relationships derived for harmonic amplitude prediction. Finally, the proposed MSPH correction framework was experimentally validated over the frequency range of 10 Hz to 2000 Hz using a dedicated vibration liquid column calibration platform—comprising an electromagnetic standard shaker and an integrated measurement and control system—paired with a 27.5 mm diameter truncated spherical piezoelectric hydrophone exhibiting a sensitivity of approximately -173.7 dB.
