Synopsis
Vibroacoustic Simulation: An Introduction to Statistical Energy Analysis and Hybrid Methods helps engineers understand how statistical energy analysis (SEA) can be used in conjunction with deterministic finite element methods (FEM) and hybrid FEM/SEA methods to model vibroacoustic simulations that have a range of applications for the automotive, aerospace, and defense industries. Striking a balance between complex theories and practical applications, the book allows readers to master the full frequency range of vibroacoustic simulation. Systematically approaching both FEM and SEA methods, the book explains why both are necessary in acoustic engineering and how both can be used in combination through hybrid methods. A chapter on industrial case studies features projects from companies like Audi and Airbus to illustrate how the methods discussed have been applied in real-world projects such as fuselage simulation, helicopter noise prediction, interior noise prediction for electric vehicles, train profiles, and more. Worked examples are featured throughout the book and accompanying Python codes are provided online, allowing readers to follow along with the examples and practice on their own., VIBROACOUSTIC SIMULATION Learn to master the full range of vibroacoustic simulation using both SEA and hybrid FEM/SEA methods Vibroacoustic simulation is the discipline of modelling and predicting the acoustic waves and vibration of particular objects, systems, or structures. This is done through finite element methods (FEM) or statistical energy analysis (SEA) to cover the full frequency range. In the mid-frequency range, both methods must be combined into a hybrid FEM/SEA approach. By doing so, engineers can model full frequency vibroacoustic simulations in complex technical systems used in aircraft, trains, cars, ships, and satellites. Indeed, hybrid approaches are increasingly used in the automotive, aerospace, and rail industries. Previously covered primarily in scientific journals, Vibroacoustic Simulation provides a practical approach that helps readers master the full frequency range of vibroacoustic simulation. Through a systematic approach, the book illustrates why both FEM and SEA are necessary in acoustic engineering and how both can be used in combination through hybrid methodologies. Striking a crucial balance between complex theories and practical applications, the text provides real-world examples of vibroacoustic simulation, such as fuselage simulation, interior-noise prediction for electric and combustion vehicles, train profiles, and more, to help elucidate the concepts described within. Vibroacoustic Simulation also features: A balance of complex theories with the nuts and bolts of real-world applications Detailed worked examples of junction equations Case studies from companies like Audi and Airbus that illustrate how the methods discussed have been applied in real-world projects A companion website that provides corresponding Python codes for all examples, allowing readers to work through the examples on their own Vibroacoustic Simulation is a useful reference for acoustic and mechanical engineers working in the automotive, aerospace, defense, or rail industries, as well as researchers and graduate students studying acoustics.

- 8***5 (17)- Feedback left by buyer.Past monthVerified purchaseI didn't see a verbal description of this book as "hardcover" or paperback. Cover design and price were similar to both cover styles. I thought I'd left a question for the seller, but I may have done something wrong. The package was too small to match the hardcovers previously received so I returned it unopened. Seller was very efficient, and packaging offered excellent protection. Haven't checked to see if refund was processed.
