Torsional−vibration analysis
The forces of gas and inertia from the engine can cause vibration of the entire drive line. In order to
determine the resonance in terms of position and strength and to avoid overstressing, a torsional−vibration
analysis is required.
This can be carried out by MAN for a fee. The requisite data are to be collected during the project phase in
the form of a questionnaire − "Questionnaire on torsional vibration calculation for ship’s drive line".
