Ship vibration excited by its propeller and its main engine is a high-order vibration coupled by vibrations from the main engine, the shaft, the hull and the superstructure, and elucidation of such vibrational phenomena is very important to ship vibration control design. To achieve it, it is necessary to develop a practical simulation type vibration control design technique capable of reflecting characteristics of exciting forces and the vibration transfer flows from the shaft and the main engine to the ship structure, to computational models, with a fast processing capability. To implement such a simulator, The authors developed Simulation System for ship Vibration based on EWS recently marked with its higher speed and performance achievements. This paper presents verification on the accuracy of this Simulation System for Ship Vibration as well as confirmation of its effectiveness and practicability, based on its application to an actual ship.
