【摘要】 本文采用了正交试验方法研究肥大型船舶操纵性能。影响肥大型船舶操纵性的主要因素为船型参数ｄ／Ｌ、Ｂ／ｄ、Ｃｂ和舵面积系数对应上述诸因素分别选取三个位级，采用Ｌｇ（３４）正交表编排操纵性试验方案。对回转性、航向稳定性、转首性及淌航舵效诸衡准值的试验结果，按正交表计算各因子极差，示出趋势图，分析诸因素对操纵性的影响，并经对试验结果的回归处理，分别给出回转性、航向稳定性、转首性及淌航航效诸衡准值的估算公式。经实例计算表明，其计算值与试验结果是较一致的，因此给出的操纵性估算式可适用于肥大型船舶初步设计及航行性能的综合优化。更多还原

【Abstract】 The method of normal test is used to study V`LCC maneuvrability in this paper. They are major factors ofeffect, which are parameters of ship body d/L, B/d, Cb and rudder area coefficient upon VLCC maneuvrability. Three ragement classes are selected corresopding to the various factors as mentioned above, and projectsof test are arranged with the normal table Lg (34).The defference in limit value is calculated according to thenormal tables, respectively corresponding turning, yaw stability, course changing and coasting test results, and thetiend charts are shown, and various factors of effect upon maneuvrability are analyzed, and the estimate formula onturning ovality, yaw stability, course changing quality and rudder effect in coasting are given. These estimate formula are suitable for VLCC’s preliminary design, because calculating results accord with test results.更多还原
