摘 要: | 采用混合欧拉-拉格朗日数值方法计算高速船舶撞水时的流本冲击载荷,基于定理,采用线性边界元方法和非线性液面修正技术,考虑船舶的实际形状,数值模拟了肥大船型和球鼻艏船型的二维撞水过程,计算得到高速船舶实际撞水状况的流体冲击载荷大小及其分布,与实验结构吻合,为进一步安全设计高速船舶结构了理论基础。

Numerical Calculation of Hydrodynamic Impulsive Loading in Structural Design of High Speed Ship |
| |
Abstract: | The hydrodynamic impulsive loading on high speed ship is computed by using the mixed Euler Lagrange method. The revision of non linear deformation of water free surface and linear boundary element are used to simulate the two dimensional hydrodynamic inpulsive procedure of U shape and full bow ship. The computed results are quite close to the test data. The magnitude and distribution of hydrodynamic impulsive on high speed ship are computed, which gives a valuable refe rence for the design of high speed ship structure. |
