In this paper, the 3800 PCTC ro-ro ship is taken as the research object, and proposes a CFD prediction method for wave slamming load of bow-flipping ships under the action of regular waves. Based on the CFD theory, a three-dimensional wave slamming numerical pool model is established and verified. Based on the design sea state and limit sea state of Lloyd's Register of Shipping, three groups of low, medium and high calculation sea states are designed. Based on the CFD prediction method of the wave slamming load of the bow-flipping ship under the action of regular waves, the slamming load and the relative velocity of the ship wave when the slamming occurs are obtained; for the slamming load and the relative velocity characteristics of the ship wave under different wave sea conditions Non-linear distribution is discussed.
