Description
Book SynopsisThis 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.
