船舶在波浪中运动的非线性耦合方程及其稳态解

Nonlinear coupling equations and steady-state solution for ship moving in regular sea

在船舶与海洋这个自制系统中，把船舶的运动以及船舶与海洋之间的 相互作用，表示成能量形式的Ｌａｇｒａｎｇｅ函数，用Ｈａｍｉｌｔｏｎ方法推导出船舶 在波浪中三维空间运动的非线性耦合方程，然后用多自由度非线性摄动法 中的多尺度法求解船舶运动方程的稳态解．

Considering the ship and sea to be a single dynamic system, the authors can describe the interaction between a ship and sea by Lagrange's energy function. With Hamilton's method, the nonlinear coupling equations for ship motion in regular sea with all six degrees of freedom can be formulated.
