Introduction to Operational Modal Analysis
Rune Brincker – Aarhus University, Denmark

Operational Modal Analysis (OMA) is the technology of estimating modal properties of structures from the operating response. Over the last decade this technology has become more widely used as a supplementary tool to traditional experimental modal analysis where a controlled test is performed and both input and response is known.

Introduction to Operational Modal Analysis comprehensively covers the basic principles and practice of OMA. It presents an overall picture of the OMA technology, and covers all important aspects that are needed to understand why OMA is a practical tool for modal testing.

It is organized into four main sections. Part one covers basic concepts and theories needed for a clear understanding of OMA, including probability modelling, matrix theory and regression, transforms theory and measurement technology. Part two offers a review of concepts of classical structural dynamics covering general damping and discrete time solutions, and part three presents concepts associated with random modelling, including random vibration theory and signal processing. Finally part four reviews identification techniques that are commonly used in practical applications, such as the frequency domain decomposition and the poly reference techniques.

Key features:

  • Provides a full theoretical background for OMA
  • Covers advanced topics, including closely spaced modes, mode shape scaling, mode shape expansion and estimation of stress and strain in operational responses
  • Discusses practical applications of OMA
  • Includes examples supported by MATLAB® applications
  • Accompanied by a website hosting a MATLAB® toolbox for OMA

Introduction to Operational Modal Analysis is an ideal textbook for graduate-level courses on modal testing of structures, and is a useful reference for researchers and practitioners working in the field of OMA.
