Chapter 1Transmission of Sound Through Finite Multiple-Panel Partition

Lu, Tianjian; Xin, Fengxian

Pages: 1 –86

[This chapter is organized as three parts: in the first part, the vibroacoustic performance of a rectangular double-panel partition with enclosed air cavity and simply mounted on an infinite acoustic rigid baffle is investigated analytically. The sound velocity potential method rather than the...

Chapter 2Vibroacoustics of Uniform Structures in Mean Flow

Lu, Tianjian; Xin, Fengxian

Pages: 87 –157

[This chapter is organized as three parts: in the first part, an analytic approach is formulated to account for the effects of mean flow on sound transmission across a simply supported rectangular aeroelastic panel. The application of the convected wave equation and the displacement continuity...

Chapter 3Vibroacoustics of Stiffened Structures in Mean Flow

Lu, Tianjian; Xin, Fengxian

Pages: 159 –205

[This chapter is organized as two parts: in the first part, a theoretical modeling approach is proposed for noise radiated from aeroelastic skin plates of aircraft fuselage stiffened by orthogonally distributed rib-stiffeners and subjected to external jet noise in the presence of convected mean...

Chapter 4Sound Transmission Across Sandwich Structures with Corrugated Cores

Lu, Tianjian; Xin, Fengxian

Pages: 207 –223

[An analytic study of sound transmission through all-metallic, two-dimensional, periodic sandwich structures having corrugated core is presented. The space-harmonic method is employed, and an equivalent structure containing one translational spring and one rotational spring per unit cell is...

Chapter 5Sound Radiation, Transmission of Orthogonally Rib-Stiffened Sandwich Structures

Lu, Tianjian; Xin, Fengxian

Pages: 225 –288

[This chapter is organized as two parts: in the first part, wave propagation in an infinite sandwich structure with two periodic sets of orthogonal rib-stiffener core is theoretically formulated when subjected to a harmonic point force excitation. The motions of the equally spaced rib-stiffeners...

Chapter 6Sound Propagation in Rib-Stiffened Sandwich Structures with Cavity Absorption

Lu, Tianjian; Xin, Fengxian

Pages: 289 –339

[This chapter is organized as two parts: in the first part, a comprehensive theoretical model is developed for the radiation of sound from an infinite orthogonally rib-stiffened sandwich structure filled with fibrous sound absorptive material in the partitioned cavity, when excited by a...
