Vibroacoustic Simulation

Vibroacoustic simulation models and forecasts the acoustic waves and vibration produced by an object, system, or structure. Engineers rely on finite element methods (FEM) or statistical energy analysis (SEA) to cover the entire frequency spectrum. In the mid-frequency band, the two must be merged into a hybrid FEM/SEA approach, which allows complete-spectrum simulation of intricate systems such as aircraft, trains, cars, ships, and satellites. Hybrid techniques are gaining ground in the automotive, aerospace, and rail sectors.

Until now, this subject has appeared mainly in academic journals. This book presents it as a hands-on guide to mastering simulation across every frequency band. A methodical progression explains why both FEM and SEA are needed in acoustic engineering and how hybrid methodologies combine them. Theory and practice are kept in balance, with real-world cases including fuselage simulation, interior-noise prediction for electric and combustion vehicles, and train profiles, among others.

The book serves as a reference for acoustic and mechanical engineers in the automotive, aerospace, defense, and rail industries, as well as for researchers and graduate students studying acoustics.
