| 摘 要： | 船舶在航行时发生砰击是一种高度非线性的物理现象。本文基于势流理论Rankine源法，研究用时域非线性方法计算船舶运动响应，获得船波垂向相对运动速度；并选取合适的砰击压力系数，计算船舶砰击载荷。最后用该方法评估了一艘集装箱船艏部砰击强度，验证了该方法的合理性。

| Abstract: | Slamming is a highly nonlinear physical phenomena during ship navigation. Based on Rankine method of the potential flow theory, the paper researched calculating the motion of vessel with the time domain nonlinear analyze method, the relative vertical velocity between water and hull is obtained. Then, selecting appropriate pressure coefficient, and calculating slamming loads of vessel. At last, the method is applied to a container ship to verify its rationality in assessing slamming strength of ship bow structure. |
