| 摘 要： | 为了更准确地反映舰船破损后的稳性情况，有效辅助损管决策，探讨了舰船破损后最小初稳性高的计算方法，并和横稳性高的计算结果进行了比较．该方法可归结为平面几何图形的面积要素计算，采用封闭曲线积分法来求解使计算更具通用性．通过实例分析，证实了在水线面损失严重的情况下，与横稳性高相比，该计算方法在不影响计算速度的前提下提高了计算精度，更适合评估破损后的稳性状况．

| Abstract: | For stability condition evaluation and effective damage management in case of shipboard flooding emergency, this paper investigates a method to calculate minimal initial stability height of damaged warship, and contrasts the result with that of the transverse stability height. The proposed method adopts green formula to conduct integral calculation for the propose of generality, which boils down to the area element solution of plane geometry graphics. Comparing with the value of transverse stability height in the situation that the waterline area is lost seriously, the computational results indi- cate the proposed method is more applicable to evaluate the stability condition, which does not affect the calculation speed. |
