MBSEに基づいた超小型衛星の設計変更時に生じるシステムへの影響範囲の構造的な理解

抄録

This paper is related to the design method of CubeSat using MBSE (Model-Based Systems Engineering) and the purpose is to solve the difficulty of designing a complicated system with strong inter-element coupling such as CubeSat for scientific observation. There are barriers to using MBSE due to the lack of well-defined procedures for introducing it. In this research, we use "SysML", which is one of the standard languages of MBSE system model. This language is characterized by expressing the system from four viewpoints, structure, behavior, requirements and parametric constraints. The procedure for introducing MBSE to CubeSat is explained step by step. For CubeSat, it is difficult to grasp the structure of the problem at the time of design change due to the influence of the strength of inter-element coupling and the complexity of the system. The contents represented by each model written in SysML are sorted. The contents represented by each model written in SysML are summarized.
