Research of the Technology and Application of Process Digital Mock-Up for Spacecraft Assembly Based on the MBD

Abstract

After representing the situation of the spacecraft assembly and the concept of Model Based Definition (MBD), the paper describes the method and principle of Assembly Digital Mock-up (ADMU), which achieved the transition of Engineering Bill of Material (EBOM) to Process Bill of Material (PBOM). With reconstructing EBOM and fulfilling structured Product Attribute, the paper gains the ADMU, which is the data source of spacecraft assembly process design based on 3D models.
