Book description
Hilbert Transform Applications in Mechanical Vibration
addresses recent advances in theory and applications of the Hilbert
transform to vibration engineering, enabling laboratory dynamic tests to
be performed more rapidly and accurately. The author integrates
important pioneering developments in signal processing and mathematical
models with typical properties of mechanical dynamic constructions such
as resonance, nonlinear stiffness and damping. A comprehensive account
of the main applications is provided, covering dynamic testing and the
extraction of the modal parameters of nonlinear vibration systems,
including the initial elastic and damping force characteristics. This
unique merger of technical properties and digital signal processing
allows the instant solution of a variety of engineering problems and the
in-depth exploration of the physics of vibration by analysis,
identification and simulation.
This book will appeal to both
professionals and students working in mechanical, aerospace, and civil
engineering, as well as naval architecture, biomechanics, robotics,
and mechatronics.
Hilbert Transform Applications in Mechanical Vibration employs
modern applications of the Hilbert transform time domain methods including:
- The Hilbert Vibration Decomposition method for adaptive
separation of a multi-component non-stationary vibration signal
into simple quasi-harmonic components; this method is
characterized by high frequency resolution, which provides a
comprehensive account of the case of amplitude and frequency
modulated vibration analysis.
- The FREEVIB and FORCEVIB main applications, covering dynamic
testing and extraction of the modal parameters of nonlinear
vibration systems including the initial elastic and damping force
characteristics under free and forced vibration regimes.
Identification methods contribute to efficient and accurate
testing of vibration systems, avoiding effort-consuming
measurement and analysis.
- Precise identification of nonlinear and asymmetric systems
considering high frequency harmonics on the base of the congruent
envelope and congruent frequency.
