三维实船首部结构入水砰击载荷预报

首先对三维回转体结构入水砰击问题进行仿真研究，并与文献中的试验结果进行对比，从而验证仿真方法计算三维结构入水砰击问题的可行性；其次研究三维实船首部入水砰击过程，分析实船首部结构砰击压力与入水速度、结构曲率的关系，并提出该首部结构的砰击压力预报公式。

Prediction of the slamming pressure on a 3-D structure of the bow into the water

Firstly, based on the method of numerical simulation, the water entry of 3-D Axisymmetric Structure was studied. Comparing the numerical simulation and model test results, verify the numerical simulation method was used to study the feasibility of the water problem. Secondly, the water entry of 3-D structure of the bow was studied, the relationship of the velocitythe curvature of the structure on the pressure of the bow entry into the water was studied, and a formula was provided to predict the slamming pressure of the bow structure.
