摘要 将优化算法应用在螺旋桨的设计中,通过建立数学模型对螺旋桨推进效率进行寻优。以影响螺旋桨推进效率的主要因素(桨叶数、直径大小、螺距比、盘面比)作为变量,进行数学建模,用多岛遗传算法对螺旋桨的推进效率进行优化计算。这样,改变螺旋桨的一部分参数就能直接得到最佳效率下的其他参数,而不需要进行繁琐的螺旋桨敞水性能图谱设计,对现代螺旋桨的设计有实用价值。 The algorithm is optimized for propeller design is this paper. Through the establishment of a mathematical model, propeller efficiency is optimized. Mathematical modeling with the main factors to affect the propeller efficiency (number of blades, diameter, pitch ratio, disk surface ratio) as variables. Multi-island genetic algorithm (MIGA) is used to optimize propulsive efficiency of the propeller. So we can obtain parameters after changes in some other parameters under optimum efficiency in order to cumbersome design propeller by open water performance spectrum which have practical value to modern propeller designs.
