目的-在电磁设备的开发中,多目标拓扑优化是有效的,以获得不同的设计候选产品模型。然而,多目标拓扑优化还没有广泛地进行,因为它是很难得到的工程实现的形状,由于大的搜索空间。本文的目的是提出一种新的多目标拓扑优化方法。设计/方法/方法-本文提出了一种新的多目标拓扑优化方法,其中免疫算法被修改为多目标优化和形状修改过程的基础上,空间滤波。结果-本方法表明,更好的帕累托解决方案,可以找到与传统方法相比。独创性/价值-提出了一种新的有效的多目标拓扑优化方法。这种方法可以使生产模型的设计候选者多样化。
Purpose– In the development of electromagnetic devices, multiobjective topology optimisation is effective to obtain diverse design candidates for production models. However, multiobjective topology optimisation has not widely been performed because it is difficult to obtain resultant shapes for engineering realisation due to large search spaces. The purpose of this paper is to present a new multiobjective topology optimisation method.Design/methodology/approach– This paper presents a new multiobjective topology optimisation method in which the Immune Algorithm is modified for multiobjecrive optimisation and a shape modification process based on spatial filtering is employed.Findings– The present method shows that better Pareto solutions can be found in comparison with the conventional methods.Originality/value– A new effective multiobjective topology optimisation is presented. This method enables to diverse design candidates for production models.
