The recorded signals were subsequently analysed to gain insight into the system’s motion during resonant vibrations. To analyse the motion of the system in more depth, a numerical method was proposed to determine the mode shapes of the individual vibration components involved in parametric resonance. In the studied system, instability ranges were determined and identified, and the effects of amplitude and excitation frequency on the resulting vibrations were investigated. The study revealed diverse dynamic behaviours, including simple parametric resonances with periodic, polyharmonic, planar vibrations, as well as combination resonances involving more complex, non-periodic, spatial motion.

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.

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. Validation is performed using a space capsule numerical case study.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"619 ","pages":"Article 119389"},"PeriodicalIF":4.9,"publicationDate":"2025-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144863347","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 test bench was built to measure the transmission rate of the system for model validation. Experimental results show that the transmission rate is dependent on both frequency and amplitude, where the orifice-type system exhibits a single resonance peak, while the pipe-type system shows two. Under varying excitation amplitudes, the response curves of the orifice-type system intersect at one amplitude-independent point, while the pipe-type intersects at two. Then, closed-form expressions for the resonance peaks and amplitude-independent points are derived, explaining the mechanisms of the nonlinear responses. The effects of damping ratio, stiffness ratio, and natural frequency ratio on the transmission rate are analyzed.

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}

Results revealed that the conventional formula produced errors of up to 300%. Further investigation identified two primary error sources: the inability to account for the film's Young's modulus contribution and the assumption of longitudinally homogeneous coating. To address these issues, we developed a new mathematical model and validated it through extensive experiments. The proposed model predicts film mass and Young's modulus contributions with an error of approximately 1.5%. Conventional formulas predict a consistent frequency decrease with coating. However, our study demonstrates—both mathematically and experimentally—that frequency may increase or remain unchanged depending on the film’s Young’s modulus and coating uniformity.
