基于模拟器的不同水深条件下VLCC旋回性仿真研究

A Research of Turning ability of VLCC under Different Water Depth Conditions based on Ship Manoeuvring Simulator

为探究VLCC旋回性能与水深的关系,利用船舶操纵模拟器,基于控制变量的原则,对VLCC在不同水深条件下的满舵旋回运动特性进行了仿真模拟,得出了VLCC在不同水深条件下的旋回数据,通过对数据的处理和分析得出了旋回相关参数与水深之间存在的内在联系。

In order to study the relationship between VLCC turning ability and water depth,the full rudder cycle motion of VLCC under different water depth conditions is simulated by using Ship Maneuvering Simulator based on Principle of Controlling Variables,and the turning data of VLCC under different water depth conditions are obtained.Through the analysis of the data,it can be seen that the turning headway,turning transverse distance and turning initial diameter of VLCC increase with water depth as a whole In the transition stage of the turning,the speed drop rate of VLCC is affected by the water depth.The greater the water depth is,the more intense the speed drops.
