船舶破舱稳性计算方法分类分析

船舶破舱稳性计算可根据进水类型分为三种计算方法,分别是增加重量法(有自由液面和没有自由液面)两种及损失浮力法。通过改变进水舱长、进水舱距船体中线面距离、进水舱高度、双层底高度等参数,利用增加重量法计算、比较其对船舶破舱稳性的影响,同时比较自由液面对船舶破舱稳性的影响程度,并通过优化船型、船舶主尺度,提升船员应对破舱进水时处理能力等方面提出改善船舶抗沉性的具体措施。

According to the type of water intake,the calculation of ship damage stability can be divided into three calculation methods,increasing weight method(with and without free liquid surface)and loss buoyancy method.By changing the parameters such as the length of the intake tank,the distance between the intake tank and the midline plane of the hull,the height of the intake tank and the height of double bottom,the influence of free liquid on ship damage stability is calculated and compared by increasing weight method.At the same time,the influence degree of free liquid on ship damage stability is compared,and the specific measures to improve ship sinking resistance are put forward by optimizing ship form,ship main scale and improving the crew's handling capacity of dealing with water damage.
