空间站维修性系统设计与验证方法研究

Study on Design and Verification Method of Space Station Maintainability

空间站在轨运行时间长,因此需采用维修性设计和在轨维修的方法实现长寿命高可靠在轨运行。根据维修性设计理论,结合工程实际,提出了基于产品特性分析的维修需求分析方法和维修支持下的可靠度计算方法。明确了系统维修性设计应包括布局、供电、信息、故障检测、维修工作模式等设计内容。并根据维修难度,提出了四级维修策略。最后根据在轨维修特点,提出了地面试验验证和仿真验证的方法。为空间站系统维修性设计提供了一个技术途径。

To ensure the highly reliable and long time operation of the space station , methods of ma-intainability design and on-orbit servicing are applied on the Space Station .Based on the theory and engineering practice of maintainability , the demand analysis method according to the product charac-teristic was discussed in this paper .The calculation method for reliability under maintenance support was presented .System maintainability design should include the layout , power supply , information , fault detection and maintenance mode .According to the difficulty of repair , a four level repair strat-egy and the method for the ground test and simulation were proposed in this paper .It is a feasible approach to the space station system maintainability design .
