Torsional Vibrations in Steam Turbine Shaft Trains
A collection of practical experiences related to torsional vibrations in shaft trains is given. It also presents different kinds of measurement methods and deals with potential measurement & monitoring systems.
Furthermore, an overview on mitigation measures, which are divided in procedures and commercial systems, is given. Finally, a guide for conceptually detecting and solving torsional vibration problems is provided.
