摘　　要：为研究开阔水域中船舶对遇局面下的自动避碰方案,对对遇局面中两船会遇的不同阶段进行划分,在此基础上进一步分析实现船舶自动避碰需对会遇局面要素进行的定义和计算。提出使用船舶三自由度MMG水动力模型和平移中心椭圆船舶领域模型理论,研究对遇局面避碰要素数值化计算模型和不同阶段的自动避碰方案规划。仿真结果表明:三自由度MMG水动力模型精度能够满足研究和应用要求;基于二分法的数值计算模型能可靠、快速地收敛。研究成果能为最终实现船舶对遇局面下的自动避碰奠定坚实基础。The automatic collision avoidance decision-making for ships approaching each other head-on is studied. Encounter situation changes with the distance between ships so the process of approaching is divided into stages when processing. The elements describing encounter situation are defined. The elements are quantitatively determined according to the MMG three-degree-of-freedom hydrodynamic model of the ships and the theory that a ship needs an elliptical domain. The maneuver plan for each stage of approaching is worked out. Simulations prove that the hydrodynamic model is accurate enough for this application and the computing model based on the method of bisection is good for its rapid convergence and reliability. The research may advance the development of automatic collision avoidance equipment.
