摘　　要：针对复杂航天器供配电分系统全级次数字化模型构建问题,提出一种应用特定域建模(DSM)的航天器供配电分系统架构设计方法,通过抽象供配电领域概念形成供配电领域元模型,基于元模型构建层次化供配电DSM架构模型,通过组件映射和模型转化方法,将DSM架构模型自动生成Modelica仿真模型,开展供配电分系统全链路静态分析和动态仿真分析。以嫦娥五号飞行试验器(CE-5T1)为例,对供配电分系统架构设计方法进行验证,结果表明:该方法实现了设计信息到仿真模型的自动化、一致性传递,提升了仿真验证效率。Aiming at the problems of constructing whole system-level digital modeling for complicated spacecraft power supply and distribution subsystem, an integrated design method for spacecraft power supply and distribution subsystem architecture using DSM(domain-specific modeling) is proposed. A meta-model for the power supply and distribution field is formed by abstracting the concept of power supply and distribution field. The hierarchical power supply and distribution DSM architecture model is constructed based on the meta-model, and the Modelica simulation model is automatically generated by the DSM architecture model through component mapping and model transformation methods to carry out comprehensive simulation analysis of power supply and distribution subsystems. Taking the CE-5 T1 flight tester as an example, the architecture design method of the power supply and distribution subsystem is verified. The results show that this method achieves the automatic and consistent transfer of design infor mation to the simulation model, and improves the efficiency of simulation verification.
