| 摘 要： | 采用二维有限元法计算高速船垂向振动，船体结构部分采用二维有限元法计算，流体部分采用流体力学的二维边界元法计算，考虑了船体的变形，运用切片理论，可得船体的附连水质量，通过改变水下结构密度的方法，将附连水质量加在船体水下结构上，计算得到船体的固有频率，计算结果同实验值和Ｓｕｐｅｒｓａｐ计算结果进行了比较，表明本方法是有铲的合理的。

| Abstract: | The shiphull vertical vibration of a modern high speed ship is researched. By using two dimensional finite element method, the ship structure is calculated. By using hydrodynamic two dimensional boundary element method, the surrounding fluid considering the shiphull flexibility is analysed. By the strip theroy, the added mass is obtained. Compared to the results of literature and Supersap program, it is shown that the method presented here is efficient and reasonable. |
