剪切流作用下超大型浮体的非线性动力响应
本文研究了垂向速度呈指数形式分布的有旋剪切流作用下浮体的非线性动力特性。引入流函数构建控制方程和非线性边界条件。对于浮体为无限长板情形,运用同伦分析方法,得到收敛的近似解析解。结果表明,顺水剪切流使得波峰更尖锐、波谷更平坦,而顺水剪切流的作用则相反;同向的行进波和剪切流使得波速增加,而波流反向时波速减小。

剪切流作用下超大型浮体的非线性水弹性响应
本文研究了在剪切流和深水行进波的共同作用下超大型海洋浮体(VLFS)的非线性水弹性响应问题。针对垂向速度呈指数分布的有旋剪切流情形,提出引入流函数构建物理模型的方法,并运用不依赖于任何物理小参数的同伦分析方法(HAM)求得收敛的近似解析解。最后利用计算结果详细讨论了几种重要物理量对板的非线性水弹性响应的影响,我们发现指数剪切流与行进波同向时,涡量越大板的波形 …
