Research on modeling and design method of spacecraft system based on MBSE.

Spacecraft missions are characterized by complex missions, high risks, high costs, high reliability, and long periods. In order to meet the needs of more complex spacecraft mission development in the future, model-based systems engineering (MBSE) methods is introduced in the spacecraft design and development. A model-based spacecraft development process and six types of model systems that meet the needs of the spacecraft development process are proposed, which are composed of demand model, function model, process model, architecture model, product model, and verification model. Taking the lunar water resource exploration as a hypothetical task, the MBSE modeling process and its model are presented, which fully embodies the advantages of the MBSE method in spacecraft design and simulation verification.
