ENGINEERING VIBROACOUSTIC ANALYSIS Methods and Applications Computational vibroacoustic methods are commonly applied in engineering design. Engineers must therefore understand the fundamentals of the available methods and how to apply them. Taking a practical approach, this book describes methods for simulating the structural vibration, interior acoustics, and sound radiation of mechanical and transportation vehicle systems for low, mid, and high frequencies.

ENGINEERING VIBROACOUSTIC ANALYSIS Methods and Applications Computational vibroacoustic methods are commonly applied in engineering design. Engineers must therefore understand the fundamentals of the available methods and how to apply them. Taking a practical approach, this book describes methods for simulating the structural vibration, interior acoustics, and sound radiation of mechanical and transportation vehicle systems for low, mid, and high frequencies. The book describes analytical methods (based primarily on classical modal synthesis), the finite element method (FEM), boundary element method (BEM), statistical energy analysis (SEA), energy finite element analysis (EFEA), hybrid methods (FEM-SEA and transfer path analysis), and wave-based methods. The book also includes procedures for designing noise and vibration control treatments, optimizing structures for reduced vibration and noise, and estimating the uncertainties in analysis results. Each chapter includes theoretical formulations, along with practical applications to actual structural-acoustic systems. Readers will learn how to use vibroacoustic analysis methods in product design and development; how to perform transient, frequency (deterministic and random), and statistical vibroacoustic analyses; and how to choose appropriate structural and acoustic computational methods for their applications. The book can be used as a general reference for practicing engineers or as a text for a technical short course or graduate course.
