【摘要】 采用数学模型进行船舶操纵性模拟是常用的方法，但喷水推进船航速高、回转时横倾大，还会出现侧滑现象，有必要开展操纵性水动力影响的研究。论文采用大振幅平面运动机构开展了高速单体喷水推进船的斜航、纯横荡和纯摇首运动的模型试验，在不同航速下对带有喷水推进的船体和裸船体进行水动力测试，分析了与上述运动相关的水动力导数。试验表明，高航速引起的船舶升沉和纵倾等运动姿态较大的变化以及喷水推进作用下船体产生的“虚尾”，使操纵性水动力导数受到很大影响。还发现该船在两个试验航速下都不具有航向稳定性，在总体设计时需要考虑初始尾倾，以消除喷水推进产生的不利影响，必要时需增加呆木或稳定鳍，用于改善航向稳定性。更多还原

【Abstract】 In this article, tests with planar motion mechanism(PMM) for a high speed ship with water-jet propulsion was carried out to obtain hydrodynamics coefficients, including oblique test, pure sway test and pure yaw test for the hull with water-jet propulsion and bare hull at various ship speeds. It is shown that sinkage and trim are greatly changed because of the effect of high speed, and the course keeping ability of the ship does not meet the requirement. Some advice is made in the initial design period, where the stern trim,dead wood and fin should be taken into account to increase the course keeping ability.更多还原
