Abstract:
The book covers a broad range of topics related to acoustics and vibration problems encountered in various fields of engineering. It presents some analytical, numerical and experimental techniques applicable to analyze linear and non-linear noise and vibration problems. The 58 papers are grouped as follow: Chapter 1: Analytical Approaches to Nonlinear Vibrations; Chapter 2: Damage Assessment of Structures; Chapter 3: Modeling and Simulation Techniques with Applications; Chapter 4: Biomechanics; Chapter 5: Environmental and Occupational Noise and Vibrations; Chapter 6: Structural Vibration, Attenuators and Isolation.Fifty-eight papers from the May 2013 symposium report research results on analytical approaches to nonlinear vibration, damage assessment of structures, simulation techniques, biomechanics, environmental and cupational noise, and isolation of structural vibration. Three papers from University Politehnica of Bucharest propose mathematical methods for determining the eccentricity of a cantilever rotor, calibrating vibration measurement stands, and estimating the damping coefficients of magnetic dampers. Other topics include dynamic analysis of lower limb prosthesis, noise control in an industrial hall, hysteretic damping of elastomeric systems, and vibration in an engine with neo-Hookean suspension.
