E-grāmata: Analytical and Experimental Modal Analysis

"Present book is focused on dynamic design of structures and systems, requiring integration of the numerical modelling tools, experimental techniques of system identification and model updating. The topics of structural dynamic modelling using finite element method, principles of vibration control and system identification using modal testing and FE model updating are presented towards the goal of dynamic design. It gives a unified treatment to these domains in the context of dynamic design for better understanding and appreciation of effective and optimum utilization of the potential of individual techniques to achieve dynamically sound designs. Features: Brings all theoretical and experimental elements required for vibration and dynamic design in a unified way in one place. Shows link between different technologies that need to be employed for dynamic design. Focuses on experimental and numerical tools for dynamic design. Discusses elements required for theoretical and experimental modal testing. Understand the need and techniques of FE model correlation and updating and how it can yield more accurate and reliable predictions. This book is aimed at Senior undergraduates/graduates in structural dynamics; Mechanical, Aerospace, Automotive and Civil Engineering, vibration, modal analysis and testing, structural optimization for dynamic design, dynamic finite element analysis, vibration control and signal processing"--

This book covers the fundamentals and basic concepts of analytical and experimental approaches to modal analysis. It is inspired by this consideration and is written to give a complete picture of modal analysis.

This book covers the fundamentals and basic concepts of analytical and experimental approaches to modal analysis. In practice, the analytical approach based on lumped parameter and finite element models is widely used for modal analysis and simulation, and experimental modal analysis is widely used for modal identification and model validation. This book is inspired by this consideration and is written to give a complete picture of modal analysis.

Features:

• Presents a systematic development of the relevant concepts and methods of the analytical and experimental modal analyses.
• Covers phase resonance testing and operational modal analysis.
• Provides the relevant signal processing concepts.
• Includes applications like model validation and updating, force identification and structural modification.
• Contains simulations, examples, and MATLAB^® programs to enhance understanding.

This book is aimed at senior undergraduates/graduates, researchers, and engineers from mechanical, aerospace, automotive, civil, and structural engineering disciplines.
