Therefore, this paper proposes an enhanced multiple random Fourier features based generalized maximum correntropy criterion (EMRFF-GMCC) algorithm.

Furthermore, the mean square error (MSE) cost function is replaced by the generalized maximum correntropy criterion (GMCC), significantly enhancing robustness against outliers.

Flexible inflatable structures offer advantages such as foldability for storage, ease of inflation and deployment, and lightweight energy efficiency, thereby advancing the engineering applications of artificial structures in underwater acoustic scattering modulation.

A combination of flexible inflatable corner reflectors was utilized to simulate the horizontal directional distribution of echo highlights from complex underwater targets.

To address the non-adaptive decomposition level selection issue in multivariate variational mode decomposition (MVMD), an adaptive MVMD algorithm is developed based on mode energy ratio analysis. This approach dynamically optimizes the decomposition parameter by quantifying energy distribution across intrinsic mode functions (IMFs).

Transverse vibrations occur perpendicular to the panel’s surface and are known for their substantial sound radiation. This study introduces a novel technique for tuning modal radiation efficiency, designed to diminish sound radiation from a sway panel comprised of two vertical and one horizontal segment. Notably, when the primary vibration direction of a panel is parallel to its surface (i.e., sway vibration), both the level of transverse vibrations and the corresponding sound radiation efficiency are significantly reduced. A theoretical model was developed to investigate the interplay between transverse and longitudinal vibrations across adjacent components, shedding light on the sound radiation reduction mechanism. The sway structure exhibited a 43.5 % reduction in maximum transverse displacement compared to a simply supported beam, while the maximum longitudinal displacement was adjusted to align with the transverse displacement levels. Moreover, sway modes, in comparison to simply supported beams, demonstrate reduced radiation efficiency due to their dipole-like sound radiation patterns. Consequently, the maximum sound pressure level of the sway structure was lowered by 7 dB compared to that of the simply supported beam. This model also enables the creation of two sway modes with closely spaced frequencies through precise modifications of lengths and thicknesses, highlighting the significance of asymmetric geometry. Furthermore, comparisons of the proposed model with finite element methods and experimental results confirm a strong concordance, validating the effectiveness of the sway structure in achieving reduced sound radiation.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"238 ","pages":"Article 110796"},"PeriodicalIF":3.4,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
