摘　　要：针对迎浪随机波中集装箱船的参数激励横摇问题,本文主要研究船舶遭遇到的波浪条件与船舶参数激励横摇状态的相关性。基于C11集装箱船迎浪不规则波参数激励横摇实验,通过横摇幅值定义船舶发生显著参数激励横摇的时间段,然后通过波群方法分析船舶在横摇筛选段附近遭遇特征波群的特性。研究结果表明:船舶遭遇特征波群参数与船舶参数激励横摇的剧烈程度有较强的相关性,船舶遭遇特征波群数量和连长个数是船舶参数横摇剧烈程度的重要影响因素。This study investigates the correlation between ship-encountered wave groups and the status of ship parametric rolling while focusing on the parametric rolling of a container ship in random waves.The rolling amplitude is used to de-fine the time segment of significant parametric rolling based on the parametric excitation rolling test of the C11 container ship in irregular waves.The wave group method then analyzes the ship′s characteristics when it encounters characteristic wave groups during the selected parametric rolling segments.Results show a strong correlation between the ship-encoun-tered characteristic wave groups and the intensity of ship parametric rolling.The number and length of the runs of char-acteristic wave groups have a significant impact on the severity of ship parametric rolling in random seas.
