Quaternionic attitude algorithm is introduced to characterize the rotational attitude of bearing inner raceway and the balls in three dimensions. Meanwhile, in order to accurately portray the bearing physical variables, the proposed model considers multiple rigid body degrees of freedom, dynamic circular motion, mixed elastic lubrication of the bearings, and dynamic changes in the position and speed of the contact points between the balls and the raceway. The proposed model is validated by experiments. The effect of compound fault on the bearing physical variables (quantities) characteristics is investigated.

This paper presents a cost-effective approach to vibrational analysis using off-the-shelf cameras to capture videos of forcibly excited structures. The method combines forced excitation with phase-based optical flow to extract sub-pixel displacements, eliminating the need for motion magnification. Forced excitation facilitates temporal Fourier analysis, optimising sub-pixel displacement extraction, enhancing sensitivity, and improving efficiency. In contrast to traditional methods that require high-frame rate cameras and extensive computational resources, this system operates effectively with a low-frame rate camera, making it well-suited for NDE applications in industrial settings. Visual vibrometry works on the principle that damage alters a structure’s vibrational response, using changes in pixel values as motion sensors for sub-pixel measurements. Forced excitation amplifies sensitivity by actively probing structures, aiding in early-stage damage detection.

Nonlinear energy sink (NES) refers to a broadband vibration damping technique that was developed based on the targeted energy transfer (TET) of nonlinear systems. The SSVI-NES, which achieves the TET by means of asymmetric single-sided vibro-impacts, can offer improved TET with a faster time scale and enhanced robustness with respect to forcing conditions when compared to other types of NESs that are constructed with smooth nonlinearities. However, the resonance mechanisms and frequency response characteristics of such SSVI-NES, despite special significance in vibration damping analysis, remain an open question due to the difficulties associated with non-smooth terms. In this paper, for the first time, by proposing an alternative frequency–time harmonic balance technique into the Hunt and Crossley vibro-impact model, the forced response curves (FRCs) of such SSVI-NES is calculated, allowing one to uncover the dynamical mechanism of the SSVI-NES and its vibration-damping performance with physical in-depth. Thanks to the FRCs, the resonance mechanisms as well as the bifurcation conditions of the SSVI-NES are then comprehensively investigated with a specific focus paid to the parametric evaluation effects of the forcing amplitude, the stiffness, and the impact loss, revealing the rich response regimes of the SSVI-NES.As a result, a set of easy-to-use design criteria for SSVI-NES is finally obtained to realize vibration suppression over a wider range of forcing amplitudes and frequencies for subsequent generalization to complex structures.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"612 ","pages":"Article 119150"},"PeriodicalIF":4.3,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911967","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, the accuracy of the estimated results depend on the chosen model, for which various complexities exist, making this a challenging task. Two of which are the lack of information required to model the Rotor-Nacelle Assembly (RNA), and the high uncertainty associated with the soil–structure-interaction (SSI). Therefore, the primary focus of this work is to avoid these limitations by considering a suitable substructure which eliminates the need to model the RNA and the SSI, thus significantly reducing uncertainties. The substructure is obtained by ‘cutting’ the OWT at the top of the tower and at the ground level. To define the model, the resulting substructure then only requires geometries and material properties for the monopile and tower; information which is often known with greater certainty. A numerical case study is presented to investigate the accuracy of the proposed approach for input-state estimation of a 15 MW OWT. A series of commonly used setups involving accelerometers and inclinometers are used and the effects on the predicted fatigue life of the structure are discussed. Additionally, a simple approximation of the wave loading is considered to estimate and account for its contribution to the dynamics of the substructure. The proposed approach is shown to be an effective solution for input-state estimation of OWTs when the RNA or SSI are unknown or associated with significant uncertainty.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"612 ","pages":"Article 119153"},"PeriodicalIF":4.3,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143923215","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}
