基于MBSE的月球科研站任务分析

Mission analysis of lunar scientific research station based on MBSE

月球探测完成“绕落回”三步走后,从单点短期探测向建设月面基础设施的月球科研站长期探测转变,给月球探测任务的规划论证、总体设计、系统研制和在轨探测等提出了更高要求。采用基于模型的系统工程(MBSE)思想,提出基于模型的月球科研站系统分析正向流程,以系统模型为载体深入剖析任务总体、任务使命需求和任务应用场景。通过开展基于模型的月球科研站任务分析,初步实现了月球科研站任务分析过程正向化、设计要素定义全量化、设计要素之间的关联表达显性化、月球科研站工程总体单位下发的研制要求有源化。

After the completion of the three steps of"circling back",the lunar exploration has changed from the short-term single point exploration to the long-term exploration of lunar scientific research stations with the con-struction of lunar surface infrastructure,the higher requirements for the planning and demonstration,overall de-sign,system development and in-orbit exploration of lunar exploration missions are put forward.The thought of model based system engineering(MBSE)is adopted,a model-based forward process for the system analysis of the lunar scientific research station proposal is proposed,and the system model is taken as a carrier to analyze the mis-sion overall,mission requirements and task application scenario.By carrying out the model-based mission analysis of the lunar scientific research station,the process of the mission of the lunar scientific research station has been pre-liminarily realized.
