In a noisy environment, the sound field of source is composed three parts, which are: The that would be radiated by target into free space, incoming from disturbing sources or reflections, and scattered created wave falling on source. To accurately identify with nearfield acoustic holography in situation, last two parts must removed mixed field. previous study, method for recovering environment was proposed based equivalent measurements pressure [J. Acoust. Soc. Am. 131(2), 1260–1270...
To overcome the contradiction between resolution and measurement cost, various algorithms for reconstructing sound field with sparse have been developed. However, limited attention is paid to computation efficiency. In this study, a fast reconstruction method proposed based on Bayesian compressive sensing. First, problem modeled by decomposition of via singular value decomposition. Then, sensing adapted reconstruct pressure. Numerical results demonstrate that applicable either spatially...
Two sound field separation techniques based on equivalent source method are proposed:one is the double-layer pressure measurements and other single-layer pressure-velocity measurements. In this paper, a technique but using velocity proposed. First, theoretical description of given, then numerical simulations experiments conducted to demonstrate validity technique. By comparison with measurements, superiority proposed in separating particle shown. And also, simulations, influences strength...
Abstract Traction motor bearings are crucial for guaranteeing the safe operation of metro vehicles. However, in traction bearing fault diagnosis, there usually problems small samples and missing samples, leading to inaccurate results. Therefore, a novel diagnosis method utilizing track-vehicle-bearing coupled dynamic model improved deep convolutional generative adversarial network-multiscale neural network with mixed attention (IDCG-MAMCNN) is proposed this paper. The IDCG-MAMCNN combines an...
Safety gear is one of the most important devices elevators for its core function to brake over-speed cabin with friction. The frictional braking elevator safety a fully coupled thermo-mechanical process, and therefore both thermal performance mechanical properties during should be comprehended tribological design high-speed gear. In this work, model developed investigate behaviors emergency progressive proposed model, sliding treated as interfacial failure contact surface, transient analysis...

Abstract Metallic materials usually contain some amounts of inclusions which are known to affect their mechanical properties since the bonding strength matrix–inclusion interface is relatively low, voids or cracks thus easily formed under a tensile loading. However, contact loading, effects subsurface on sliding wear metallic not thoroughly understood. In this work, micromechanical model proposed study shear fracture and containing random inclusions. With model, crack branching aggregation...
The traditional near-field acoustic holography technology (NAH) needs to adapt the Nyquist sampling theorem, which requires numerous points be arranged on plane obtain accurate sound source reconstruction results. Non-synchronous Measurements (NSM) was proposed enhance accuracy of and reduce measurement cost. However, investigated object conventional NSM are only sparsely distributed sources, limited attention is paid reconstructed spatially extended source. In this article, further in...
Sparse regularization has been successfully applied to equivalent source method (ESM) in order improve the acoustic imaging resolution. However, application is not always feasible, especially at low frequencies. To overcome problem, this paper proposes a high-resolution method. In method, reweighted l 1 minimization introduced ESM deal with ill-posed inverse problems. Then obtained strengths are used locate sound sources. Compared sparse regularization-based ESM, proposed can provide side...
