A semianalytical three-dimensional (3D) elasticity solution for the vibration of the orthotropic plate is presented under arbitrary boundary conditions. Three-dimensional (3D) elasticity theory provides the theoretical support for the energy function of orthotropic plates. The orthotropic plates which have the arbitrary boundary condition are realized by the way of arranging three sets of linear springs at the edges. With the aim of eliminating the nonsmooth phenomenon at the edges, the admissible displacement function of an orthotropic plate is expressed with a modified Fourier series solution. Under this framework, a change that occurs on the boundary conditions only needs to modify the boundary parameters of the orthotropic plate, without the need for new derivation, thus greatly saving the modeling time. The convergence and accuracy of the proposed method are better than those of the published literature. Lastly, the new vibration results and parametric research of thick orthotropic plates as well as the geometric parameter are also presented.

“…The second level falls into a plate-cavity system. [26][27][28][29][30][31][32][33][34][35] The system consists of a rigid box and a flexible panel. Thus, without the influence from other panels, it is easier to determine how the panel structure affects the acoustic field inside the box and reversely, how the cavity influences the panel vibration.…”

The increasing demand for acoustic comfort in vehicles has popularized the vibroacoustic analysis using computer-aided engineering (CAE) tools and boosted the development of various noise control measures. Concerning the often-unknown reliability of a CAE tool and the high cost of testing control strategies in a real vehicle, this paper proposes a test bench called Noise-Box, for benchmarking the CAE tools and testing new control measures. The test bench is designed towards a simple plate-cavity system that is easy to model and analyze, so that any vibroacoustic test performed on it can be accurately reproduced by numerical models. Specifically, it is a concrete box with six rigid walls and an opening that can be covered by flexible or soundproofing panels. The complete design is elaborated, including the cavity's shape and dimensions, the panel's installation and the device's overall configuration. Moreover, the acoustic field provided by the test bench is characterized for the typical features that will guide the device's future applications, covering modal property, reverberation time (or sound absorption) and field diffuseness. This work could be informative and instructive not only for the presentation of the novel test bench but also for the utilized methodologies in its design and characterization.

“…For composite materials, Zhang et al. [19,20] used a modified Fourier series method to investigate the vibro-acoustic characteristics of thin or moderately thick laminated rectangular plate-cavity coupling system, wherein two types of boundary conditions, including uniform or non-uniform, are considered. Further extending this coupling system, Shi et al.…”

The present study is concerned with vibro-acoustic behavior analyses of laminated functionally graded carbon nanotube reinforced composite plates based on Reddy’s higher order shear deformation theory. Four types of carbon nanotubes distributions along the plate thickness are considered, which include uniformly distributed and three other functionally graded distributions. Governing differential equations are derived by means of Hamilton’s principle. The sound pressure and radiation efficiency are calculated with Rayleigh integral. A numerical comparison with available results in the literature is carried out to show the validity of the present model. Furthermore, effects of the carbon nanotubes volume fraction, different thermal environments, lamination angle and carbon nanotubes distribution types on the structural and acoustic response of laminated functionally graded carbon nanotube reinforced composite plates are also investigated.
