Research on Application of Digital Assembly Technology based on MBD in Spacecraft Field

Abstract

With the development of technology based on MBD, three-dimensional model has already been the sole basis during spacecraft assembly process, three-dimensional process design technology on MBD has all-around been applied in spacecraft assembly field. On the base of the five key technology which include digital assembly process design, visualization of three-dimensional process, simulation verification of three-dimensional assembly process, three-dimensional work instruction browsing and digital inspection, spacecraft assembly has realized the transformation from two-dimensional process design system to three-dimensional process design system. The digital assembly technology on MBD has thoroughly changed the spacecraft assembly flow. Through the implement of three-dimensional process design technology, the process design results are transferred to the workshop assembly site in the form of three-dimensional assembly instruction, improving the working environment of the production site, the level of spacecraft assembly is improved.
