大型船舶出坞过程仿真

Ship Undocking Maneuvering Simulation

根据大型船舶出坞的要求,建立了船舶出坞过程仿真数学模型,包括船舶出坞操纵的基本模型、水动力模型以及拖轮等的作用力计算模型。编程计算了大型船舶出坞过程中的环境载荷,对大型船舶出坞过程进行仿真预报。以17.5万吨好望角型散货船为例,计算了该船受到的总的环境外载荷,并对该船出坞运动轨迹进行仿真预报。

According to the demands of a super large ship undocking, this paper discusses a mathematical model of ship maneuvering simulation in detail. It includes the fundamental model,hydrodynamic force model,force and moment model of wind,wave,current,tugs and ship lines.This paper calculates the forces of 175000 DWT bulk carrier in undocking,and simulates its undocking movement trace.
