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.

研究了一种新型的高速双体船，采用被动式运动控制系统。为了减小舱室在波浪中的运动，舱室通过铰链和弹簧连接到双体船体上，并配备了全淹没的水翼。主要从数值计算上说明了新船在波浪中减摇的可能性。本文以一艘同类型的双体船为研究对象，将连接铰链改为弹簧，以获得减小垂荡运动和纵摇运动的结果，并将数值计算结果与试验结果进行比较，结果表明，该方法能有效地减小垂荡运动和纵摇运动，并能有效地减小纵摇运动和垂荡运动。用2m长的模型在规则波和不规则波中进行了模型试验。计算结果与试验结果吻合较好，计算方法可用于实船设计阶段的波浪性能预报。
