以保障船舶以既定航线航行为目的,研究基于可视化编程环境的船舶航行参数优化方法。该方法将Dynamo参数化设计平台作为船舶航行参数优化的可视化编程环境,并从船舶航行时航向控制参数和航行速度参数角度出发,分别构建船舶航行航向控制参数优化模型和船舶航行航速优化模型。分别设置2个模型的约束条件,依据约束条件求解2个模型,得到最佳船舶航向控制参数和航行速度参数。将这些参数输入到可视化编程环境Dynamo参数化设计平台内,该平台启动船舶参数驱动程序代码,通过Revit软件呈现船舶航行参数优化的可视化场景。实验表明,该方法应用后可保障船舶沿着既定航线航行,降低船舶舵角变化区间,应用效果较好。

In order to ensure the ship’s navigation behavior on the given route, the optimization method of ship navigation parameters based on visual programming environment is studied. In this method, Dynamo parametric design platform is used as a visual programming environment for ship navigation parameter optimization;From the point of view of the ship’s course control parameters and navigation speed parameters during navigation, the ship’s course control parameter optimization model and the ship’s navigation speed optimization model are constructed respectively, and the constraints of the two models are set respectively. According to the constraints, the two models are solved to obtain the best ship’s course control parameters and navigation speed parameters;These parameters are input into the visual programming environment Dynamo parametric design platform, which starts the ship parameter driver code and presents the visual scene of ship navigation parameter optimization through Revit software. The experiment shows that the method can ensure the ship to navigate along the established route, reduce the variation range of rudder angle, and has a good application effect.
