航天器仿真与测试一体化系统

Integrated System for Spacecraft Simulation and Test

提出了一种航天器仿真与测试一体化系统的方案,此系统具有较好的柔性,包括三个主要的组成部分:前端接口(FE)设备层连接被测系统与一体化系统;仿真环境(SE)部分则能提供航天器各个分系统与空间环境、轨道等要素;测试环境(CE)部分则能自动执行一体化系统的仿真、测试序列,并提供对整个系统运行的管控。文章对这三个部分的实现与相互接口均进行了定义,最后描述了一体化系统适应于不同应用的典型配置,如地面测试系统的评估验证、航天器渐进增量式电测以及故障处理研究等应用。文章提出的一体化系统不但可支持从航天器概念设计、详细设计、AIT等各个阶段的测试工作,也可以用来支持进行航天器故障分析与研究。通过此系统的创建与应用,能够改进航天器研制系统工程,并最终提高航天器的研制效率。

An integrated system for spacecraft simulation and test which is applicable to the satellite development process of CAST（China Academy of Space Technology） is established in this article. Based on the definition and analysis of its function, a flexible system is put forward. The system includes 3 modules： FE（Front--End） equipment, which connects the tested system to get the test parameters; SE（Simulation Environment）, which can simulate all the spacecraft subsys tems and space environment factors, spacecraft dynamics, spacecraft orbit; CE（Checkout Environment）, which executes the test and simulation sequence automatically and control the entire system. Each module is then described in detail and the interfaces between different modules are defined. In the last section of the article, different system configurations are put forward, which are adapted to different applications such as EGSE（Electrical Ground Support Equipment） system evaluation and validation, spacecraft gradual incremental test and research of spacecraft failure handling during different development phases. The integrated system not only supports the test in all spacecraft development phases, from spacecraft conceptual design, detailed design and spacecraft manufacture to AIT, but also can be used in spacecraft failure analysis. The spacecraft development system engineering process will be optimized by the integrated system, and finally the spacecraft development efficiency will be increased.
