A Parameterized 3D Layout Design Method for Satellite

Abstract

Satellites equipment three-dimensional (3D) layout design is based on 2D schematic drawings and files. It leads to a problem that extracting input data and creating the assembly constraints in the 3D environment bring a large workload, meanwhile the layout result couldn't build a direct relationship with the input data automatically. A layout method driven by parameterized data is proposed in this study. By the means of model-based definition (MBD) and CATIA development, rapid design from the electrical schematic of the satellite to 3D layout is realized. Firstly, the input data are parameterized to XML format. And then, parsing the information of XML in by CATIA interface, the 3D model of equipment in server can be loaded automatically in CATIA workspace and the electrical connection of equipment can be displayed visually. Then using the algorithm of cabin surface capture we developed, equipment can capture the cabin surface intelligently and the assembly constraint can be created automatically. This method can realize the direct mapping of the input data to the satellite equipment 3D layout design. Meanwhile, the real-time update of layout status can realize the review of the design integrity, which can decrease some checking labor. Finally, this method is applied to a typical satellite equipment 3D layout design, and the result shows that it can effectively improve the automation and efficiency of the design.
