In many scenarios, sensors can be placed directly at the positions of interest. However, in certain situations, it may be impractical or undesirable to deploy sensors at all the desired locations. To address this issue, this paper introduces a novel active vibration control method based on virtual sensing technology. The active control is realized by integrating Macro Fiber Composite (MFC) patches into the main structure to act as the actuators and sensors. The main structure studied in this paper is a joined conical-cylindrical shell. The electromechanical coupling dynamic model of the intelligent structures is formulated based on the eight-node super-parametric shell element and Hamilton’s principle. In order to apply virtual sensing when using piezoelectric material for sensing, the concept of voltage mode is proposed. On the other hand, in order to update the voltage modes obtained by the FEM model, the operational modal analysis (OMA) is introduced, and the local correspondence (LC) principle is applied. The controller is designed by the PID algorithm. As a result, the active vibration control at sensor-less positions on the structure can be realized. The theoretical results are verified by the simulation and experimental works.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"618 ","pages":"Article 119346"},"PeriodicalIF":4.9,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767018","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}

They represent a promising structural type in aerospace applications due to the lightweight advantage. Conventional transducers, such as accelerometers, are difficult to apply to the rods or strings, making it challenging to measure the dynamic behaviours of tensegrity structures. It has hindered model updating studies and the accurate modelling of these structures, which are of great interest from an industrial point of view. Additionally, state-of-the-art model updating methods, which routinely adjust parameters such as geometric dimensions or elastic modulus for engineering structures, may be inadequate to apply to a tensegrity structure, as its structural stiffness depends on both material properties and prestress in rods and strings. To address these challenges, this paper presents a systematic approach towards validated dynamic models for tensegrity structures. First, a parametric finite element (FE) model is established, and sensitivity analyses of nodal positions, elastic modulus and prestress levels on the natural frequencies of the prism are carried out. Numerical simulations show that the prestress level is a critical factor that affects its natural frequencies. Second, full-field vibration testing of the prism is carried out. A single-point excitation is employed to obtain the frequency response functions, from which three natural frequencies and modal damping ratios are identified. Next, full-field mode shapes of the prism are measured by dwelling the excitation at each of the identified natural frequencies and tracking the full-field vibrations using a non-contact motion capture system. Third, a novel model updating method for tensegrity structures is proposed by utilising the test results. The measured full-field mode shapes are paired with those FE predictions using a modified cross-modal assurance criterion (cross-MAC), with special treatment to account for degenerated modes attributed to the symmetry of the structure. Subsequently, the test/analysis discrepancies of the natural frequencies for the paired modes are minimised by adjusting the prestress levels of strings in the FE model. As shown by the results, the updating process effectively reduces the test/analysis discrepancies of the natural frequencies from 29.2 % to 5.3 %. It also estimates the prestress values as 18.54 N and 22.01 N for the horizontal and diagonal strings, respectively. Finally, direct tension measurements of the strings are carried out as a validation tool for the proposed model updating method. Discrepancies in the prestress levels of the strings, ranging from 13.44 % to 27.72 %, confirm the feasibility of the proposed method. The parametric model, experimental data, and model updating codes are openly available to serve as a benchmark for accurate modelling of tensegrity structures.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"618 ","pages":"Article 119350"},"PeriodicalIF":4.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739537","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}

However, when multiple TMDs are used for multimodal control, they may cause modal deviations in the primary structure, thereby reducing their effectiveness in vibration control. Furthermore, traditional mode-by-mode design approach cannot account for the synergistic effects between TMDs, thus leading to suboptimal design outcomes. This study focuses on a two-degree-of-freedom(2DOF) discrete structure and proposes an optimization design method based on the synergistic effects between TMDs. The proposed method is compared with the traditional mode-by-mode approach through numerical examples. Subsequently, a complex modal analysis is conducted to investigate the modal deviation characteristics of the primary structure under optimal design parameters. Finally, seismic time history analysis is conducted to evaluate the vibration mitigation effects of each TMD and their interactions. The results show that the proposed method can achieve better control performance with a lower damping ratio of TMD2 (control Mode 2) compared to the traditional mode-by-mode design approach. The TMD with a large mass ratio does not affect the frequency or mode shape of the 2DOF discrete structure, but it significantly increases its modal damping ratio. Under the optimal design parameters, both TMD1 (control Mode 1) and TMD2 effectively reduce the peak and root mean square (RMS) responses of the primary structure. When both TMD1 and TMD2 control the first two modes of the primary structure, TMD2 does not affect the tuning performance of TMD1 but reduces its operational efficiency. This effect becomes more pronounced as the mass ratio of TMD2 increases.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"618 ","pages":"Article 119348"},"PeriodicalIF":4.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713764","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 nonlinear equation of motion is obtained using the von-Karman’s geometric nonlinearity and the principle of virtual work. The time domain periodic response is obtained using shooting technique coupled with Newmark’s time integration and arc length continuation method. Finally, the acoustic pressure is evaluated using the time domain Rayleigh integral and elementary radiator approach considering plate vibrations in an infinite baffled plane. The significance of the “zig-zag” function on linear frequencies and nonlinear vibration response is shown through numerical studies. A detailed parametric study is carried out to investigate the effect of boundary conditions, lamination scheme, number of layers, aspect ratio, thickness ratio and core-to-face thickness ratio on the nonlinear vibro-acoustic response of sandwich plates. The influence of these parameters on the A-weighted sound pressure level (dBA) has also been investigated. It is seen that these parameters have significant effects on the vibro-acoustic response of the viscoelastic composite laminated/sandwich plates.

In this study, an HQ filter is proposed, consisting in two superposed annular plates of different thickness, embedded in a solid plate of infinite extension. Propagation in the two parallel plates creates destructive interferences, leading to complete vibration isolation between the central and the external zones. The aim of this study is to develop a consistent formulation for determining the zero transmission frequencies resulting from the annular HQ filter. The analysis follows the Kirchhoff–Love assumptions of classical plate theory and involves solving both the zero transmission frequency problem and a forced vibration problem.

The devices achieve this by rotating the direction of polarisation (i.e. the motion vector) of the longitudinal waves to match the (normally orthogonal) polarisation of shear waves. Previously we have demonstrated mode conversion by adjusting the spatial–temporal distribution of the incident wave amplitude, but this approach cannot convert between modes with orthogonal motion vectors.

The devices presented here reorient the direction of motion by coupling the waves into thin waveguides or “elastic wave pipes” such that a single mode is supported. The pipes are curved, and the motion vectors of the guide waves are thus rotated as the wave follows the pipe.
