基于泰勒展开边界元法的近水面潜艇垂向二阶波浪力（矩）计算
Calculation of vertical second-order drift loads on a submarine floating near the free water surface based on Taylor expansion boundary element method
摘要
Abstract
A submarine traveling near the free water surface experiences difficulty in depth control. Thus, the verti-cal second-order mean force and moment acting on the submarine were studied. One-order Taylor expansion bound-ary element method ( TEBEM) is used to improve the solution accuracy of the tangential induced velocity. This method keeps the first-order derivative for the dipole strength of the border integral equation and then takes the two tangential derivatives with respect to the field points on the boundary to form the closed equations in the third formu-la of the Green function. The velocity potential and the tangential induced velocity along object surface can be solved directly. This method was applied to calculate the vertical second-order drift loads of a submerged spheroid in head seas. The results show good agreement with previous numerical solutions. The vertical second-order drift loads of a submarine model were also calculated. TEBEM was found to achieve higher accuracy and quick convergence.关键词
