Publisher Summary. This chapter focuses on the vibrational response of structures to incident sound fields. The process of transmission of airborne sound energy through partitions involves vibrational response to sound pressures that acts on one side, and the consequent radiation of. Theory of Sound.

Sound is the mechanical vibrations of particles in a medium. When a sound wave is introduced in a material, the particles in the material vibrate about a fixed point at the same frequency as the sound wave.

The particles do not travel with the wave but react to the energy of the wave.

This book is a collection of papers presented at Acoustics and Vibration of Mechanical Structures – AVMS – Author: Nicolae Herisanu. This chapter reviews a number of different approaches to the active control of mechanical vibration in structures.

The structure is governed by a partial differential equation rather than an ordinary differential equation. In other words, the structure is to be distributed rather than having “lumped” springs, masses and Propagation of mechanical vibration in structures book.

The aim of this book is to address important practical aspects of nonlinear vibration analysis. It presents cases rarely discussed in the existing literature on vibration that are problems of considerable interest for researchers and practical engineers, such as rotor dynamics and torsional vibration of engines.

The book can be used not only as a reference, but also as a graduate-level text 5/5(2). The unique filtering characteristics of periodic structures are demonstrated as functions of their design parameters for structures with geometrical and material discontinuities, and determine the propagation factor by using the spectral finite element analysis and the effectiveness of design on the leg structure by changing the ratio of step length and area interface between the materials is demonstrated in order to find the propagation factor.

RE: Vibration vs. Wave Propagation Analysis. The problem with that approach is that for typical engineering structures the modes of interest are not simple functions of material properties alone. For example the effective speed of sound, that is wavelength*frequency, of a beam in bending.

In this way, the mechanical resonance spectrum of the structure is reflected in a virtually identical spectrum of peaks and valleys in the real part of the E/M impedance measured at the PWAS terminals. An analytical model is constructed using the constrained PWAS analysis performed in.

The vibration response of periodic, beam-like structures has conventionally been studied either by transfer matrix or normal mode methods. The latter method becomes unwieldy if the damping and modal density are high, whereas the former method does not lend itself readily to giving physical silentsoundsparty.com by: The second one is a natural mechanical vibration of the power unit (hydraulic turbine, gear and generator).

It turned out that the structure that supports the generator is not rigid enough. The first one concerns the propagation of pressure waves in the turbine flow system, the frequency of which coincided with the excitation frequency resulting from the electric generator rotational speed.
