中文摘要：

为了分析锥形浮子入水冲击的规律,基于Fluent软件采用动网格技术,对斜升角分别为30°、45°、60°的锥形浮子入水冲击过程进行了模拟仿真.通过分析压力和速度数据,发现在锥形浮子入水瞬间水面对浮子产生的冲击十分巨大;压力峰值先于冲击载荷峰值出现,而且两峰值之间的时间间隔随锥体斜升角的增大而增大.

英文摘要：

In order to analyze the rules of tbe water impact, numerical simulation of water entry impact of conical buoy with different deadrise of 30°, 45°, 60°were carried out based on FLUENT software, using dynamic mesh. With the analysis of the pressure and velocity data, it was found that the impact on the buoy at the water-entry moment is very huge. The peak value of the pressure appears ahead of that of the impact load, and the time interval between the two peaks increases in the cone angle. The results have reference value for the optimization design and reducing the impact damage of the buoy.
