【摘要】 本文通过两个实艇计算对比,阐明大型潜艇在总稳定性计算中会出现异常特性,归纳了异常后的变化规律,指出原有计算公式应作相应的改变。研究指出纵向刚度不足是出现异常的原因,分析了为什么纵向刚度不足会导致异常,确定了异常出现的判据,计算并绘制了异常区域的界限曲线。三个钛合金模型试验验证了异常特性的客观存在。更多还原

【Abstract】 By comparing of the stability calculation of two practical, submarines it is shown that unusual features will occur due to the insufficiency of longitudinal regidity. Some revised stability calculation formulae are suggested and a criterion for judging unusual phenomena is established and the Corresponding graphs are given. This study is proved by the experiments of three fine lathed titanium alloy models.更多还原
