This course will introduce the delegates to Operational Modal Analysis, especially to systems with harmonic components, such as rotating machinery. This will be achieved by combining theory and laboratory exercises. Numerous case studies from the Marine and Energy business will be presented.
Upon completion you will...
have gained insight and knowledge of Operational Modal Analysis applicable for vibration problems of machinery and processes.
