| 摘 要： | 本文运用边界元法分析外飘和Ｕ型船体载面的砰击问题，在分析过程中自由液面采用完全非线性边界条件以及计算自由液面的大变形，而边界单元则采用线性单元假设。数值计算表明，针对二维楔形体常速入水的结果与已有的结果吻合得很好，具有外飘和Ｕ型特性的船体截面在入水砰击过程中其压力分布及其演变具有完全不同的特性。

| Abstract: | Boundary element method is used in this paper to calculate the slamming problem for flare andU-shaped ship hull sections. During the impact, the nonlinear free surface boundary conditiOn is satisfied. Thecalculated result from rigid wedge entering water is compared with the pub1ished data, and good agreement hasbeen found. The results for different ship hull sections show that impact feature complete1y depends on the typeof hull section. |
