An analytical and experimental study of ship motions and capsizing in following seas has been conducted. For a ship having six degrees of freedom, the equations of motion are revealed based on Froude-Krylov hypothesis and slender body theory. Experiments have been carried out using a radio-controlled model in following waves generated in the towing tank. Comparisons of the experimentally observed motions and a theoretical prediction are presented. A time domain numerical simulation program for motions and capsizing has been used to investigate motions in sinusoidal waves. The results show good agreement with observed capsizing phenomena.In the interest of brevity, practical equations for ship motion and capsizing in following seas are derived. Simulations of capsizing are carried out by using Tasai's and Inoue's practical formulas for the hydrodynamic coefficients. Finally a material to discuss safety against capsizing is presented for novelty.

本文对船舶在顺浪中的运动和倾覆进行了分析和试验研究。针对具有六个自由度的船舶，基于弗劳德-克雷洛夫假设和细长体理论，推导出了船舶的运动方程。利用无线电遥控模型在拖曳水池中产生的随浪中进行了试验。实验观察到的运动和理论预测的比较。本文采用时域运动和倾覆数值模拟程序，研究了船舶在正弦波中的运动。计算结果与观测到的倾覆现象符合得很好。为简洁起见，本文导出了船舶在随浪中运动和倾覆的实用方程。利用Tasai和Inoue的水动力系数实用公式进行了倾覆模拟。最后，提出了一种讨论船舶抗倾覆安全性的新奇材料。
