摘　　要：潜体近水面航行时将受到波浪力的作用．其中二阶垂向平均力和二阶纵摇平均力矩有可能使潜体浮出水面，因此正确估算作用在潜体上的二阶平均波浪力．对近水面航行的潜体十分重要。本文利用波浪上任意低航速三维物体波浪力的计算方法来计算近水面潜体的波浪力并与国际上椭球计算结果、试验结果相比比较吻合，说明了本方法的实用性。A submarine travelling near the free sarface will suffer from the wave forces, in which the second ordermean wave forces in vertical direction and mean wave pitch moment may make the submarine emerge from the freesurface,so it is important to evaluate correctly the second order mean wave forces acting on the submarine travellingnear the free sarface. In this paper, using the numerical method for the calculation of wave forces acting on an arbitrary 3-D low speed body, the wave forces acting on the submarine travelling near the free surface are calculated,The results are compared with Newman's submerged spheroid, Feng' s results and test data ,It was shown that thepresent method is feasible.
