摘　　要：应用数值方法对多艘舰船进行水下非接触爆炸的数值试验,通过对各种工况下的计算可得水面舰船在我国现行的损伤评估体系下的破坏半径、临界半径和安全半径,据此可知水下爆炸对舰船破坏的一些特征。从更安全角度考虑对各评估体系的损伤等级定义提出了局部修正,并形成协调标准,绘制出舰船在该标准下的等损伤面包络图。依据算得不同舰船的安全半径,拟合出水面舰船安全半径的计算公式。计算公式预测值与实船试验数据吻合较好,可为舰船生命力的评估提供参考。In this paper the numerical method is used to do warship＇s numerical trial of underwater non-contact explosion. The damage radius, critical radius and safety radius of surface ship are computed with this method in accordance with several current evaluation criteria of damage grade in our country, some characteristics are discovered based on the result. By contrast with the damage grade of different criteria, the definition of damage radius in different criterion is amended making those current criteria more safe. A harmonious criterion is formed and envelope diagrams of equal damage are drawn under this criteria. The formula is fitted according to the safety radii of surface ship. The prediction of the formula has a good accordance with the data of warship trial. So the formula can be refered to estimate the vitality of warships.
