船舶破损双舱室强制横摇进水试验研究

Experimental Study on Forced Roll Intake of Damaged Twin Compartment

文中基于自主设计的强制横摇运动装置,完成船舶破损双舱室强制横摇进水试验,针对不同的船舶双舱室吃水、横摇振幅以及横摇周期三个影响因素,制定了75种试验工况并进行了大量重复性试验.试验测量得到的船舶双舱室内部水深时历曲线经平滑后与数值模拟所得图线趋势吻合.对比分析所有工况下图线,结果表明:船舶双舱室内部达到最大水深所需的时间基本与横摇振幅无关,受横摇频率影响,且第二舱室内达到最大水深的时间随船舶双舱室吃水的增加而明显减小.

Based on the self-designed forced rolling motion device,the forced rolling water entry test of damaged twin compartment was completed.According to the three influencing factors of different twin compartment draught,rolling amplitude and rolling period,75 test conditions were formulated and a large number of repetitive tests were carried out.After smoothing,the time-history curve of the water depth in the twin cabins obtained by experimental measurement is consistent with the trend of the graph obtained by numerical simulation.Comparing and analyzing the graphs under all working conditions,the results show that the time required to reach the maximum water depth in the twin compartment is basically independent of the rolling amplitude,but affected by the rolling frequency,and the time to reach the maximum water depth in the second cabin decreases obviously with the increase of the draft in the twin compartment.
