Acoustic and Flow Induced Vibrations

Industrial Systems

About the course

Acoustic Induced Vibrations (AIV) and Flow Induced Vibrations (FIV) can cause piping systems to vibrate potentially resulting in fatigue failure. These excitation mechanisms are non-linear and strongly influenced by system settings such as valve openings and fluid velocity. Therefore, it can be difficult to predict the presence in new systems or the best remedial action in existing systems.
In this course you will come to understand the physical concepts of both excitation mechanisms in detail and gain knowledge on strategies to overcome associated vibration issues in the field and reduce the risk when designing new systems. Next to relevant theory, high risk systems and codes & standards, a multitude of real-life cases is discussed including methods for trouble shooting AIV and FIV issues.
The course consists of 4 online, self-study modules combined with 2 online live sessions with the instructor. All training content is provided through your EngineeringTrainer account.
After the course you maintain 1-year unlimited access to the course and the discussions forum. This allows you to perform modules again when you need to refresh the knowledge for your projects.
