摘要
采用损失浮力法和增加载荷法相结合的方法给出了舰船破损后出现负初稳性时的静稳性曲线计算方法,自由液面对静稳性曲线的修正采用直接计算法.分析了上层舱室积水是舰船破损后出现负初稳性的主要原因,根据破损后静稳性曲线的类型探讨了舰船破损后出现负初稳性时应采用先恢复稳性然后平衡舰体的扶正方法.通过对某舰船的实例扶正计算,分析了恢复稳性时应采取的合理扶正措施,即要先考虑上层舱室积水的排除.
Combining the lost buoyancy method with the added weight one, the calculating methods of curves of statical stability are presented when the damaged warships＇ metacentric height is negative. Direct calculation method is adopted to correct the effect of the free surface on curves of statical stability. It is analyzed that the main reasons for negative metacentric height are seepers of cabin in the superstructure. According to the types of curves of statical stability, the righting methods are discussed. It is suggested that the stability should be restored first and then the warship balanced. Through the calculation of a warship, the reasonable measures for restoring stability are presented, the primary measure of which is to discharge the seepers of cabin in the superstructure.
