| 摘 要： | 若考虑船舶液（体）舱内自由液面对稳性的影响，对于非液货舱通常是按装载５０％舱容液体的固定值计算。当液舱（接）近满载时，许多船舶由于缺乏修正资料或方法，其影响值均被看作为零。事实上，对于那些设置有容量大、数量多的液舱的船舶，若将众多近满载液舱对稳性的影响进行叠加，其数值已不容忽视。本文通过数学推导，借助计算机模拟运算，结合计算实例，介绍了一种适应性较强的近满载液舱自由液面对稳性影响的计算方法，具有一定的实用价值。

| Abstract: | The free surface effect on stability is usually regarded as a fixed valueon the assumption that the tank is loaded to its half capacity. When a tank approachesits full capacity, the free surface effect is usually neglected owing to the lack of a correction methed. In fact, if the effects on stability of all such tanks are accumulated, as forthe ships with many liquid tanks, the result gets to the non-allowably negligibleextent.Based on the formula derivation, the results of computer simulation and a practical example offered, this paper introduces a quite widely applicable method for correctingthe free surface effect on stability in a liquid tank when it is approaching its fullcapacity. The method is of some practical worth. |
