Mitigation of Diesel Generator Vibrations in Nuclear Applications

In order to minimize the risk for vibration problems, it is vital to have an understanding of what type of problems may occur for different parts of the diesel generator and how it may affect the surrounding components.

In this thesis the vibration characteristics of diesel engines, generators and relevant rotating machine elements are described with a practical approach. Detection, Investigation, Analysis and Mitigation, DIAM matrices have been developed for diesel generators. The developed DIAM-matrices make solving emergency diesel generator vibration problems faster and easier and benefit especially users who are less experienced with these problems.
