摘要
传统船舶动力学理论是基于刚体假设之上的，本文表明如何用水弹性力学方法计算这种波浪响应。这种广义理论将结构理论、流体动力学理论、海洋学和统计理论综合于一体，它既可用于船舶，也可用于一般海洋工程结构物。某驱逐舰典型对称响应的计算结果表明，在低阶模态对称运动下，切片理论可以很好地满足实际强度分析的需要。
The traditional dynamical theory of ship has been founded largely on the assumption of rigidity. This paper shows how the wave responses of a ship can be calculated by approach of hydroelasticity. This general treatment unifies the techniques of structural theory, hydrodynamics, oceanography and statistical theory. The principles are applicable to offshore structures in general as well as to ships. The typical results of symmetric responses of a destroyer show that strip theory can cope adequately with the lower modes of symmetric motion and well suffice for practical strength analysis.
