| 摘 要： | 本文用表面奇点分布法对物体的水中弹道进行了分析和计算。研究表明,物体所受的水动力必须和刚体运动方程耦合求解才能得到收敛的结果。文中还对极高或极低 F_r 数情况下的物体水中运动进行了讨论。最后给出了算例。

| Abstract: | Theoretical analysis and numerical procedure for predicting the underwater trajectory of a body by means of singularity distribution on its surface have been investigated in the present paper.It is shown that the hydrodynamic force equations must be coupled with the body motion equations and solved simultaneously in order to obtain convergent results.A modified method has been developed for solving the problems involving a free surface when the Fr number is extremely large or low. Computational results are also given. |
