To address these limitations, this study proposes a novel Nonlinear Filtered Cepstrum (NFC) method, which leverages a dynamic nonlinear filter design to enhance the representation of intricate signal components. Specifically, the proposed method is driven by a spectral distribution that creates denser filters in the vicinity of those critical frequency peaks to achieve superior time-frequency resolution. More importantly, this method is adaptive and does not rely on the experience of an expert, which is a major advantage when dealing with unknown signals and massive data. Through detailed case studies involving simulation signal, chirp signal, ecological signal, and classical music signal, NFC demonstrates superior time-frequency resolution and robustness compared to conventional methods like Continuous Wavelet Transform, Constant-Q Transform, Mel Frequency Cepstrum and Wavelet Packet Energy Cepstrum. The results reveal that NFC excels in capturing key frequency components and minimizing irrelevant spectral information, especially under noisy conditions. While NFC incurs a higher computational burden, its enhanced adaptiveness and precision make it a promising tool for complex signal analysis.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"619 ","pages":"Article 119396"},"PeriodicalIF":4.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887099","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 paper presents a method using the Green's kernel function (GKFM) to establish a linear time-domain mapping between loads under uncertain circumstances and sensor responses. We develop a regularization framework based on interval analysis and convex modelling to characterize these hybrid uncertainties. Existing non-probabilistic load reconstruction methods typically quantify hybrid uncertainties using a single model (pure interval or pure convex), which may overlook the unique characteristics of different uncertainty sources. This could have an adverse effect on the accuracy of load boundary reconstruction and the robustness of regularization parameter selection. In contrast, this method avoids probabilistic distribution assumptions. By effectively integrating interval analysis and convex modelling, it solves the boundary-value problem for load reconstruction under limited data, refining the upper and lower bounds of the reconstructed load. Crucially, this paper proposes a robust multi-objective regularization parameter optimization strategy to dynamically balance stability and accuracy under the combined influence of hybrid uncertainties. Compared with methods that treat uncertainties homogeneously, this integrated approach provides more compact and reliable estimates.

While Bayesian statistics effectively address uncertainties in measurement and system identification; however existing methods face challenges with closely spaced modes. A recently developed expectation–maximization (EM) algorithm has shown promise in most scenarios. However, the Bayesian goal function has multiple local extrema, especially for closely spaced mode shapes, and selecting an appropriate initial guess to obtain accurate and fast identification remains a challenge. To circumvent the limitation, an innovative two-stage Bayesian method is proposed with improved efficiency and robustness for modal parameter identification on structures with closely spaced modes. In doing so, the posterior distribution is established via the Bayesian FFT analysis and then, the most probable modal parameters are searched in two sequential stages. In the first stage, the closely spaced mode shapes are found pertaining to a joint approximate diagonalization problem, which can be quickly solved by the Jacobi rotation algorithm, without the need to specify an initial guess. Subsequently in the second stage, the natural frequencies and damping ratios are simply obtained through Newton iteration. The two-stage method decouples the optimization procedure and therefore, can substantially improve the identification efficiency. Numerical simulations and experimental data are analyzed to validate our method, demonstrating its superior efficiency and accuracy modal identification in the presence of closely spaced modes.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"618 ","pages":"Article 119365"},"PeriodicalIF":4.9,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831575","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 recent years, video data has been widely utilized for structural response evaluation and damage detection due to its ability to extract structural responses from any location, while phase-based methods have proven highly sensitivity to data anomalies.

Modeling and parameter identification of rotating bladed disks are more challenging than their stationary counterparts. This work introduces an enhanced reduced order model (EROM) tailored for rotating bladed disks, particularly under variable-speed conditions. The EROM accounts not only for stiffness mistuning but also for blade-to-blade damping variations. By using finite element solutions of the tuned bladed disk and cantilevered blade at only three rotational speeds, the EROM can accurately predict the free and forced responses across a wide speed range. In addition, the EROM-based damping mistuning identification method (EROM-DMID) is proposed. A key innovation of this approach is that blade-to-blade damping variations can be identified at any speeds using only speed-independent physical mistuning parameters, which can be obtained in advance through modal testing. A detailed numerical case study is provided to validate the proposed EROM and EROM-DMID methods. Compared with full finite element models (FEM), the EROM demonstrates high accuracy in predicting both the free and forced responses of mistuned bladed disks at any rotational speeds. Finally, the EROM-DMID method was validated using FEM-generated modal test and vibration test surrogate data. Results show that the damping identification error remains below 3 % even at speeds as high as 17500 rpm.
