High-fidelity models such as nonlinear shell/plate or solid finite element models, which analyze large dynamic deformations with many degrees of freedom, are computationally intensive. The modal rotation method (MRM) is a static analysis method that efficiently analyzes large deformations based on modes and stiffness matrices obtained from any linear or linearized model. MRM targets slender structures with small strains and large displacements and considers geometrical nonlinearity rather than material nonlinearity. Dynamic MRM (DMRM), which was developed by extending the MRM to a dynamic analysis method, can efficiently perform nonlinear dynamic analyses using a modal approach. However, the conventional DMRM was formulated under the assumption that the inertial nonlinearity can be neglected. In this study, a novel DMRM that takes inertial nonlinearity into account was proposed. To achieve this, emphasis was placed on the similarities between MRM and rigid multibody systems. In addition, a damping term has been included in the equation of motion in the proposed method. This enables a comparison between the analytical results of the proposed method and the experimental results with damping effects. The proposed method can account for the inertial nonlinearity in a simulation performed and reduce the calculation time by 98% compared to the nonlinear plate finite element method. Moreover, the proposed method with damping showed good agreement with the experimental results for large beam deformations.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"619 ","pages":"Article 119427"},"PeriodicalIF":4.9,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004146","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}

For complex systems, parametric models prove computationally expensive and limited to known uncertainties, reducing their suitability. In contrast, nonparametric models grounded in random matrix (RM) theory - typically employed for non-parameterizable uncertainties - show strong potential for high-dimensional uncertainty problems. However, conventional nonparametric RM models contain practically meaningless entries, introducing deviations from true physical systems. To address this, this paper proposes a filtered nonparametric model that improves upon the direct nonparametric approach. The filtering process, requiring only entry-wise operations, further enhances computational efficiency. The paper establishes nonparametric models to characterize high-dimensional parameter uncertainty in the pipeline system, and provides an efficient unified framework for coupled pipeline-casing system response prediction. 2D and 3D numerical examples based on real aero-engine structures are developed. The results show that the proposed filtered method effectively avoids the error divergence observed in the direct method, achieving closer alignment with full parametric benchmarks.

The coupling of nonlinear deformation and viscoelastic materials will lead to integral-containing nonlinear viscoelastic terms, which have been overlooked in previous studies. Departing from conventional studies, this paper investigated the nonlinear dynamics of a rotating viscoelastic cantilever beam under stochastic excitation. A new nonlinear dynamic equation is established by integrating nonlinear deformation, rotation effect, and viscoelastic constitution in the modeling process, which is transformed into a set of nonlinear stochastic differential equations with integral viscoelastic terms using the assumed mode method. Numerical simulations and stochastic linearization method are used to analyze the multimodal response of the rotating cantilever beam, in which the results showed that the primary mode vibration dominates the dynamic response. Thus, a theoretical method based on stochastic averaging method is proposed to derive the approximate responses of the primary mode. The nonlinear viscoelastic terms resulting from the coupling of nonlinear deformation and viscoelasticity are converted into a combination of the amplitude-dependent modified damping and conservative forces. Analytical responses are obtained by solving the Fokker-Planck-Kolmogorov (FPK) equation. Finally, the impacts of excitation intensity, damping ratio, rotational angular velocity and viscoelastic parameters on the system response are comprehensively analyzed. The high consistency between the theoretical predictions and numerical simulations validates the effectiveness of the proposed analytical method, which facilitates a deeper understanding the dynamic behavior of viscoelastic rotating beams.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"619 ","pages":"Article 119428"},"PeriodicalIF":4.9,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926190","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}

Such a problem is reduced to an equivalent single-degree-of-freedom base-excited system, where the intricate contact interactions involving the oscillating viscoelastic foundation are assessed by introducing a complex dynamic contact stiffness. This model is intrinsically linear and is based on the assumption that variations in the contact area, relative to the contact length in the static equilibrium configuration, may be neglected. Special attention is given to the phenomena of tapping, that is, the contact separation: the latter is clearly related to the amplitude and frequency of the foundation oscillations. An analytical relation, derived within the linear framework, is obtained to predict the incipient tapping front. To establish the application fields of this linear approach, we implement a Boundary Element Method (BEM)-based model that calculates the contact force, iteratively coupling the contact problem with the dynamic equation of the rigid supported mass. The results confirm that the linear model provides accurate predictions for transmissibility and the separation front under low-amplitude oscillations. For higher amplitudes, a specific frequency range emerges, characterized by tapping mode, thereby verifying the model’s capacity to delineate regions of continuous contact and tapping mode.

When equipped with patches of piezoelectric material, these metastructures exhibit an additional capability: they can harvest energy effectively even from frequencies much lower than the fundamental frequency of an individual resonator. This energy harvesting capability is particularly valuable for applications where low-frequency vibrations dominate. To support the design of metastructures for dual purposes, such as energy harvesting and vibration suppression (reducing unwanted oscillations in the structure), we develop a multi-patch isogeometric model of a piezoelectric energy harvester. This model is based on a piezoelectric Kirchhoff–Love plate – a thin, flexible structure with embedded piezoelectric patches – and uses Nitsche’s method to enforce compatibility conditions in terms of displacement, rotations, shear force, and bending moments across the boundaries of different patches. The model is validated against experimental and numerical data from the literature. We then present a novel, parameterised metastructure plate design and conduct a parametric study to explore how resonator geometries affect key performance metrics, including the location and width of the band gap and the position of the first peak in the voltage frequency response function.
