| Abstract: | Based on the method of numerical simulation, the slamming process of rigid ship's bow structure is studied. The change of liquid level and the effects of velocity and curvature on the slamming pressure are studied. The dynamicre-sponse such as stress, deformation, and energy absorption of elastic bow structure is studied, and it has very importantsigni-ficance to optimize the ship's bow structure and verify the safety. |
