摘要
为了将可靠性安全性分析融入基于模型的航天任务设计,也必须开展详细的可靠性安全性需求分析.首先,在从需求分解、系统设计的过程中,推导得出各层系统的可靠性安全性需求;结合系统正常需求,在完成系统顶层架构设计的同时,开展功能危害分析、故障树分析等,以验证各层的可靠性安全性需求;依据可靠性安全性需求及对其的验证情况,指导设计故障处置措施,完善系统设计.以美国阿尔忒弥斯载人登月任务设计为例进行了方法验证,为开展基于模型的载人登月系统设计与可靠性安全性一体化分析提供了一种方法.
Reliability and safety requirements analysis should be conducted in detail to integrate reliability and safety analysis into model-based space mission design.During the process of requirements decomposition and systems design,the reliability and safety requirements for the lower-level system are deduced first.Combined with the normal requirements,the top-level architecture of the system is designed.Then,the functional hazard analysis and fault tree analysis are carried out for the architecture to verify the reliability and safety requirements.Based on the verification results,the corresponding solutions for the failure can be designed to improve the architecture of the mission.Finally,the Artemis Program is employed to demonstrate the proposed method.This paper provides a way for the integration of model-based systems design and reliability and safety analysis for the manned lunar landing mission.
