全航速三维线性波浪载荷时域内数值计算研究

高速船舶波浪诱导载荷存在航速效应,波浪诱导船体垂向弯矩随航速增加而增加.针对某集装箱船采用三维时域全航速水动力分析理论预报集装箱船在波浪上的运动性能和剖面载荷,深入分析船体运动性能和剖面载荷的航速效应,得到船体纵荡、横荡,横摇和首摇以及船体扭转波浪弯矩航速效应显著,为船舶结构设计人员在波浪载荷的计算上有一定的参考.

Study the intra-domain numerical calculation at the 3D linear wave loads

The research study shows that the wave-induced loads increase with speed effects particular for the high-speed ship, it concludes that the vertical-bending moment increase with speeds. The intra-domain hydrodynamic analysis theory is used to predict wave-induced motion and section loads of a container ship. The motion and relevant section loads due to the speed effects are illustrated. The motion of heave, sway, roll, yaw and torsion moment due to speed is obvious. It offers some references for the designer...
