To address the two major challenges in the practical engineering applications of this method, namely extracting vehicle-bridge contact point (CP) responses and eliminating the adverse effects of road roughness, this paper proposed a novel method for obtaining MP based on tire pressure variations of a two-axle test vehicle crossing the bridge. The process began by converting tire pressure variations into the relative displacement of the axle and contact point (RD of A-CP), which was then utilized in the vehicle vibration equations to solve for CP displacement. By subtracting CP displacements from two consecutive runs, the influence of road roughness can be eliminated. Subsequently, the residual response was subjected to variational mode decomposition (VMD) to obtain the modal components. The MP was identified by applying fast Fourier transform (FFT) and Hilbert transform (HT) to the decomposed components. Numerical simulations validated the adverse effects of roughness on MP extraction and demonstrated the effectiveness of the proposed elimination method. The responses from the two-axle vehicle's front and rear tires successfully identified the first three MPs, including frequencies and mode shapes. In field testing using an inspection vehicle, tire pressure variations effectively identified the first-order MP of the bridge.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"606 ","pages":"Article 119020"},"PeriodicalIF":4.3,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549623","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 study introduces a novel baseline-free bridge damage identification method that requires a minimal number of sensors. An analysis method, named POD-CWT transform method, is introduced. This method incorporates proper orthogonal decomposition (POD) and continuous wavelet transform (CWT). It can effectively identify the locations of damage in girder bridges subjected to loads from moving vehicles. The displacement transducers are arranged in an equidistant manner and used to measure the bridge displacement responses under moving loads. POD is employed to obtain a component matrix, wherein each column represents the vibration mode and dynamic information of the bridge. High-resolution mode shapes are obtained by filtering this dynamic information through a low-pass filter. The first mode is processed using CWT to extract the wavelet energy content, which serves as the structural damage indicator. When structural damage is present, the corresponding wavelet energy content profile at the damaged location undergoes an abrupt change. The effectiveness of this approach is verified by numerical simulations and experimental tests. The presented algorithm eliminates the need for non-damage baseline data and significantly reduces the number of required sensors without sacrificing estimation accuracies.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"605 ","pages":"Article 119012"},"PeriodicalIF":4.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519971","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}

These latter are still suffering of low accuracy even if important recent progresses are encouraging for the future. The experimental approach consists of performing measurements in a hydro-acoustic tunnel with a faithful model and scaling the results obtained to the full-scale. Among many details that could generate in-accuracy of the prediction, we focus on the localization of the sources at the model-scale step. We propose to use the modal approach to determine the position of the sources, their magnitudes and phase. Results of computations are then presented.

This research aims at elucidating the NC design in an integrated piezoelectric inductive shunt for simultaneous vibration suppression enhancement and energy harvesting. In particular, the new concept is to leverage the energy harvesting capacity of the piezoelectric circuitry to supply power to a rechargeable battery to drive the NC element, thereby leading to a new design that enhances passive vibration suppression without requesting external power supply. An analytical model that links the NC internal parameters with the system-level responses including vibration suppression enhancement and energy harvesting is presented. The influence of NC internal parameters is analyzed, aiming at improving vibration suppression while maintaining the positive net power which is the difference between the power generated through energy harvesting and the power consumed by the NC element. The design boundaries and uncertainty effects are examined. The analytical results are demonstrated and validated through experiment.

The model represents the transverse motion of the structure and its radiated acoustic pressures as a sum of harmonic components. The transverse displacement of the structure is periodic and modelled using spectral Gaussian basis functions. These basis functions then relate each displacement component to the periodic cells’ degrees of freedom. Expressions for the time-averaged kinetic and potential energy, as well as the external work done by the acoustic pressures, are derived. Subsequently, these energy formulations are used to establish the equation of motion of the system to determine its response to acoustic excitation. To validate the model and demonstrate its usefulness, two numerical examples of periodic plates with embedded rectangular cells, including those with flexible segments (FS) of constant thickness and ABH thickness profiles, are presented. The dispersion curves and sound transmission loss of the periodic plates with FS are calculated using the proposed model and verified by comparing the results with a well-established wave and finite element (WFE) method. The proposed model is further applied to calculate sound transmission through the ABH plate with a complex cross-section profile. The wave modes and vibration patterns induced by acoustic waves acting on the periodic plates are also analysed. It is found that the periodic plate with a thin FS demonstrates sound insulation capabilities comparable to, or even superior to, those of the ABH plate. The periodic plates’ low- and mid-frequency transmission loss is primarily influenced by global modes, whereas local modes predominantly govern the high-frequency performance. The findings from this study provide valuable insights for designing lightweight plates that effectively reduce sound transmission, particularly at and above coincidence frequencies.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"605 ","pages":"Article 118952"},"PeriodicalIF":4.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143444948","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}
