高速M型艇砰击载荷的模型试验研究

Model experimental investigation on slamming load of high-speed M-boat

本文根据相似理论,设计制作出一缩尺比λ=1:5的高速M型艇试验模型,并开展拖曳水池砰击测试试验,研究该M艇在规则波与不规则波2种情况不同工况下重心处垂向加速度与船底砰击压力的变化规律。本文讨论了波长对重心处垂向加速度的影响,并分析了不同航速下船底面砰击压力的大小与分布规律,为后续结构设计作支持。

In this study,according to similar theory,we designed and manufactured a test model of high-speed M-boat with a scale ratio ofλ=1:5,and carried out the towing tank slamming test to research the change law of the vertical acceleration at the center of gravity and the slamming pressure on the bottom of the boat under different conditions of regular wave and irregular wave.This study discussed the influence of wave length on vertical acceleration at center of gravity,analyzed the size and distribution of the slamming pressure on the bottom of the ship at different speeds,and support the subsequent structural design.
