摘　　要：本文以ITTC推荐的两船标准模型为研究对象,开展顶浪规则波中两船标模波浪干扰的数值模拟及对比试验。基于求解N-S方程的雷诺时均方法,建立水平系泊约束下两船波浪干扰及六自由度运动计算方法。以试验模型和系泊参数为输入,进行典型波浪工况下两船波浪干扰数值模拟,获得标模六自由度运动、两船间波面升高及系泊拉力等参数的时历数据,并与水池试验结果展开对比。结果表明,对比工况下(波浪周期为1.5 s)模型的纵荡、垂荡、横摇、纵摇运动和两船间波面升高的计算与试验结果均吻合良好。相对而言,横荡和艏摇运动的计算与试验结果存在较为明显的误差,这是由于这些运动是两船间波系干扰与系泊约束耦合作用的结果,多因素模拟误差叠加导致了计算精度的降低。In this paper,numerical simulation and comparative verification tests of two ship models in heading regular waves,which was recommended by ITTC,were conducted.Based on the Reynolds time averaged method for solving the N-S equation,a calculation method of wave interference and 6DOF motions for two ships under horizontal mooring constraints was established.With the model and mooring parameters in the test taken as inputs,the numerical simulation of wave interference between the two ships under typical wave conditions was carried out.The time curves of 6DOF motions,wave surface rise between the two ships and mooring tension were obtained and compared with the results of model tests.The comparison shows that the motions of surge,heave,roll and pitch as well as the wave surface rise of the comparative conditions(wave period:1.5 s)are in good agreement with the test results.There are relatively large errors in motions of sway and yaw compared with the test results,because these motions result from the coupling of wave system interference between two ships and mooring constraints,and the superposition of multi-factor simulation errors reduces calculation accuracy.
