船舶在纵倾状态下稳性的粗略计算法

对初稳性高度GM的通常求法是先根据本船平均吃水,以此查静水力曲线图,再据一系列公式求得,在船舶吃水差不大的情况下,此方法计算出的GM与实际GM接近,当船舶吃水差很大,计算GM可能与实际GM有较大出入,这对船舶的安全可能是不利的。文章从求稳性最原始方法入手,采用较粗略的方法提出了船舶在较大的纵倾状态下船舶初稳性高度计算和相关曲线图绘制的方法。

A Method of Roughly Calculating Ship''''s GM on an Uneven Keel at Trimming State

The way, according to the mean draft got from the ship's six sides' draft and Hydrostatic curves plan , then using a series of formulas to get the ship's GM, is a normal method. The calculating GM is close to the real GM at small trimming situation, while there are big differences at large trimming state, therefore it is not safe for ship,especially in trim by head. The paper introduces a primitive way, with combination of the calculation functions of EXCEL, to roughly calculate ship's GM on an uneven keel and draw the curveas.
