最优化方法在船舶运动预报中的应用

在采用时域方法求解斜浪中船舶的水平运动响应时，计算中出现的横向“漂移”现象一直是困扰工程师们的难点。作者引入最优化理论，提出了一种预报船舶运动的新方法，理论分析和数值计算结果表明，采用本文方法预报船舶在波浪中的稳态运动响应是可行的，且能有效地消除船舶水平运动响应计算中的发散现象。

Application of Optimization in Predicting Ship Motions

The drifting problem emerged when solving the horizontal motion responses of a ship traveling in the oblique waves in the time domain,which used to annoy the engineers for many years.The authors of this paper presented a new method for predicting the motion responses of ships by introducing the optimization theory.This method proved to be effective in eliminating the drifting problem by theoretical formulation and numerical analysis.
