摘　　要：通过敏感性分析方法确定了使船舶操纵运动敏感的干扰系数.文中采用模型试验方法测量了船舶在满载、半载和压载等6种装载状态下船舶的干扰系数值,并分析了吃水和纵倾对干扰系数的影响.之后,作者利用测量的干扰系数,以MMG数学模型模拟计算了船舶在6个装载状态的操纵性能,结果表明吃水和纵倾变化对操纵性的影响较大,不同装载状态船舶的操纵性能的研究将为船舶安全航行提供重要依据.The interaction coefficients of ship maneuvering are determined through sensitivity analysis. By model test, the interaction coefficients are measured based on 6 kinds of loading conditions such as full load, half load, and ballast etc. The effect of draft and pitching on the interaction coefficients are also analyzed. By the coefficients, the maneuvering performance under 6 kinds of loading conditions is calculated in the MMG model. The result shows that draft and pitching have larger effect on ship maneuvering. Researches of ship maneuvering in different loading conditions provide important foundation for safe sailing.
