摘　　要：仿真测试是验证智能船舶各项功能的重要手段,船舶操纵运动建模与仿真是实现复杂海域下多船智能避碰的关键理论基础。针对现阶段船舶操纵运动建模所需的水动力系数计算复杂且难以获取的问题,提出一种混合经验法,建立了现有回归公式的组合方法,构建了综合性能指标,通过仿真操纵试验对水动力系数组选优,并基于MATLAB研发了快速建模程序代码。结果表明:该方法能够在有限的船型参数下实现高效、便捷、自动化地生成给定船舶的操纵性运动模型,对智能船舶的仿真测试验证具有重要的工程实践意义。Simulation testing is an important means to verify the functions of intelligent ships.Ship maneuvering motion modeling and simulation is the key theoretical basis for the intelligent collision avoidance of multiple vessels in complex sea areas.To address the problem that the calculation of the hydrodynamic coefficients required for ship maneuvering modeling is complex and difficult to obtain,a hybrid empirical method is proposed,a combination method of the existing regression methods is established,the comprehensive performance indicators are constructed,the optimal hydrodynamic coefficients groups are selected by simulated maneuvering experiments,and a rapid modeling program code is developed based on MATLAB.The results show that,under limited ship parameters the proposed method can efficiently,conveniently,and automatically generate the maneuvering motion model of a given ship.The method is of important engineering practical significance for the simulation testing and verification of intelligent ships.
