摘要

本文旨在利用模糊TOPSIS多准则决策(MCDM)技术,提出一种新的框架,对工业部件的增材制造(DfAM)设计策略进行优先排序和部署。然后将所提出的框架应用于汽车部件,并与现有设计结果进行了讨论和比较。设计/方法/方法高度与八个设计标准相关的DfAM设计方案已经确定,用于制定新的DfAM策略。利用模糊TOPSIS MCDM技术,通过逼近系数确定设计方案的优先顺序。基于模糊TOPSIS MCDM输出,将每个设计方案依次应用于汽车部件作为案例研究。在DfAM实现的每个阶段进行重新设计,而不影响功能。研究发现,在汽车零部件上成功实施该框架后,质量降低了43.84%,从0.429 kg降至0.241 kg。通过有限元分析验证了重新设计的有效性,其中von Mises应力小于材料的屈服应力。建议的DfAM框架和策略将有助于设计师,研发工程师,工业从业者,专家和顾问在任何工业组件上实施DfAM策略而不影响其功能。原创性/价值据作者所知,对汽车部件进行优先级排序和实施DfAM战略的想法是原创性贡献。

Prioritization and deployment of design for additive manufacturing strategies to an automotive component
Purpose This paper aims to propose a new framework on prioritizing and deployment of design for additive manufacturing (DfAM) strategies to an industrial component using Fuzzy TOPSIS multiple criteria decision-making (MCDM) techniques. The proposed framework is then applied to an automotive component, and the results are discussed and compared with existing design. Design/methodology/approach Eight DfAM design alternatives associated with eight design criteria have been identified for framing new DfAM strategies. The prioritization order of the design alternatives is identified by Fuzzy TOPSIS MCDM technique through its closeness coefficient. Based on Fuzzy TOPSIS MCDM output, each of the design alternatives is applied sequentially to an automobile component as a case study. Redesign is carried out at each stage of DfAM implementation without affecting the functionality. Findings On successful implementation of proposed framework to an automotive component, the mass is reduced by 43.84%, from 0.429 kg to 0.241 kg. The redesign is validated by finite element analysis, where von Mises stress is less than the yield stress of the material. Practical implications The proposed DfAM framework and strategies will be useful to designers, R&D engineers, industrial practitioners, experts and consultants for implementing DfAM strategies on any industrial component without impacting its functionality. Originality/value To the best of the authors’ knowledge, the idea of prioritization and implementation of DfAM strategies to an automotive component is the original contribution.

期刊介绍: Rapid Prototyping Journal concentrates on development in a manufacturing environment but covers applications in other areas, such as medicine and construction. All papers published in this field are scattered over a wide range of international publications, none of which actually specializes in this particular discipline, this journal is a vital resource for anyone involved in additive manufacturing. It draws together important refereed papers on all aspects of AM from distinguished sources all over the world, to give a truly international perspective on this dynamic and exciting area. -Benchmarking – certification and qualification in AM- Mass customisation in AM- Design for AM- Materials aspects- Reviews of processes/applications- CAD and other software aspects- Enhancement of existing processes- Integration with design process- Management implications- New AM processes- Novel applications of AM parts- AM for tooling- Medical applications- Reverse engineering in relation to AM- Additive & Subtractive hybrid manufacturing- Industrialisation
