Spacecraft Assembly Process Bill of Material Construction Technology For Single-Piece Production

Abstract

Abstract. For the spacecraft assembly Process Bill of Material (PBOM) traditional construction technology, the product assembly relationship, product assembly information are not visual for spacecraft assembly and integration department, leading to the manual PBOM construction by using Product Data Management (PDM) system, which is inefficient and unreliable. This paper sorts all spacecraft products into seven Primary Product and others are Affiliated Product. Then this paper proposes the rules of PBOM automatic construction technology, which are Product Types mapping rule, assembly constraint rule and geometric rule, and introduces the PBOM automatic construction principle and workflow based on Pro/E. Finally, according to a real satellite manufacture, this paper describes the improved efficiency and reliability of the software developed with the technology, realizes the import into the PDM system, and analyzes the fault of the technology.
