Applied Operational Modal Analysis

This course will give the delegates an introduction to Operational Modal Analysis in general, and more specifically to systems with harmonic components, such as rotating machinery.

Overview

This course will give the delegates an introduction to Operational Modal Analysis in general, and more specifically to systems with harmonic components, such as rotating machinery. This will be achieved through a mix of theory and laboratory exercises.

Upon completion you will...

• have gained insight and knowledge of Operational Modal Analysis, which you can use for vibration problems of machinery and processes

Course content

Day 1

• What are the differences and similarities between Operational Modal Analysis and Experimental Modal Analysis?
• Introduction to Frequency Domain Decomposition (FDD) techniques
• Introduction to Stochastic Subspace Identification (SSI) techniques
• How to apply the co-variance driven Stochastic Subspace Identification technique to industrial problems
• Experiments: comparing FDD, SSI and EMA

Day 2

• Influences of harmonic components
• Experimental and Operational Modal Analysis of rotating machinery
• Experiments: influence of harmonic components, rotating machinery
• Special topics: complex and non-linear systems
Topics will be illustrated with numerous case studies.

Who should attend

Rotating equipment engineers, noise & vibration engineers, project managers and anyone who would like to learn about Operational Modal Analysis.
