Over 1000 formulas for solving vibration problems in engineering in dynamics acoustics and vibration are presented in 60 tables for quick reference. The formulas allow a specialist or non-specialist equally well to access 200 years of accumulated knowledge and solutions for dynamics, acoustics and vibration. It also lets the reader to calculate the dynamic response of structural, acoustic, and fluids systems and quickly feed back the results into a design or solve the cause of a troublesome noise or vibration problem without resorting to numerical simulations. The presentation of formulas relates design and loads to response in a simple way that numerical solutions lack. Moreover classically based formulas have a new application—to check the results of numerical and computer solutions. The formulas for dynamic analysis are in a table. The text has examples, explanation, and derivations. Chapter 1 provides definitions, symbols, units, and geometric properties. Chapter 2 has dynamics of point masses and rigid bodies. Chapters 3 through 5 provide natural frequencies and mode shapes for elastic beams, plates, shells, and spring-mass systems. Chapter 6 provides fluid and acoustic solutions to the wave equation. Chapter 7 has formulas for the response of elastic structures to sinusoidal, transient, and random loads. Chapter 8 gives properties of structural solids and fluids. Appendices present approximate and numerical methods for natural frequency and time-history analysis. The algebraic formulas are simple enough that a beginner can calculate the results – no calculus is required.
Einzigartiger und bewährter Klassiker zur Qualifizierung von Ingenieuren: die wichtigsten Maßnahmen zur Beruhigung der akustischen Umwelt, Maßnahmen- und Medienkapitel. Aus den Rezensionen zur 6. Auflage: "... Es macht umso mehr Spaß, dieses Buch zu lesen, wenn man ... Akustik wirklich begreifen und ... verstehen will. (Michael Vorländer, in: Acta Acustica united with Acustica, 2005) Die 7., aktualisierte Auflage ist um 200 Seiten erweitert.
Offers practical coverage of vibration stresses and stress-induced displacements, isolation of sensitive components, and evaluation of elastic instability, fatigue and fracture as potential failure modes that arise in mechanical designs and aerospace. The approach taken is particularly useful in the early design stage--the physical problem is defined via known paramaters and a methodology is given for determining the unknown quantities and relating them to specified limiting values and failure modes to obtain an acceptable design. Many of the calculations can be performed on a PC or programmable calculator.
Acoustical engineers, researchers, architects, and designers need a comprehensive, single-volume reference that provides quick and convenient access to important information, answers and questions on a broad spectrum of topics, and helps solve the toughest problems in acoustical design and engineering. The Handbook of Acoustics meets that need. It offers concise coverage of the science and engineering of acoustics and vibration. In more than 100 clearly written chapters, experts from around the world share their knowledge and expertise in topics ranging from basic aerodynamics and jet noise to acoustical signal processing, and from the interaction of fluid motion and sound to infrasound, ultrasonics, and quantum acoustics. Topics covered include: * General linear acoustics * Nonlinear acoustics and cavitation * Aeroacoustics and atmospheric sound * Mechanical vibrations and shock * Statistical methods in acoustics * Architectural acoustics * Physiological acoustics * Underwater sound * Ultrasonics, quantum acoustics, and physical aspects of sound * Noise: its effects and control * Acoustical signal processing * Psychological acoustics * Speech communication * Music and musical acoustics * Acoustical measurements and instrumentation * Transducers The Handbook of Acoustics belongs on the reference shelf of every engineer, architect, research scientist, or designer with a professional interest in the propagation, control, transmission, and effects of sound.
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. Written by several well-known authors, 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.
