三体船模型试验砰击载荷预报与分析(英文)

Slamming Load Forecasts and Analyses of a Trimaran Model Test

高速三体船是一个近些年发展起来的新船型,具有宽阔的甲板和双片体结构,良好的耐波性以及穿浪减阻能力。由于片体与主体之间的波浪非线性载荷缺乏精确的理论预报,对三体船展开物理实验来研究波浪载荷及砰击效应很具有必要性。文章在耐波性水池进行了三体船船体梁波浪弯矩的模型试验,结果表明三体船复杂的波浪载荷特性应当引起设计者的充分关注。

High speed trimaran is a recently developed type of ships, with a wider deck and two demi hulls, which possesses multiple abilities such as higher seakeeping, wave piercing with less resistance. Physical model tests of trimarans are of necessity for researching wave loads and slamming effects of the trimaran, since the wave interactions between main hull and demi hulls are nonlinear and lacking of precise theoretical forecasts. Hull girder bending moments induced by wave loads are presented of a trimaran model test in a seakeeping laboratory tank, results of which show that load characteristics of the trimaran is of complexity and should be fully paid attention by trimaran designers.
