面向复杂产品元件装配的流程建模与优化

针对产品元件装配流程中存在的聚类模块粒度过大、元件间干涉与冲突等问题,提出了面向复杂产品元件装配流程建模与优化方法。采用分析网络模型与模糊设计结构矩阵相耦合,对元件间的信息依赖关系进行定量化表示,其次运用传递闭包法求得具有自反性与对称性的模糊等价矩阵,基于截集阈值以及效用理论对复杂元件聚类划分,最后确定各元件模块的入出集,从而优化装配的执行顺序,提高产品的核心竞争力。以液压四足机器人腿部元件装配为例,验证了方法的有效性与可行性,为元件装配流程规划提供了新的设计思路。

Process Modeling and Optimization for Assembly of Complex Product Components

Aiming at the clustering module existing in the product component assembly process, the granularity of the clustering module is too large, and the interference and conflict between components. A method for modeling and optimizing the assembly process of complex product components is proposed. The analysis network model was coupled with the Fuzzy Design Structure Matrix to quantify the information dependence between components. And then the transitive closure method was used to obtain the fuzzy equivalence matrix with reflexivity and symmetry. Clustering of complex components based on cut-off thresholds and utility theory. Finally, the input and output sets of each component module were determined, thereby optimizing the execution order of the assembly. At the same time, improve the core competitiveness of products. Taking the assembly of the leg components of the hydraulic four-legged robot as an example, the validity and feasibility of the method are verified. New design ideas are provided for component assembly process planning.
