摘要
为获得某散货船理论螺旋桨推进特性的数学表达进而建立其船机桨配合模型,选取与目标桨几何相似的日本AU系列五叶螺旋桨为研究对象,运用回归分析法计算得到其推进特性,并对计算结果进行修正,从而得出目标桨推进特性.根据该船试航报告,对所得推进特性进行验证.结果表明,该方法可行,所得推进特性符合实际情况.
To obtain the formula of propulsion behavior for the propeller theoretically designed to be installed on a bulk carri-er and establish the ship-engine-propeller matching model , a Japanese AU series propeller with 5 blades was chosen as study object , for it was geometrically similar to the target pro-peller.The regression analysis method was applied to get the propulsion behavior of the AU propeller , and then the result was corrected to get the propulsion behavior of the target pro-peller.The theoretically designed propeller behavior was ex-amined according to the sea trial report of the carrier .Results show that the method is feasible and the propulsion behavior conforms to the actual situation .
