Abstract

This paper proposes a multi-objective optimization design method for shaftless rim-driven thruster (RDT) based on the ISIGHT platform. The pitch ratio, the blade area ratio and the advance coefficient of RDT were considered as the design optimization variables, the thrust and efficiency of the RDT were the optimization objectives. The multi-objective optimization design method was based on the surrogate module and the optimization module in the ISIGHT platform. Two analytical methods (response surface methodology (RSM) and radial basis function Model (RBF)) were used to build the surrogate model. The Muti-Island GA optimization algorithm was adopted in the optimization module. The paper indicates that both RSM model and RBF model are feasible to build the surrogate model, the RBF model has better accuracy and reliability than RSM model. The blade obtained by RBF method has larger thrust and smaller torque than that of the blade obtained by RSM method. For the large advance coefficient ( J > 0.6), the efficiency of the blade obtained by RBF method is slightly higher than that of the blade obtained by RSM method.

无轴轮辋驱动推力器多目标优化设计

提出了一种基于ISIGHT平台的无轴轮辋驱动推力器(RDT)多目标优化设计方法。以螺距比、叶面积比和RDT推进系数为设计优化变量，以RDT推力和效率为优化目标。基于ISIGHT平台的代理模块和优化模块，提出了多目标优化设计方法。采用响应面法(RSM)和径向基函数模型(RBF)两种分析方法建立代理模型。优化模块采用多岛遗传优化算法。研究表明，RSM模型和RBF模型都可以建立代理模型，RBF模型比RSM模型具有更高的精度和可靠性。与RSM法相比，RBF法得到的叶片具有更大的推力和更小的扭矩。对于较大的推进系数(J > 0.6)， RBF法得到的叶片效率略高于RSM法得到的叶片效率。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
