Abstract
The functions, applications, developments and current application mode of IDS2.x system are generally introduced in this paper. Then the development mode of spacecraft based on IDS2.x system is described. The existing problems especially the information redundancy of mechanical interface and their effects are pointed out. A new solution is proposed by developing 3D-IDS system. The central functions of 3D-IDS system are shown in this study. A new application mode of 3D-IDS system is explored and described by showing how to fill in, countersign and apply with 3D-IDS file. The 2D drawing and sketch are removed from 3D-IDS system to avoid information redundancy of mechanical interface. The consistency between 3D model and the parameters of IDS file can be guaranteed by the interface tool. The efficiency of filling in, countersigning and applying has been improved significantly, which greatly promotes the coordination and total efficiency of spacecraft system design departments and equipment design departments.
Highlights
IDS is the abbreviation of Interface Data Sheet in this paper
There are some disadvantages in the current application mode of IDS system, which are increasingly unable to meet the requirements of automation, consistency and reliability
From manual filling in parameter values, pasting equipment sketch, submitting 3D models, submitting 2D drawings and manual comparison, it has been transformed into standardized setting of model-based parameter, information reading and submitting based on interface tool. 3D model design of spacecraft equipment should be carried out according to the 3D model requirements of spacecraft equipment
Summary
IDS file is a kind of important file which is used to control the mechanical, electrical and thermal interfaces between system, subsystem and equipment in spacecraft development. IDS files are the basis of spacecraft development engineering [1, 2, 3]. As the number of spacecraft development tasks increased continuously, it was becoming more and more difficult to meet the needs for manual management of IDS files. The existing functions of IDS system meet the needs of spacecraft development to some extent, and realize the unified management of top-level data source. Some problems cannot be fundamentally solved on IDS v2.x version These problems focus on the mechanical interface. In IDS files, the mechanical interface includes parameter information, sketch, 2D drawing and 3D model.
