摘　　要：船舶在静水和波浪条件下的兴波运动是一种典型的非线性运动,为了提升船舶的动力性能,有必要系统性对船舶的兴波运动,尤其是兴波阻力等特性进行研究。数值分析和流体仿真是进行船舶和流场分析的重要工具,本文介绍了船舶兴波运动分析的数值分析基本理论,利用面元法和NAPA求解器,建立船舶的有限元模型,进行船舶兴波运动的仿真分析。The wave making motion of a ship in still water and waves is a typical nonlinear motion.In order to improve the dynamic performance of the ship,it is necessary to systematically study the wave making motion,especially the wave making resistance and other characteristics of the ship.Numerical analysis and fluid simulation are important tools for ship and flow field analysis.This paper introduces the basic theory of numerical analysis of ship wave making motion analysis,establishes the finite element model of ship by using panel method and NAPA solver,and carries out the simulation analysis of ship wave making motion.
