The invention discloses a wave load calculation method for a ship containing a moon pool, and relates to the technical field of ships, and the method comprises the steps: carrying out the discretization of a ship outboard wet surface, a moon pool wall wet surface, a moon pool inner liquid level, a ship outboard free liquid level and a sea area bottom surface grid of a fluid calculation domain where a three-dimensional ship model of the ship containing the moon pool is located, and carrying out the calculation of the wave load based on an RANKINE method; the boundary condition of the wet surface of the pool wall of the moon pool is added into the object plane boundary condition, and the boundary condition of the liquid level in the moon pool is added into the free liquid level boundary condition, so that a speed potential boundary integral equation is supplemented, the hydrodynamic pressure of the wet surface of the ship containing the moon pool can be solved, and then the ship motion and the wave load of the ship containing the moon pool can be solved. The technical vacancy of the industry is made up, and a more accurate evaluation method is provided for the wave load of the ship containing the moon pool.
本申请了一种含月池船舶的波浪载荷计算方法,涉及船舶技术领域,该方法对含月池船舶的三维船舶模型所在的流体计算域的船体舷外湿表面、月池池壁湿表面、月池内液面、船体舷外自由液面和海域底面网格离散后,基于RANKINE方法,在物面边界条件中加入月池池壁湿表面的边界条件,在自由液面边界条件中加入月池内液面的边界条件,从而补充了速度势边界积分方程,可求解含月池船舶的湿表面的水动压力,继而可以求解含月池船舶的船舶运动和波浪载荷,弥补了这一行业的技术空缺,为含月池船舶的波浪载荷提供了更准确的评估方法。
