MBSE在活动发射平台支承臂设计中的应用实践

针对基于文档的活动发射平台系统设计存在的信息离散、关联性差、不易追溯等问题，将基于模型的系统工程(Model-Based Systerm Engineering, MBSE)的正向设计方法引入活动发射平台支承臂方案设计和详细设计过程中，采用SysML语言进行系统建模，采用Modelica语言进行物理建模，采用NX和Ansys进行三维模型设计和仿真，并通过参数结构化和接口配置技术，实现了从系统设计到产品设计关键参数的闭环验证，提高了设计数据的一致性和可追溯性，验证了MagicDraw、Mworks、Teamcenter等系统集成应用的技术可行性，为活动发射平台和其他航天产品设计提供了指导和借鉴。

Application Practice of MBSE in Design of Supporting Arm of Movable Launch Platform

In view of the problems existing in the system design of document-based movable Launch Platform, such as Information Discrepancy, poor relevance, difficulty in tracing and so on, in this paper, the forward design method based on MBSE is introduced into the scheme design and detailed design of the supporting arm of the movable launch platform. SysML language is used for system modeling. Modelica language is used for physical modeling. NX and Ansys are used for 3D model design and analysis. Through parameters structuring and interface configuration closed-loop verification of key parameters from system design to product design is realized. The consistency and traceability of design data are improved, and the technical feasibility of system integration applications such as MagicDraw, Mworks and Teamcenter is verified. This work provides guidance and reference for the design of movable launch platform and other aerospace products.
