| 摘 要： | 本文应用三维势流理论的水动力软件AQWA分析一种新型工程船舶在波浪中的运动响应,新型船为改造的波兰中型集装箱船B-573,设计搭载Pram型艉和POD吊舱式推进系统的新型海工船.本文计算此船在规则波中不同浪向角条件下的六个自由度的频域和时域的运动响应,得到在不同浪向角下船体的响应振幅算子RAO,计算船舶顺浪下不同船速的垂荡RAO以及纵荡、垂荡和纵摇三个自由度的一阶、二阶波浪力,分析结果显示该新船型具有良好的耐波性.

| Abstract: | The hydrodynamic software AQWA withthree-dimensional potential flow theory is used to analyze the motion response of a new type ocean engineering ship in waves. The new type ocean engineering ship is a modified Poland container ship B-573, which is designed to carry a Pram-stern and POD propulsion. In this paper, the motion response of the ship in six degrees of freedom iscalculated in the frequency domain and time domain under wave encounterangles. The response amplitude operator (RAO) inwave encounter angles, the heaving RAO in following waves in different ship velocity, the first-order and second-order wave force in the surging, heaving andpitching conditions are obtained to show the well seakeeping of the new type ship. |
