摘要
为实现工程船定位和控位快速模拟仿真,以45000载重吨海洋工程船为例,采用均匀设计试验方法,确定深海船舶工作的不同工况组合,基于Ansys-Aqwa软件对该船的深海锚泊动态响应进行仿真分析。对仿真结果进行回归分析处理,得到船舶位移和锚索张力与锚索长度和环境载荷(风、浪、流)之间的数学响应模型。对位移数学响应模型进行求反函数处理,获取船舶控位调整锚索长度的方法,为深海锚泊软件仿真系统提供模型支撑。
In order to achieve the engineering ship positioning and control fast simulation,taking 45000 DWT ocean engineering ships as an example,adopting the uniform design experiment method,different operating conditions combination is determined.The deep-sea mooring dynamic response simulation of the engineering ship is analyzed based on Ansys-Aqwa software.The regression analysis is performed on the simulation results to obtain the mathematical response model between ship displacement and anchor cable tension,anchor cable length,and environmental load(wind,wave and current).The inverse function processing is performed on the displacement mathematical response model,and the method of obtaining the ship’s position and adjusting the length of the anchor cable is provided to provide model support for the deep sea anchoring software simulation system.
