This paper investigates and validates experimentally a direct method of impedance eduction in multimodal sound fields with shear flows on the MAINE Flow facility, which was validated only through simulations. Besides the double-liner configuration proposed to enhance the eduction robustness, additional developments are implemented, including a dominant mode selection algorithm to address the complexity introduced by multimodal fields and a 2-line microphone array design to avoid spurious mode effects. Different high-order incident modes (in the direction normal to the liner) are also considered. Finally, the recommended setup, with two types of liner samples, are used to investigate the effects of flow and incident acoustic field on liner impedance. It is also observed that using antisymmetric high-order modes as incident field significantly enhances the robustness of the eduction process.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"626 ","pages":"Article 119635"},"PeriodicalIF":4.9,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927365","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}

This research provides a comprehensive evaluation of the utility of FRF and TF data across frequency bands for damage detection, localization, and actuator placement optimization. Based on FRF sensitivity formulations in both frequency and modal domains, two closed-form expressions for TF sensitivity are derived using a direct algebraic method, with one involving derivatives of physical parameters (i.e., mass, stiffness, and damping) and the other relying on eigen-solution sensitivities. To address the ill-posedness and uncertainty quantification in damage identification, damage detection schemes are established by solving sensitivity-based damage equations within a Bayesian regularization framework, enabling reliable identification of both single and multiple damage scenarios. Numerical studies confirm the accuracy of the formulas of sensitivity analysis and the Bayesian damage detection method. A comparative analysis of the damage sensitivities of FRF and TF data is also conducted with respect to damage location, excitation position, and frequency range.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"626 ","pages":"Article 119629"},"PeriodicalIF":4.9,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927818","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}

Harmonic balance method and time-domain integration are utilized to compute the system responses and evaluate the performances of two types of meta-plates.

Type II extends the Type I design, elucidating the influence of nonlinearity location, linear stiffness and damping. Based on the insights gained, broadband vibration suppression has seen a significant extension into the lower frequency range, along with a notable improvement in vibration suppression effectiveness.

This motivates the current study to employ the planar Reissner-Simo geometrically exact (GE) beam to investigate the paradox.

The dynamic response is computed using nonlinear finite element method for different parameters. The model is validated for a moving point force with the results obtained from the classical string model. For the case of the moving point mass on the stretched GE beam, computations reveal an absence of the trajectory paradox. Also, the dynamic tension in the GE beam causes early appearance of kinks compared to that in the string model, in the response curves.

Mechanical dampers, commonly installed near the lower end of the cable, are widely used for vibration control. However, as cable length increases, these dampers face challenges in meeting design requirements due to the relatively shorter installation distance and the growing number of target vibration modes. To address this issue, this study proposes a novel negative stiffness friction damper (NSFD) for cable vibration control. The NSFD employs a precompressed spring to generate both the negative stiffness effect and the normal force on the friction interface. A lever arm is introduced to amplify both the negative stiffness and the friction force. Furthermore, high-damping rubber elements are integrated as the viscoelastic connection to provide damping during small-amplitude vibrations, when the friction interface does not engage. The linearized negative stiffness coefficient of the NSFD is derived, and its damping performance is evaluated analytically using an energy equivalence approach. A numerical model of the cable-NSFD system is developed, incorporating friction behavior described by the LuGre model, to further investigate its vibration reduction effectiveness. Numerical analysis results demonstrate that the NSFD significantly enhances the damping performance compared to traditional friction dampers and achieves comparable performance to that of an optimal viscous damper with negative stiffness. Moreover, the NSFD offers improved stability due to static friction and delivers nearly frequency-independent control across multiple vibration modes.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"626 ","pages":"Article 119632"},"PeriodicalIF":4.9,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927864","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}

A further restriction is that the system response is taken to satisfy detailed balance, which places no restriction on single-degree-of-freedom systems, but for multi-degree-of-freedom systems special conditions must apply, one sufficient condition being that the linear damping matrix is proportional to the cross-spectral matrix of the excitation. The approach is based on a combination of concepts from the Wiener series and the Fokker-Planck-Kolmogorov equation. In developing the method a number of subsidiary results are obtained, including a number of spectral relationships which represent a generalization and extension of the fluctuation-dissipation relation that is known in the physics literature.

A mechanical model for a system consisting of a vessel, a direct spring operated pressure relief valve, and two outlet pipes is presented. The mathematical representation is a system of Delay Differential Algebraic Equations (DDAE) with two time delays created by traveling wave solutions of the Partial Differential Equations describing the dynamics in the pipes. Thus, the time delays correspond to wave propagation times in the pipes. The model is an extension to the single outlet pipe (single-delay) setup, which is a mathematical limit case of the two-delay problem. In the case of the single outlet pipe, it was shown that the traveling wave propagation in the pipe stabilizes the equilibrium of the corresponding DDAE. In this manuscript, we show that the two-pipe design is also able to stabilize the equilibrium, but importantly, it substantially expands the parameter domains for which stability holds while it improves the transient dynamics. The study requires the treatment of neutral time delay equations in the presence of delay cross-talk between the two time delays. Analytical and numerical techniques are applied in order to produce stability charts and study the robustness.
