Flexible couplings and dampers are

Flexible couplings and dampers are often introduced into
the marine propulsion shafting system to suppress torsional
vibration [20]. The torsional vibration characteristics of such
a system are, however, correspondingly more complex. The
authors have found that the conventional method of using a
single measurement, and then using a model of the shafting
system to predict torsional vibration stress can lead to significant errors. Such a situation is illustrated in this paper.
