船体后体形状对船舶操纵性的影响研究

On Influence of Stern Hull Form on Ship Maneuverability

在型线优化过程中,综合考虑阻力、操纵水动力性能,为能设计出综合性能优的船舶线型奠定基础。采用平面运动机构(PMM)进行某船F1A1以及F1A3两线型在设计吃水状态下的直航、斜航运动和摇首运动等试验,对两型船的阻力进行分析,回归得到相关的水动力系数,分析后体形状对船舶操纵水动力的影响,并通过数值模拟,分析两船的回转性、应舵性和航向纠偏能力。

The resistance and maneuverability of the ship are comprehensively considered during the hull form optimization, which can lay the foundation for the design of the hull form with the excellent overall performance. The tests of a ship with the hull form of F1A1 and F1A3 under the design draft are carried out by using the plane motion mechanism （PPM）, including the direct towed test, oblique towed test and pure yaw test. The resistance of both ships are then analyzed for the regression of the relevant hydrodynamic coefficients and the analysis of the influence of the aft shape on the ship maneuverability hydrodynamics. The turning ability, steering quality and yaw checking ability of both ships are also analyzed through the numerical simulation.
