浮体平衡稳定性的研究和应用

本文研究了几种简单的浮体和船体模型的稳定性,并对船体模型能承受的最大外力矩作了分析和计算,然后将这些分析和计算方法推广到任意形状的实际船体。这对船舶设计提供了一定的参考。本文对浮体稳定平衡的6种判据作了比较,指出各自的优点和局限性,以及相互关系。这对澄清有关的基本概念,改进该领域的教学和研究,会有所助益。

STUDY AND APPLICATION OF STABILITY OF EQUILIBRIUM OF FLOATING BODIES

Stability of equilibrium of several simple floating bodies and ship models was investigated, and the maximal allowed external torque for ship models was analyzed and calculated. The analysis and calculation procedure was generalized and applied to real ships of any shapes. This may help to improve ship design. 6 criteria for stable equilibrium of floating bodies were compared, and the advantage and limitation for each as well as their possible relations were pointed out. This helps to clarify some basic concepts and may benefit teaching and research in this field.
