| Research Abstract |
A new type high-speed catamaran with a passive type motion control system has been studied. In order to obtain the reduced motions of cabin in waves, the cabin was connected to the twin hulls by hinges and springs and it was also equipped with the fully submerged hydrofoil. They showed the possibility of the reduced motions in waves for a new ship mainly from the numerical calculations. However, the capability of the numerical calculations had not been clear since a small number of experiments using a small model.
This research is concerned with the similar type catamaran, in which the connecting hinges are replaced by springs to obtain the reduced heave motions as well as pitch motions.
In order to compare the numerical results with the experimental ones, model experiments have been carried out by use of a 2m long model both in reqular and irregular waves. Fairly good agreement between the calculated and experimental results are obtained and the calculation method can be spplied to the prediction of the performance of the ship in waves in the design stage for a prototype ship.
