为解决受限水域对可通航船舶尺度限制的问题,设计一种通过采用特别构造和利用船舶自身配备的装置而在航行过程中改变自身吃水的可变形船舶模型.以这种可变形船模为研究对象,通过分析船舶变形前后的形态特征,探讨其初稳性的变化情况;针对可变形船舶的特点,初步推导附加气囊后的浮心位置计算公式.基于SITC公司的某1万吨级集装箱船的实船参数,以1:180比例缩小的该船的船舶模型的基本参数和试验数据为依据,对该计算公式进行校验.
As the response to dimensional constraints on ships in confined waters, a ship design which can change its draught is proposed by using special construction and equipment on board. The change of the initial stability before and af- ter the deformation is determined through analyzing the morphological characteristics of the ship. A formula for calculating the position of the center of buoyancy is derived. A 1 : 180 test model of a 10 000-ton container ship is built to verify the de- formable design and the calculation formula.
