论文摘要
支架是飞机制造和设计中的重要组成部分，将零件融合在一起，支撑重量，握住电线和加强接头。每架飞机都使用了数百或数千个独特的支架，但是制造大量不同的支架效率低下且昂贵。幸运的是，许多所谓的“不同”括号实际上非常相似甚至相同。在此手稿中，我们提出了一个数据驱动的框架，该框架是基于括号数据的层次聚类来构建来自当前括号的大目录的相对较小的代表性括号。我们发现，对于现代商用飞机，可以将整个支架降低30 \％，同时仍然充分描述了一半的测试套件。这种方法基于设计一种内部产品，该产品量化了两个括号之间的多目标相似性，即两个括号是内部产品的“胸罩”和“ ket”。尽管我们证明了这种算法以减少航空航天制造中的支架数量，但通常可以应用于任何大规模的组件标准化工作。
Brackets are an essential component in aircraft manufacture and design, joining parts together, supporting weight, holding wires, and strengthening joints. Hundreds or thousands of unique brackets are used in every aircraft, but manufacturing a large number of distinct brackets is inefficient and expensive. Fortunately, many so-called "different" brackets are in fact very similar or even identical to each other. In this manuscript, we present a data-driven framework for constructing a comparatively small group of representative brackets from a large catalog of current brackets, based on hierarchical clustering of bracket data. We find that for a modern commercial aircraft, the full set of brackets can be reduced by 30\% while still describing half of the test set sufficiently accurately. This approach is based on designing an inner product that quantifies a multi-objective similarity between two brackets, which are the "bra" and the "ket" of the inner product. Although we demonstrate this algorithm to reduce the number of brackets in aerospace manufacturing, it may be generally applied to any large-scale component standardization effort.
