Reduction System of Afterbody Vibration due to Surface Force : Mechanism and Effect for Model and Ship

概要

論文の詳細を見る
The mechanism and the effect of a new vibration reduction system are presented. The system reduces surface force with the effect of an air layer in a tank and openings at a hull. On the basis of the pressure measurement in a circulating water tank, a simple calculation model was introduced to estimate the effect of the system on vibration reduction. The calculation model allowed the authors to design the system for a ship. In addition, resistance and self-propulsion tests were conducted in a towing tank, yielding the results that the system hardly gave any influence on propulsion performance. Sea Trials on two car carriers yielded that the system was effective to reduce ship vibration caused by surface force.
