高速船舶结构设计中流体冲击载荷的数值计算

On the mathematical calculation of the hydrodynamic slamming loading in designing the structure of the fast craft

本文采用混合欧拉－拉格朗日数值方法计算高速船舶砰击时的流体冲击载荷。计算与试验结果一致，能够反映高速船舶实际砰击状况的流体冲击载荷大小及其分布，这为进一步安全设计高速船舶结构提供了理论基础。

The composite Euler Lagrange mathematical calculation method is used in the paper to calculate the hydrodynamic slamming loading on the structure of the high speed craft. It is proved the calculation has full agreement with the test result, and it reflects the amplitude and distribution of this loading as well as actual slamming condition on the craft. It serves a theoretical basis for the safe designing of the hull structure of the high speed craft.
