摘要
砰击是船舶航行过程中发生的一种高度非线性的物理现象。超大型集装箱船为了获得较大的甲板面积,通常在艏部具有较大的外飘角,高速航行时遇到风浪很有可能发生砰击现象。本文介绍了一种船体外飘砰击压力的计算方法,首先计算二维剖面的砰击压力,之后拓展到三维船体外表面以获得其砰击压力分布。该方法对于船体结构设计和结构安全性评估具有重要的指导意义。
The slamming phenomenon is a violent impact of the hull of a ship on the free surface of the sea,which is highly non-linear.For ultra-large container ship,the fore shape is designed of great flare angle to obtain large deck area and it is of great possibility to be suffered to slamming impact in sea-going condition.The article introduces a calculation method for the slamming pressure of bow-flare.First the two dimensional sectional slamming pressure is calculated and then the three dimensional slamming pressure is involved to gain the slamming pressure distribution.It is of great significance for scantling design and safety assessment of the hull structure.
