| 摘 要： | 本文基于切片理论，计入船体运动时湿表面及其对船体流体动力性能的影响，提出了一种船舶在波浪中大幅度运动的工程估算方法，并通过对一系列６０船型计算，考虑了船舶在迎流中大幅度运动昱的运动特性、与波面的相对运动和船体瞬时受力。这一方法简单实用，对船舶方案设计有积极的意义。

| Abstract: | An engineering method for predicting the large amplitude motions of ships in waves is presented in the paper based on the commonly used strip theory with the extension of taking into account the instantaneous variation of the wetted hull surface during motions and its effects on the ship hydrodynamic characteristics. The method is examined on the large amplitude hull motions, the relative bow motions to waves and the instantaneous forces on the hull etc. for a ship of Series 60 in head seas. It is hoped that the present method can be widely used in the concept ship design stage due to its simplicity and efficiency. |
