FEASIBILITY STUDY OF VIBRATION ABSORBERS WITH SIMPLIFIED SHIP PROPULSION MODELS

Abstract Torsional vibrations on the propulsion drive train of a ship due to harmonic loads are thoroughly analyzed by classification societies. During operation however the drive train is subjected to transient loads and the mass- elastic system interacts with the speed controller. Here we derive a smart reduced model of the ship propulsion system capable of revealing the low frequent dynamics which dominate the transient response. A possible approach to counter the damage caused by transient loads, is the attachment of a vibration absorber. The simplified model allows us to check the feasibility of this approach.
