基于层次分析法的增材制造路径选择方法

增材制造路径对于成型质量、打印效率等具有重要影响。针对由多重因素造成的增材制造路径选择困难等问题,提出基于层次分析法的增材制造路径选择方法。通过调研得到17个主要评价指标,剔除耦合指标后归类为6大子指标,构建增材制造路径评价指标体系;以成型性能、开发性能、应用性能为主要指标,以常见的6种增材制造路径为备选方案,构建具有双层指标的增材制造路径选择层次模型,应用层次分析法相对权数计算的层位传递原理,对路径选择的多层判断矩阵进行一致性检验,确定备选增材制造路径方案总排序。分析结果显示分形路径综合性能最佳。

Additive Manufacturing Path Selection Method Based on Analytic Hierarchy Process

Additive manufacturing paths have a significant impact on forming quality,printing efficiency,and more.Aiming at the difficulty of additive manufacturing path selection caused by multiple factors,an additive manufacturing path selection method based on analytic hierarchy process was proposed.17 main evaluation indexes of additive manufacturing path were obtained through survey.After excluding coupling indexes,they were classified into 6 sub-indexes,and the evaluation index system of additive manufacturing path was constructed.Taking the forming performance,development performance and application performance as the main indicators,and the six common additive manufacturing paths as the alternative schemes,a path selection hierarchical model of additive manufacturing with double-layer indicators was constructed.The consistency test of the multi-layer judgment matrix of the path selection was carried out by using the layer transfer principle of the relative weight calculation of the analytic hierarchy process,and the total ranking of the alternative additive manufacturing path schemes was determined.The analysis results show that the fractal path has the best comprehensive performance.
