中文摘要：

螺旋桨的特征参数之间相互制约、影响,共同决定着螺旋桨的水动力、空泡以及振动等性能。本文以粒子群算法为工具,基于面元法理论,以4382型螺旋桨为模型桨,以侧斜、纵倾为优化变量对其进行优化设计。侧斜和纵倾采用贝塞尔曲线拟合方式进行综合考虑,以螺旋桨的效率为优化目标,对原桨及优化桨进行水动力性能分析。优化后桨叶的效率提高,压力分布得到改善,很好的抑制了空泡的发生。

英文摘要：

Characteristic parameters of a propeller restrict and interact with each other. They jointly determinehydrodynamics, cavitation, and vibration of a propeller. We perform its optimization design with particle swarm optimization （PS〇）algorithm as a tool,panel method,DTRC 4382 propeller as a model and skew and rake as optimization variables. Skew and rake are settled with Bessel curve fitting. We further analyze hydrodynamic property of original and optimized propellers with the efficiency of a propeller as an optimization objective. We increase the efficiency of a propeller, improve its pressure distribution, and well inhibit its cavitation.
