武器任意攻击角下舰艇的不沉性概率计算

Calculation of the Insinkability Probability for Ships in Any Attack Angles

摘要: 蒙特卡罗法作为计算舰艇不沉性概率的一种常用方法,在一维空间计算舰艇的失效概率中得到了广泛的应用。为了建立三维空间中的计算方法,在建立舰艇和武器攻击三维坐标系的基础上,把舰艇表面分割成很多个微小的三角形表面单元,运用蒙特卡罗法研究了武器任意攻击角度下舰艇不沉性概率计算的方法。最后,用型值表对实船进行三维坐标取值,计算该船在多次命中情况下的不沉性概率,并与一维方法的计算结果进行了比较分析。

Abstract: The method of Monte Carlo is usually used in calculating the insinkability probability of the warship, especially in one dimensional space. In order to develope a new method in three dimensional space, the warship＇s surface is divided in many small triangles. The paper study how to apply the method of Monte-Carlo to calculate the insinkability probability of the warship in any attack angle. In the end, the difference between the results of this method and the preceding method is compared and analyzed.
