估算集装箱船横稳心高度的近似方法

The Approximations for Evaluating the Transverse Metacentric Height of Container Ships

横稳性高度KM值是集装箱船总体设计时考虑满足稳性衡准的重要参数。本文利用船宽吃水比B/T、方形系数C_b、水线面系数C_w和KM/T的基本关系,通过实船数据的分析比较,推荐了适用于集装箱船方案设计/初步设计阶段估算KM值的KM/T～B/T、C_b、C_w的近似计算公式和由此得出的图谱。实际应用表明,在集装箱船尺度,系数范围内具有令人满意的精度。所推荐的公式还可用于集装箱船主尺系数优化设计,图谱则可方便、简捷地估算实船的初稳性参数。

In this paper, the approximations, including an expression and a group of diagrams of KM/T-B/T, Cb, Cw, for evaluating the transverse metacentric height of container ships are suggested. In the primary stage of ship design, they are also available for computing the initial stability and determining the form coefficients of container ships.
