AQWA本文利用 软件对两船并行补给时的耐波性能进行分析,并将时域分析结果利用相关函数的方法进行反推,验证了谱分析的正确性,同RAO时也证明了 函数的可靠性。通过对耐波性的分析,得出以下主要结论: 1)在两船六自由度运动中,垂荡和横摇的响应幅值较大,对补给过程会有显著影响。2)在同一浪向下,与单船的六自由度运动幅值相比,两船间的水动力干扰作用明显,在某些频率下运动幅值会增大,尤其是垂荡和横摇运动。3)根据规则波下响应幅值的对比可看出,波Weather side浪从 入射时的运动响应幅值要大于Lee side从 入射时的情况。谱分析也有同样的规0° ~180°律,对接收船而言, 浪向的有义值大-180°~0° 0°~于 浪向的有义值;对补给船而言, 180° -180°~0°浪向的有义值要小于 浪向的有义值。这是由在斜浪和横浪时两船间相互的遮蔽效应所引起的。4 )时域运动计算出的有义值与谱分析计算的有义值吻合较好,说明时域分析准确可靠,同时3也符合结论 )的叙述。
