甲板上浪和冲击载荷的数值模拟

Numerical Simulations for Green Water Running on Deck and Impact Loads

中文摘要英文摘要

在二维数值水池中特别引进了动网格技术,分别模拟了迎浪中固定FPSO和横浪中振荡船舶的甲板上浪。数值结果与试验吻合良好。表明本文提出的方法和数值处理技术可用于实际的甲板上浪现象的模拟,估算和分析甲板上浪在浮式结构物上的冲击力。对进而指导船舶设计和优化,特别是船首及其结构设计,有重要的意义。其机理也有助于船员在航行过程中有效地避免严重的甲板上浪发生。

technique of dynamic mesh is specially introduced in a 2-D numerical wave tank to simulate the green water incident on a fixed FPSO model in head waves and oscillating vessels in beam sea conditions, respectively. Numerical results agree well with the corresponding experimental ones. It indicates the present numerical scheme and method can be used to actually simulate the phenomenon of green water on deck, and to predict and analyze the impact forces on floating structures due to green water. It is of great significance to further guide the ship design and optimization, especially for ship bow and its strength design. The mechanism may also help seaman to impose operation restrictions to avoid severe green water incidents.
