摘要： 摘要：为了研究大型船舶在斜浪中的水弹性效应及波浪载荷特征，选取矩形管状和圆形管状的组合梁作为分段模型载荷试验的龙骨梁,并合理设计组合管状龙骨梁，以保证模型垂向弯曲刚度和扭转刚度的纵向分布与实船相似.通过对分段模型在拖曳水池中不同航速、航向和海况下的规则波试验结果分析表明，分段模型能够较好地模拟船体弹性效应.同时,基于三维非线性水弹性理论对船舶在典型工况下的载荷响应进行了数值预测，与试验结果的对比表明,所用数值方法可以准确地计算大型船舶的波浪载荷.

Abstract: Abstract： Rectangular and cylindrical tubular backbones were used to serve as the backbones of a segmented model for wave load tests. The backbones were designed to meet the stiffness distribution requirements of the model in order to be similar to that of ship prototype. The model was tested in a towing tank in different sea states at different sailing conditions. The results indicate that the segmented model proposed in this paper is capable of simulating the elastic effects of ship sailing in oblique waves. In addition, the threedimensional nonlinear hydroelasticity theory was adopted to calculate the wave load responses of the ship sailing in oblique wave conditions. The comparison of the numerical results and the experimental results shows that the wave loads obtained by the two methods are in good agreement.
