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.

Abstract. In order to implement spacecraft assembly based on MBD, this article proposes a method of structural process design based on 3D model. First, an Assembly Digital Mock-up (ADMU) is constructed. Second, we propose the way of assembly process design based on 3D structural process design scheme. Finally, the paper describes the application of the technology, and analyses the effect of the scheme during a satellite development. The technology and systems should be applied on other sophisticated products development, with some essential modifications.

Abstract. In order to implement spacecraft assembly based on MBD, this article proposes a method to construct datapackage automatically based on 3D model. First, an Assembly Digital Mock-up (ADMU) is constructed. Second, we propose the way of assembly process design based on 3D structural process design. Third, we construct the product data-package automatically based on the relationship among ADMU, the process files and production parameters Finally, the paper describes the application of the technology, and analyses the effect of the scheme during a satellite development. The technology and systems should be applied on other sophisticated products development, with some essential modifications.
