چکیده
In this research, we analyze the acoustic–vibration coupling of liquid-filled cylindrical shells under complex excitations. A calculation model to determine acoustic characteristics and steady-state response a shell coupled an cavity is proposed. The displacement sound pressure are described by Chebyshev–Fourier series in three dimensions. uncertain expansion coefficient determined with Rayleigh–Ritz model. accuracy convergence method compared those finite element method. spring constraint applied simulate arbitrary boundary parameters. impact these parameters on natural frequency analyzed. Finally, system for various excitation

Tunable cylindrical shell as an element in acoustic metamaterial.
Elastic cylindrical shells are fitted with an internal mechanism which is optimized so that, in the quasi-static regime, the combined system exhibits prescribed effective acoustic properties. The mechanism consists of a central mass supported by an axisymmetric distribution of elastic stiffeners. By appropriate selection of the mass and stiffness of the internal mechanism, the shell's effective...
متن کاملAn Introduction to Speech Sciences (Acoustic Analysis of Speech)
Speech sciences deal with the acoustical characteristics of speech by means of sophisticated soft wares as well as hard wares. Although, a speech science is a well known science in the developed countries, especially the western societies, however, it has been remained almost unknown in Iran, though, in recent years a group of scholars have been involved in this branch of science. The applicati...
متن کاملLateral cavity acoustic transducer.
We present a lateral cavity acoustic transducer (LCAT) capable of pumping and mixing fluids within a microfluidic system using an acoustic energy source from an external piezoelectric buzzer. The device is capable of pumping at flow rates of approximately 250 nl min(-1) and real-time mixing in low flow rate (<1 microl min(-1)) devices typical in microfluidic systems.
متن کاملMeasurement of complex acoustic intensity in an acoustic waveguide.
Acoustic intensity is normally treated as a real quantity, but in recent years, many articles have appeared in which intensity is treated as a complex quantity where the real (active) part is related to local mean energy flow and the imaginary (reactive) part to local oscillatory transport of energy. This offers the potential to recover additional information about a sound field and then to rel...
متن کاملShear layer dynamics of a cylindrical cavity for different acoustic resonance modes
This paper investigates the interaction between the shear layer over a circular cavity and the flowexcited acoustic response of the volume to shear layer instability modes. Within the fluid-resonant category of cavity oscillation, most research has been carried out on rectangular geometries and where cylinders are considered, side branch and Helmholtz oscillators are most common. In these studi...
