摘　　要：为便于将海上船舶避碰问题利用计算机进行研究,需要把船舶的运动特点用数字形式进行模拟,把风、流和浪等问题一起讨论并寻找最合适的数学表达式模拟出船舶航行的状态,这样才便于研究海上船舶避碰的问题。现以六面体船舶为典型特征来进行研究,叠加了矢量风、流和浪的数学表达式,并利用高阶Runge-Kutta推导微分方程进行高精度仿真船舶海上航行的特征,并建立相应的数学模型以便于讨论船舶避碰问题。In order to facilitate the research for preventing collsions at sea,it can be studied via computers,which involves digital simulation of ship motion characteristics,considerations of wind,current and waves,as well as the layout of the most appropriate mathematical expressions to simulate the ship moving state.Based on the typical features of hexahedral ship,this paper researches superposing vector wind,current and waves,precisely simulating the characteristics of ship＇s navigation at sea by high-order Runge-Kutta differential equation,establishing corresponding mathematical model,studies the prevention of ships＇s collisions at sea.
