最优化方法在船舶运动预报中的应用

Application of Optimization in Predicting Ship Motions

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 .

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.
